Oil Shale | Year: 2016

Analysis of the abundance and type of organic matter of oil shale in the sequence stratigraphic framework of the Middle Permian Lucaogou Formation at the northern foot of Bogda Mountain, NW China, was carried out. The Lucaogou Formation consists of two well-completed 3rd order oil shale sequences, sequence 1 and sequence 2. With respect to organic matter abundance, in each sequence, the TOC of oil shale in the lowstand systems tract (LST) and the regressive systems tract (RST) is of medium abundance. The TOC of oil shale in the transgressive systems tract (TST) is of higher abundance, and in the highstand systems tract (HST), of highest. In regard to type, the organic matter of oil shale in the LST of either sequence is mainly of type II2 or type II1. In TST and HST, it is predominantly of type II1 and type I, respectively, and in RST, of type II1 or II2. The proportion of lake algae in the organic matter of oil shale is the highest in HST, while the share of terrestrial plants is the highest in LST and RST. Being originated from lake algae and terrestrial plants, the organic matter of oil shale in TST is of mixed type. © 2016 Estonian Academy Publishers.

The petrography, mineralogy and geochemistry of sedimentary rocks from the lower Cretaceous Muling Formation (K1ml) in the Laoheishan basin, northeast (NE) China are studied to determine the weathering intensity, provenance and tectonic setting of the source region. Petrographic data indicate the average quartz-feldspar-lithic fragments (QFL) of the sandstone is Q = 63 %, F = 22 %, and L = 15 %. Lithic fragments mainly contain volcanic clasts that derived from surrounding basement. X-ray diffraction (XRD) data reveal abundant clay and detrital minerals (e.g. quartz), as well as minor calcite in the fine-grained sediments. The Hf contents and element concentration ratios such as Al2O3/TiO2, Co/Th, La/Sc, and La/Th are comparable to sediments derived from felsic and intermediate igneous rocks. The strong genetic relationship with the igneous rocks from the northwest and northeast areas provides evidence that the sediments of the Muling Formation (K1ml) in the Laoheishan basin have been derived from this area. The chemical index of alteration (CIA) and index of chemical variability (ICV) reveal an intensive weathering in the source region of the sediments. The multidimensional tectonic discrimination diagrams indicate that the source rocks of K1ml are mainly derived from the collision system. However, they may also comprise sediments derived from the continental rift system. The results are consistent with the geology of the study area. © 2016 Springer-Verlag Wien

Through testing single-axial compressive strength, modulus of elasticity and Poisson's ratio of rock samples collected from outcrop areas in Tarim basin, including Kuqa depression, Keping uplift and Bachu uplift, the section showing the rock mechanics characteristics of the Tarim basin is completed. The comprehensive analysis of stress-strain curves of the samples shows the influence of the rocks structure on their mechanics characteristics, which offers accurate experiment data for analyzing differential layered and detachment structural deformation. Based on the seismic reflection profile, taking the Selibuya faulted-anticline which is the boundary fault of Bachu area as example, geometry deformation style and mechanism are analyzed. Structural recovery is based on mass-spring equation, and strain analysis based on this fact that the sandstone of Silurian and Devonian are capable layers. The research result indicates that, because its rock mechanics properties is far higher than adjacent formations, the Silurian and Devonian sandstone dominate the distortion of overlying strata and inhibit the vertical deformation of deep layers. Profile explanation result reveals that the gypsum within the Aertashi Formation at the bottom of the Paleogene and lower-middle Cambrian acts as the detachment layers, corresponding to the rock mechanics parameters obtained from laboratory. Combined with deformation analysis and stress-strain analysis of Selibuya faulted-anticline, it can be concluded that, for the same structure under the same stress field, structure deformation is not only controlled by the mechanical property of rock, but also decided by its structure position and deformation behavior.

The purpose of this paper is to analyse the poly-phase differential movement and deformation mechanisms of the fault structures of the Tarim Basin. Based on the seismic profile interpretation, comprehensive analysis of the drilling and geologic data as well as compiling the fault system figures of the different stages, it is indicated that the main tectonic stages controlling the formation and evolution of the fault structures in the Tarim Basin are Early Caledonian, Middle Caledonian, Late Caledonian-Early Hercynian, Late Hercynian, Indosinian, Yanshanian, and Himalayan. During the Early Caledonian, the fault movement was controlled by extensional regime and formed a series of normal faults along the pre-existing basement fault belts. During the Middle Caledonian and Late Caledonian-Early Hercynian, it is characterized by thrust faults, mainly distributed in the east Tarim, middle Tarim, Tangubasi, Bachu and Maigaiti regions. It is also characterized by thrusting during the Late Hercynian, and migrates from middle Tarim, Tangubasi, east Mazhatag which the fault movement is intense in the early stages to the north Tarim uplift and east Tarim. A series of fault belts formed in the foreland area during the Indosinian, Yanshanian, and Himalayan, originated a lot of imbricated thrust faults, fold-thrust belts, duplex structures and salt-related structures. The fault structure undeveloped in the stable region of the basin such as the north Tarim uplift, middle Tarim uplift, Awati-Manjar depression during the Meso-Cenozoic. The fault deformation mechanisms during the Paleozoic may have a bearing upon regional tectonic regime change and tectonic transform, pre-existing basement fault zone, major regional unconformity, main detachment zone. The regional tectonic regime change and tectonic transform are mainly controlled by the time and intensity of the extension, subduction and closure at the peripheral oceanic basins during the Paleozoic. The preexisting basement fault zone or weak zone may control the later stage fault position and orientation. The major regional unconformity and main detachment zone may control the fault development and distribution horizons. The fault deformation mechanisms during the Meso-Cenozoic maybe related to the regional tectonic regime and tectonic position. The fault structures develop in the three environments of the foreland, stable and erosion regions during the Meso-Cenozoic. The fault structures undeveloped in the stable regions of the basin. The fault belts during the Meso-Cenozoic mainly develop in the foreland tectonic regime and are controlled by rapid intense rise of the peripheral orogenic belts, compression and thrusting, wrench-thrust or thrust-wrench, as well as the basin-mountain coupling at the Late Himalayan and detachment layers.

Polymetallic iron ore sulphate deposits of marine volcanic rock have been developed in the Fangniugou area, Jilin Province, China, but the division of volcanic ore-bearing strata has not been specifically elucidated and there is disagreement about the division. The sampling and SHRIMP U-Pb zircon dating of volcanic rock for Daheishan in the Fangniugou area and the northeast slope of the Duanjiadian were described. The volcanic rock formation period and recorded the volcanic events in the Daheishan mountains were systematically researched. Two samples of high-precision U-Pb zircon dating were used to represent the volcanic rock fomation period of the Late Silurian. The measured data reflect that multiple volcanic activities occurred during the Middle Silurian, Early Silurian, Middle Ordovician and Silurian, and Late Ordovician, probably matching volcanic events in the Songnan Basin identified from zircon dating. At the same time, it is confirmed that a controversial "conglomerate of Daheishan" did in fact develop in the Late Silurian, and those sections of both the Dazigou and Xinlitun-Taoshan with graptolite had been reversed. © 2014 Central South University Press and Springer-Verlag Berlin Heidelberg.

The superimposed basin is of poly-phase differential structural deformation controlled by key tectonic stages. Five tectonic reform stages, that is mid-Caledonian, Late-Caledonian-Early Hercynian, Late-Hercynian, Indosinian-Yanshanian, and Himalayan, maybe recognized from deformation analysis in the Tarim basin. The development and evolution of the Tarim basin are affected by the main tectonic reform stages. According to the analysis of known oil-gas belts of northern Tarim uplift, mid-Tarim uplift and Kuqa depression, it is indicated that the huge marine carbonate paleo-karst oil-gas pools are controlled by the faulting and folding, uplifting and erosion, and karsting during the period of the Paleozoic tectonic reforms. A large number of hydrocarbon accumulation in the foreland fold-thrust belt are controlled by the Meso-Cenozoic tectonic reforming. All these known hydrocarbon accumulation zones are finalized at the Late-Himalayan movement, forming hydrocarbon accumulation model of the poly-phase reform-late-stage finalization composite tectonics. Analyzing the poly-phase differential structural deformation, an evaluation and strategic selection of oil-gas resources in the new exploration areas of the Tarim basin have been made based on the above-mentioned model. It is proposed that the best new exploration regions are Bachu uplift, Maigaiti slope and foreland fold-thrust belt on the west Kunlun Mountain footwall. And the eastern Tarim, Tangubasi depression and Awati fault-depression are of favorable oil-gas exploration prospects.

The salt beds of the Middle-Lower Cambrian are widespread in the middle-west parts of the Central Uplift and adjacent areas, the Tarim Basin. This paper presents the results of seismic interpretation and drilling data analysis, which discovered that the salt beds were formed in an old geologic age, deeply buried, with relatively small scaled flowing and gathering and uneven distribution. As the regional detachment layers, the salt sequences considerably control the structural deformation of the up-salt Paleozoic, forming a series of hydrocarbon traps. In due course, the salt beds of the Middle-Lower Cambrian provide excellent cap rocks and trap conditions; thus the value of exploring hydrocabon reservoir in the target strata of the sub-salt Sinian-Cambrian is greatly increased. Research has shown that the salt-related structures of the Middle-Lower Cambrian in the area mainly exist in the form of salt pillow, salt roller, up-salt anticline, salt diapir, assemblage of the salt arch and up-salt fault-block, assemblage of basement fault and salt anticline, assemblage of the basement fault-block and salt dome, assemblage of salt detachment and fault-related fold, and assemblage of basement fault-block, salt arch and up-salt imbricated thrusts. The evolution and deformation mechanisms of the salt-related structures are controlled largely by basement faulting, compressional shortening, plastic flowing and gathering, superstratum gravitation, and up-salt faulting and detaching. They are distributed in rows or belts along basement faults or fault block belts. © 2012 Science China Press and Springer-Verlag Berlin Heidelberg.

With the development of Internet, basic information services can no longer fulfill some customers' requests, which requires information service brokers to provide value-added services to improve their information service quality. Based on the web service architecture, this paper constructs a value-added service model of mining right information from the perspective of information value-adding, and describes the information value-adding process. In this paper, we also illustrate different levels of mining right information service workflows. The proposed value-added services of mining right information are initiative and two-way services, which can enhance information value to meet customers' information requests. © 2010 IEEE.

Based on results from the field geology investigation, seismic interpretation, sedimentary analysis, and a great number of samples tests, the semi-deep lake facies were developed in the Kangsu Formation of the Lower Jurassic in Washixia sag and in the Yangye Formation of the Middle Jurassic in Minfeng sag and Washixia sag. The source rocks of Jurassic lacustrine facies were developed on the top of the Yangye and Kangsu Formations, mainly distributed in the south central part of Washixia sag and Baxikangsulake-Pulu area of Minfeng sag. The Lacustrine source rocks are mainly Mudstone with great thickness, organic matter of type II–III, high organic matter abundance, TOC of generally more than 2.0 %, and PG in the range of 2–6 mg/g. With the thermocompression simulation experiment, the source rock generated hydrocarbon up to 300 mg/g TOC. The source rock is good at the thermal evolution stage of low mature to mature. We conclude that the source rocks of the Yangye and Kangsu Formations in the central south of Washixia sag have better exploration potential with good hydrocarbon-generating conditions. © 2013, Saudi Society for Geosciences.
