Based on the geological conditions,Water flooding characteristic and the current difficult of stable yield of Ba-19 fault block,Huabei Oilfield Company have employed the overall microbial circulating oil displacement technology by established stable microbial field in this block. Firstly, four strains of efficient production microbes were screened from target reservoir. The laboratory study indicated that the four kinds of microbes could not only well adapted to the reservoir environment, but also had the good viscosity reduction and emulsifying effect for crude oil. The gas chromatography (GC) analysis showed that the screened strains could use the crude oil as carbon source, and degrade long-chain hydrocarbons effectively. Especially by compounded these microbes according to equal proportions, the viscosity reduction rate reached up to 52.8%, and based on 49.5% oil recovery of the water flooding, the oil recovery was enhanced by 9.1% by physical model experiment. The microbial concentration in target reservoir reached 105-106 cells/mL and maintained over 8 months. The results demonstrated that the injected target microbes could grow and reproduce effectively in reservoir. The water cut was controlled lower than 85% and the oil recovery improved obviously. The cumulative incremental oil was 15000 t within 12 months,and the input-output ratio was up to 1: 2.5.

The conventional dynamometer diagram diagnosis method of rod pumped well has the function to calculate the well yield based on the downhole dynagraph. In recent years, it can substitute for the traditional separator metering mode technically through further development and support to measure the oil well in an automatic and remote manner, analyze the working conditions and alarm in a real time manner, thus simplifying the collection process and improving the metering accuracy and working efficiency. In this paper, the technical and management problems in development and application of automatic metering technology of rod pumped well dynamometer diagram in Huabei Oilfield are discussed and solutions are proposed in order to guide the wide application of such technology in Huabei Oilfield. © (2014) Trans Tech Publications, Switzerland.

The generation mechanisms of complex fracture mesh and the mechanism of activating existing natural fractures during shale fracturing are studied based on rock fracture dynamics. It is found that steering conditions should be satisfied at both the left and right ends of a natural fracture to form an intensive fracture mesh after the induced hydraulic fracture reaches the natural fracture; there exists a minimum critical pump rate (critical pump rate) to form an intensive fracture mesh. The critical pump rate increases as the inclination of the natural fracture increases and reaches a maximum value (constant) when the inclination of the natural fracture is 90°. When the inclination of the natural fracture is less than 90°, the critical pump rate first decreases and then increases as the angle between horizontal wellbore and the natural fracture increases; the critical pump rate reaches a minimum value for the natural fractures perpendicular to the wellbore. The critical pump rate increases as natural the fracture length increases and the rock elastic modulus decreases. When hydraulic fractures reopen existing natural fractures, the release of the original shear stress in the fracture surface would lead to the fracture surface slippage, which would greatly enhance the flow conductivity of the natural fracture. Very small or very large inclination of natural fracture is not conducive to fracture activation, best activating result can be reached at 30-60° inclination. Rise in elastic modulus inhibits fracture surface slippage and Poisson's ratio has little effect on fracture surface slippage. © 2013 Elsevier B.V.

A yellow-coloured bacterial strain, designated HB2T, isolated from stratum water was investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore- forming, non-flagellated and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was a member of the genus Luteimonas, its three closest neighbours being Luteimonas aquatica BCRC 1 7731T (97.5% similarity), Luteimonas marina JCM 12488T (97.3 %) and Luteimonas aestuarii DSM 19680T (96.9 %). Strain HB2T could clearly be distinguished from these type strains based on phylogenetic analysis, DNA-DNA hybridization, fatty acid composition and a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strain HB2T represents a novel species of the genus Luteimonas, for which the name Luteimonas huabeiensis sp. nov. is proposed. The type strain is HB2T (=DSM 26429T=CICC 11005sT). © 2013 IUMS.

The packer rubber stress in the bottom hole is more complex. Based on constitutive model of the packer rubber material, this paper determines such parameters as model constants, Poisson's ratio of rubber materials and elastic modulus by using experimental method, to build up the finite element model of center tube-rubber cylinder-casing for the purpose of stress analysis. Finally, the distribution regularity of rubber cylinder-casing contact stress and packer setting travel distance with varying loads is concluded. The results can provide the theoretical basis for further analysis of packer rubber sealing performance. © (2014) Trans Tech Publications, Switzerland.

In order to utilize the beneficial Indigenous Microbial in objective reservoir, active formula systems with various nutriment components were investigated[1]. The results of performance evaluation showed that the activation, emulsification, viscosity break, and oil displacement performance of nutritional formula system were approved. Based on the field verification, the beneficial Indigenous Microbial in produced fluid of post treatment well array was activated, oil quality was improved, displacement efficiency was advanced, and oil production was increased. © (2014) Trans Tech Publications, Switzerland.

In view of high heterogeneity and complicated oil-water relation of fault block oil reservoirs, conventional technology of water plugging and profile controlling cannot well adapt to it. An oil-in-water emulsion for selective water plugging was designed by using emulsified heavy oil for reference and the aim was to improve the injection ability and plugging strength. The single core flooding results indicated that its breakthrough pressure gradient >26MPa/m,water plugging rate >97% after water flooding for 100 pore-volume. The parallels core flooding results indicated that it has good water flooding endurance than emulsified heavy oil, and can be used to the selective water plugging and profile controlling of heavy heterogeneous layers with the permeability ratio is no less than 7. Field application is successful. © (2014) Trans Tech Publications, Switzerland.
