Urban underground water supply network is so anfractuous that a large amount of data requires to be processed, and that the traditional manual method or recurring to drawings can hardly meet the demands. Thus, a scientific, standardized, and automatic management system is imperative. On the study of actual status in medium-sized city, this paper presents a method to establish service pipe network management system. ArcGis, OCXs and SQL database are introduced to create or show data sets and graphical elements. The consistency of graphical elements and data sets ensures the automatic operation of control points, and realizes the automatic link with drawing software and graphics. On the purpose of providing reliable basis for emergency repair, design and construction, the designed system accomplishes the inquiry editing function of pipeline route, user information, unit worker information, valve, valve shaft and well pictures. At the same time, it can also meet the need of data updating, figure editing, database information modification. It makes the water supply network management easy, facile and exact, realizes the function of map browsing, zooming in, zooming out, roaming and adding annotation, also increases the applicability of the management system. © 2011 ASCE.

Nowadays, in China nearly all the produced oil-fields have already entered the period of high water cut, and the six oil-fields of Daqing and Shengli oil-field etc. have exceeded eighty percent water cut. Beierdong Block has produced for nearly fifty years, and now it has entered into the descending output stage and its water cut has reached more than ninety percent. With oil field infill gradually in Beierdong Block, each series of well network production target getting worse gradually, intersecting with old well network stratigraphic position, and polymer flooding well network use part of water driving old well, making the contradictory of layer well network concatenate and dynamic regulation intensely. Especially as the block of infill adjustment proceeded earliest, acquired better developed effect at the beginning of regulation, but with the deep development of the field, after the phase of extra high water cut, exposed gradually some problems such as the perforating interval is too long, the contradiction of interlamination is obvious, the high water cut of multilayer is serious, bringing huge difficulty to dynamic analysis regulation[1]. Basing on layer recombination and using the reservoir simulation method, the paper studied the distribution of remaining oil, forecast variation regular pattern of development indexes. By contrasting these indexes, the paper estimates the effect of layer recombination. It has important significance for the next period's development. © (2012) Trans Tech Publications, Switzerland.

The study and construction of domestic gas storage is in its infancy, although the design of in injection and production wells, surface technology and operation technique is groundbreaking, but because its running time is short, in systemic dynamic monitoring technology has not yet formed during the process of gas storage injection, the ancillary well testing equipment has not been completed. Combined with actual state of Wen96 gas storage, gas storage development around the requirements of Wen96, the well testing equipment suiting for its gas storage is developed, and remarkable results have been achieved when applied on site.

The Sanghe sub-sag in Baiyinchagan sag develops three sets of source rocks, i. e. the first Member of Duhongmu Formation, Tenggeer Formation and the second Member of Aershan Formation, with long hydrocarbon generation time, multiple-accumulation periods and well-developed faults. It is favorable for the formation of the commingle crude oil in the geological and geochemical conditions. The three sets of source rocks are the important oil sources in Sanghe region. The analytical data of biomarkers and carbon isotope from crude oil show that crude oil in the region can be divided into three types, primary low mature crude oil, primary mature crude oil, and blend crude oil. The first two types of which come from lower Member of Tenggeer Formation and the second Member of Aershan Formation, they are the hydrocarbon products in different periods of source rocks. The third type of crude oil, typical binary blend crude oil, comes from the mixing process of the first two types.
