克拉玛依油田一区石炭系火山岩油藏试井研究

WELL TEST ANALYSIS FOR THE CARBONIFEROUS RESERVOIR OF VOLCANIC ROCK IN DISTRICT NO.1, KARAMAY OILFIELDS

本文简述了克拉玛依油田一区石炭系油藏复压曲线的解释结果,并通过质量检验,与油藏地质、油井生产和油田开发动态实际对比,证明解释结果是可靠的。在此基础上,着重研究了该油藏复压曲线的形态特征及其形成机理,得出一区石炭系火山岩油藏属于非典型性裂缝—孔隙双重介质油藏类型。最后,从油藏开发应与油藏地质特征相一致的原则出发,提出了改进注水方式的技术要求。

Results of pressure build—up analysis for the carboniferous reservoir in District No. 1 are briefly described in this paper. Its reliability is confirmed through quality checking and comparison with the reservoir geology,well production as well as reservoir production performance. The characteristics and its forming mechanism are discossed empha—tically based on proceeding studies. It is concluded that the Carboniferous reservoir rock in District No. 1 is an nontypical, fracture—matrix dual porosity type. Finally, specifications related to improving water injection pattern are proposed based on the principle that reservoir production scheme should be consistent with reservoir geology.
