The Detailed Study Of The Songliao Basin In West Gaotaizi Reservoir

Perforations in2009, the secondary development of mature oilfields, and reconstructionof underground understanding of the system, rebuilding the structure of the well network,restructuring of the ground process. This paper mainly studies in West Gaotaizi reservoirs inthe process of secondary development, starting from the fine geological studies to analyze theprincipal contradiction, applications and digital-analog techniques, analysis of the distributionof residual oil, and put forward feasible adjustment programs, the program follow-up study ofthe implementation of the development of law and development effects, the late high watercut,106m Well Spacing, effective thickness of less than0.5m and Table reservoir trackingadjustment of the effective governance and technical support.West block reservoir exploitation process Gaotaizi there are three major problems: First,the injection wells, water absorption capacity can not meet the requirements of stable extract;second, more to the connectivity of the thickness of the proportion of small, is not conduciveto improve the ultimate recovery factor of oil field, by increasing the injection wells point, inorder to improve the development effectiveness; unbalanced pressure of the well interval, thepressure downward trend; high moisture content of the side wells inject water to a lowutilization rate.
