改善注聚油层动用程度的合理压力系统
Reasonable Pressure System for Improvement of Use Degree of Polymer Injection Layers
摘要
Abstract
For the phenomenon that the rapid rise of water cut and a big difference in using degree between various layer types in the late stage of polymer injection,a new method that has achieved good results in field test is proposed.The flow pressure can be reasonably adjusted by stage andproduction levels can also be determined.For example,Lamadian Daqing Oilfield, variation of development indicators(such as production,pressure profile,etc)is studied after adjusting flow pressure through numerical simulation techniques.Compared to development effect,it is showed that when flow pressure is kept 6 MPa(higher)-2 MPa(lower)-6 MPa(higher),water cut is reduced by 1.46 percentage points,and degree of polymer flooding cumulative recovery is reduced by about 2.43 percentage points after 1.0 PV is injected,of which producing degree is best.关键词
