Comparative Analysis of Numerical Simulation Development Plans for Water Flooded and Water Channeling Reservoir
摘要
Abstract
With the deepening of development, most oilfields have entered the stage of high water cut. Taking a waterflooded water channeling reservoir in Xinjiang as the research object, the area is seriously flooded and the development effect is poor. In view of the above problems, four technical schemes to improve the development effect are studied by means of reservoir numerical simulation. The results show that the deep profile adjustment scheme has obvious production increase effect, which can effectively improve the daily oil output and reduce the water cut; the shallow profile adjustment scheme has limited effect range and effect time, and the effect is poor; the water cut of the well pattern adjustment scheme decreases significantly, and the oil output increases, the oil increase effect is between the deep profile adjustment and the shallow profile adjustment; the cycle water injection increases the oil increase effect is the worst, showing a negative growth trend. Through the comparative analysis of the schemes, it is suggested to implement the deep profile adjustment for the wells with serious water crossing in the study area. This study provides important theoretical guidance and reference for improving the development effect of similar water flooded water channeling reservoirs.关键词
