Xingshugang-Ⅰ Area Last Well Nets Restructuring Improving Development Effect Index Forecast And Economic Benefit Evaluation

The Daqing Oilfield has entered into the high water cut period, how to keep the stable production has become a problem to be solved. This paper is based on the practice of Xingshugang-1area.We have a research on the drilling degree and perforation situation, and analyze its reservoir sedimentary characteristics, and the reservoir are classified; the remaining oil distribution rule is discussed and the influence factors of remaining oil distribution rule are analyzed.Based on these things,we determine its remaining oil type, reserves, and the changes of the remaining oil; Using numerical simulation method, we set up the experimental geological model; By numerical simulation of water flooding test history matching, we get water flooding the history of numerical simulation fitting results; Through the analysis of the historical fitting results, we can make sure the well nets restructuring optimization scheme, and forecasts the development of each scheme effect indexes, and analyses the economic evaluation.
