任丘雾迷山组碳酸盐岩油藏自1976年投入开发至今四年多,积累了大量的生产实践资料,并分析研究了开发中的一些主要问题如合理采油速度及井网密度等,从去年开始又应用双重介质单井水锥数值模型研究了该类油藏油井生产过程中水锥的形成、发展过程及各种参数对油田开发指标的影响,并提供了较可靠的对比依据。该模型要求油水在裂缝性灰岩油层中运动符合的基本条件是:①油水在裂缝中的运动
Renqiu Wumishan Formation carbonate reservoir has been in development for more than four years since 1976, accumulating a large amount of production practice data and analyzing some major problems in development such as reasonable oil recovery rate and well density, Starting from last year, the dual-media single-well water coning numerical model was applied to study the influence of water coning, development process and various parameters on oilfield development in the oil well production process and provide a more reliable basis for comparison. The model requires that the basic conditions for oil-water movement in fractured limestone reservoirs are: ① oil-water movement in the fracture
