摘要
春光油田排2块属于埋藏浅、高孔、高渗、稀油、边水非常活跃的砂岩油藏，其开发最核心的问题是如何用好边水。为此，应用矿场生产资料、系统试井资料、同类型油藏类比、油藏工程方法、数值模拟方法、渗流力学理论研究了开采对策，得到了IPR方程、合理的生产压差及通过油嘴公式评估单井产量，推导出了边水推进速度方程，编制了专门软件，实现时时计算边水推进速度，并不断优选合理的工作制度。排2井区2005年开发以来产量稳步上升，保持自喷开采，边水水线缓慢、均匀推进，含水率仅为2％，采油速度、采收率同创国内新水平。
Block Pai 2 in Spring Oilfield belongs to light oil sandstone reservoir, with characteristics of shallow buried, high porosity, high permeability and active edge water. Its critical development problem is how to make good use of edge water. Through application of field production data and well performance testing data, IPR equation and reasonable production pressure difference are obtained, by means of analog with same type of reservoir, reservoir engineering method, numerical simulation method and fluid flow mechanics theory. Single well production is assessed with choke formula. Edge water-advancing rate equation is deduced. Special software is developed to obtain the real time advancing rate of edge water. A reasonable working system is continuously optimized. The production of Pai 2 well field has increased steadily since its development starting in 2005, where flow production is maintained, edge water advances slowly and evenly. Its production rate and recovery rate both create a new domestic level with only 2% of water cut.
