孤岛油田渤21断块水体能量评价方法的研究与实践

Research & Practice on the Evaluation Method about the Water Body Energy of Bo 21 Fault-Block in Gudao Oilfield

油藏水侵计算公式已被普遍地认识。然而，在边底水油藏水体能量大小估算中存在的许多实践问题限制了它的应用。本文基于胜利油区孤岛油田渤21断块20a注水开发历史，对该区水体能量进行了评价，并在此基础上建立起一套完善的边底水能量评价的程序与方法。同时，对实践中的具体问题（如奇异数据点的影响）进行了讨论。

Although water influx rate formula has been recognized widely,many problems existing in calculating energy of water body in edge-bottom waterdrive reservoir restrict its application. Based on 20years, water flood development history of Bo 21 Fault-Block in Gudao Oilfield,evaluation of water leg's energy is proposed. Then,this paper gives the procedure and method to valuate the edge-bottbm aquifer's energy. Also,problems in practice (for example,the influence of singular datum) are discussed.
