胜利断块油藏人工边水驱提高采收率技术研究

摘要

通过对胜利油田高采收率断块油藏地质开发特征的分析研究,归纳总结了其获得高采收率的成功开发经验.在此基础上,提出了借鉴其成功经验和做法开展人工仿强边水驱开发断块油藏的技术思路.矿场试验研究表明可以实现剩余油的有效动用和高效波及,而且对断块油藏进一步提高采收率具有重要意义.同时这还有利于油田的污水减排工作,具有较高的社会经济效益.%According to the analyse and research on geology & development feature in high-recovery fault-block oil reservoirs of Shengli oilfield, the successful development experience which obtained higher oil recovery and belter economic benefit was summarized. Base on it, the technology thoughts about simulating Strong edge-wate to develop fault-block oil reservoirs by injecting water was bringed forward. Using the technology, the remaining oil in fault-block oil reservoirs will be obtained effective startup and high-efficienc sweep. However the technology will be propitious to improve recovery ratio and save water and reduce wastewater emission. The ecological, economy and social benefit will be very salient
