摘要
讨论了文东油田文 1 3北块油藏开发动态 ,分析了该油藏的产量递减规律、水驱特征曲线、含水上升规律及产液剖面和吸水剖面 ,指出开发中存在的主要问题是 :1注入水水窜 ;2注水井堵塞 ;3储层非均质性制约水驱波及体积的提高 ;4注入水利用率低。建议采取以下措施 :1尽早对低渗透层进行酸化、压裂 ;2加强注水井调剖和油井堵水 ;3提高注入水水质 ;4加强油藏监测 ;5进一步完善注采系统。
The reservoir production performance of the North Block Wen 13 is discussed, the analyses are made on the rules of production decline, the characteristic curve of water flooding, the rules of water cut increase and fluid producing and water absorbing profiles;the problems existed in production are pointed out, which include:①water channeling in injected water;②blocking of water injecting well;③the reservoir heterogeneity controlling the increase of swept volume of water flooding;④low usage of injected water Precautions are taken , which include:①acidizing and fracturing the low permeable zones as early as possible;②strengthening profile adjustment and water plugging;③improving the quality of injection water;④strengthening the reservoir detection;⑤further improving the injection and production system
