摘要
分层注水技术是维持油田稳产高产的重要手段,影响分层注水的因素有地质条件、开发现状和工艺措施等。研究选用RMsimple软件建立利津油田利8区块地质模型,根据数值模拟的结果,分析利8区块存在层间矛盾突出、水井细分程度低、地层压力下降等问题,提出油水井补孔,提高井间连通方向数,水井细分注水等措施。2014年5月,利用智能分采分注配水系统对利8区块3口水井实施分层注水,截止到2014年6月实现累计增油271.1t,平均单井日产油增加2.2t,起到了减缓层间矛盾、增加有效注水的效果。
Layered water injection technology was an important means of maintaining high and stable production in oilfields.The factors affecting the layered water injection included geologic condition,development situation and technical measures.The simple RM software was used to establish a geological model of Block Li 8,based on the results of the numerical simulation,the problems of severe low level of fine division of water wells and fast drawdown of formation pressure were analyzed in Block Li 8.Measures were proposed,which included reperforating in oil and water wells,enhancingthe inter-well number of communication direction and fine division of the injection wells.In May,2014,the smart layered water distribution system is used in 3wells in Block Li 8.By the end of June,2014,the cumulative oil increment is 271.1t,the average daily oil production increase of single well is 2.2t,the technology can mitigate contradiction between layers and to improve the effect of water injection.
