本文在现场调查的基础上,结合纯油区东部的实际生产情况,围绕改善欠注井的注水效果的目标,对欠注井的欠注原因进行了细致的分类,提出了欠注井及欠注层的分析要与注采对应分析、油水井连通性、监测资料对比分析、井史追踪的综合分析方法相互结合,并采取了针对性的措施,取得了较好的效果,以解决不吸水及欠注井的注入问题,完成“注够水、注好水、有效注水”的目标。
Based on the field investigation and the actual production situation in the eastern part of the pure oil zone, this paper focuses on the aim of improving the water injection effect of underfilling wells, The analysis of the injection layer should be combined with the corresponding analysis of injection and production, the connectivity of oil and water wells, the comparative analysis of monitoring data, and the comprehensive analysis method of well-history tracking, and taken specific measures and achieved good results to solve the problem of non- And injection wells injection problems, to complete “enough water, good water, effective water ” goal.
