为了解决断块油田开发中、后期由于地质情况复杂、注采不平衡引起的新井钻井井涌、漏失问题，在选定的平衡井下液柱压力、相邻注水井停注泄压的适当压井工艺条件下，对老区调整井钻井过程中的出水外溢、井漏等复杂问题进行了调查分析，并结合实例加以佐证，探讨了油田注水开发中由于各种干扰引起的压力异常，对处理技术措施和效果进行了评价。压力异常是调整井钻井井源、井漏的主要原因。
In order to solve the problems of well flushing and leakage of new wells caused by the complex geological conditions and the imbalance of injection and production in the middle and late stages of fault block oilfield development and the selection of balanced downhole liquid column pressure and appropriate well killing of adjacent water injection wells Under the condition of technology, the complicated problems such as spillover and well leakage during the process of well drilling in the old area were investigated and analyzed. Combined with the examples, the paper discussed the pressure anomalies caused by various disturbances in the development of oilfield waterflooding, And the effect was evaluated. Abnormal pressure is to adjust the well drilling well source, the main reason for well leakage.
