摘要
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。
This paper investigates and analyses the complex problems of watered out,overflow and lost circulation in the process of adjustment well drilling in old area, and gives an evidence combined with a case. It also discusses the abnormal pressure resulted from the inconsistent disturbance during waterflood development of oil field, and evaluates the handling technology, handling measure and its effect.
