介绍了XQ1井压力计辅助双封隔器验窜的全过程,该工艺是为解决常规封隔器验窜资料录取不完整而设计的,不但设计了记录地层情况的2支压力计,还有1支压力计专门验证封隔器的密封性,通过对比验封2个层位以及2封隔器间的3条压力曲线,提供了地层验窜的详实资料,地层窜槽与否一目了然,为科学决策提供了依据,避免了返工。

The paper introduces the whole WBT examination process of using double packers in the pipe string with monitoring by pressure gauges in XQ - 1 well. It is designed to solve the problem that the data obtained from WBT examination using routine packers are not complete. Three pressure gauges are designed in the technology. Two of them are used to record the pressure of the formation, and the rest one is designed to monitor the seal condition of the packers. Therefore, three pressure curves may be obtained during the test. The detail data of formation WBT can be obtained in the comprehensive contrast of the three curves, and WBT can be founded obviously.The foundations related scientific decision can also be presented by the work, and many repeating work can be avoided.
