摘要
MFE工具与井口加压结合的验窜方法根据MFE地层测试的工作原理 ,下井管柱采用单封隔器的结构 ,下部带电子压力计和机械压力计监测。首先人工在井口环空观察液面变化 ,然后用高压泵车在环空加压。起出管柱后对环空的变化情况及压力计的压力卡片进行综合分析以确认窜通点。运用该方法在塔 30 18井的八个验窜点中 ,找到了二个窜通点 。
Based on the theory of MFE formation tests, a WBT examination method of MFE combining MFE and wellhead loading is presented. The method includes that single packer are used in the pipe string with monitoring by pressure gauges electronicor mechanical. In cannula, first liquid level can be observed; second pressure can be loaded by using the truck with high pressure pump. WBT point may be affirmed in terms of synthetical analyses of both changes of the liquid level in the pipe string and the card of pressure gauge recorded. Two of eight the WBT points in Ta18 30 well have been founded using the method. Scientific foundations related the further bottomhole blockage can also be obtained by this method.
