| 摘 要： | 常规电缆地层测试器采用流动-关井测试方法,不能进行产能评价。文中分析了大排量地层测试器渗流机理,指出对于大排量地层测试器,流动形态已由球形流过渡到径向流,提出了相应的压力计算方法。设计了类似于钻杆地层测试的程序,采用三开和三关测试程序,计算采油指数,在确定合理压差前提下,可以确定地层产能。

| Abstract: | Regular formation tester that adopted flow-shut in testing procedures can't evaluate flow potential. For high duty pump formation tester, it's flow state is transferred from spherical to radial flow. The paper analyzed its percolation mechanism, proposed mathematical models of pressure, designed testing procedure which similar to stem formation test The high duty pump formation tester use three flow - three shut in testing procedure to calculate productivity index, based on rational pressure difference, reservoir flow potential will be determined. |
