自 8 0年代初期 ,抽油井环空测试技术在我国各油田逐渐开展起来 ,各种类型的测试仪器和工具也相继产生 ,但是 ,在整个发展过程中对井下测试工具的开发较迟缓。目前抽油井环空测试管柱类型有光油管、防砂管和卡封分采管等。抽油井环空测试的主要参数有产液量、油量、含水、压力 Since the early 1980s, the annulus test technology of pumping wells has been gradually developed in various oil fields in China. Various types of testing instruments and tools have also been produced successively. However, the development of downhole testing tools has been slow in the development process. At present, the pumping well annulus test tube type light tubing, sand control and card sealing tube. The main parameters of pumping well annulus test are liquid production, oil quantity, water content and pressure
