| 摘 要： | 毛细管测压技术是以氮气作压力传递介质，将井下压力传递到地面，在地面完成压力的测试，再将所测压力推算至井下测压深度处压力的一种测压技术。该技术具有测压精度高、井下部分结构简单、地面部分工作寿命长且易于检修的特点，能够完成各种稳定试井和不稳定试井工作，适用于直井、斜井、水平井和稠油热采井的单层测试和分层测试，满足机械采油和自喷采油不停产进行测试的要求，更适合海上油田使用。

| Abstract: | Piezometric technique with capillary tubing is a kind of technique which transfers downhole pressure onto surface by taking nitrogen as the pressure transfer medium, tests the pressure, and then based on it reckons the pressure at the piezometric depth.The technique has the characteristics of high accuracy of piezometry, simple structure ofdownhole part, long service life of surface part and being apt to turnaround, it can accomplish various kinds of systematic well testing and transient testing job, is suitable to single zone testing and multi-zone testing in vertical well, inclined well, horizontal well and viscous oil thermal recovery well, can satisfy the demands of testing in artificial lift well and flow production well without stopping production, and is more suitable to the use in off shore oilfield. |
