环空测试中电缆缠绕油管的分析与排除

Analysis and Elimination of Wireline Tangle around Tubing in Annulus Test

环空测试技术是一种新兴的,从抽油井油管和套管环形空间起下下井仪器,直接测取油井生动态参数的测试方法。环空测试中,电缆缠绕油管的预防和有效的排除是该技术成败的重大技术键。根据我国环空测试技术的设备特点,文中分析了电缆缠绕油管的原因,提出了预防和排除的法。

Wang Qian,Anaiysis and Elimination of Wireline Tangle around Tubing in Annulus Test.WLT,1993; 17(3):233～238 Annulus test is a new technique in which logging tools are run between tubing and casing and dynamic production parameters are directly acquired from oil well.A key to the success of the test is to prevent wire- line from tangling around tubings effectively.Based on the features of the equipment used in annulus test in China,the reasons of wireline tangle are analysed,prevention and elimination method are given herein.
