变排量抽汲测试测取产液剖面技术

Variable displacement swabbing test for fluid producing profile measuring.

为准确找出油井的出水层段,研究了变排量抽汲测试产液剖面技术。该技术在油井检泵作业施工期间进行,通过油管驱动产液,测试仪器从油管下入并过泵柱塞到达测试层段,进行不停抽变排量测试。得到产液剖面资料。该技术适用于斜井、稠油井、螺杆泵井、电潜泵井、水力泵井等无法进行环空测试的油井。在华北油田实施了50余井次,为油田开发方案的判定提供了较为准确的资料。

Variable displacement swabbing test technology for fluid producing profile measuring was developed to accurately find out the water production interval of oil wells. This technology was conducted while the construction time of pump checking operation. The testing instruments were run down along the tubing into the testing interval, and variable displacement swabbing test was conducted. This technology was fit for those wells which couldn't be conducted annulus logging, such as inclined wells, heavy crude oil wells, screw pump well, electric pump wells, fluid operated pump wells. About 50 field tests have been conducted in Huabei Oilfield, which could provide accurate information for oilfield development.
