注水井启动压力分层测试工艺

Injection Well Starting Pressure Multiple-Layered Test Technology

为清楚认识注水井各层段的启动压力和吸水指数,提高分层注水效果。针对目前油田中测试工艺存在的问题,研制了注水井启动压力分层测试工艺。本文介绍了管柱结构,使用方法、选井条件以及主要的配套工具。通过现场应用表明,该工艺较好地解决了启动压力分层测试问题,见到了良好的增油效果,为油田分层措施提供了可靠依据。

To make clear the starting pressure and water absorption index of injection well at different stage for the improvement of high stratified water injecting effect. Basing on the problems in the current oil field testing technology, injection well starting pressure multiple-layered test technology is developed. The paper introduces the tubular column structure, usage methods, well selection condition and main assembly tools. Field application shows that the proposed technology the problem of starting pressure multiple-layered test and good effect for enhancing oil production is obtained through the tests and some reliable data for oil field stratification measurement is provided.
