贝克休斯公司开发的TesTrak随钻地层压力测试工具是一种新型LWD工具,可以利用钻井过程的短暂中断测量地层压力,测试时间短,一般仅需要5min即可完成一次压力测试,占用钻机时间很少。新型工具具有明显的优越性,可以用于大斜度井、水平井、大位移井,消除了工具下入困难等问题。与传统技术相比,新型随钻地层压力测试工具测量的地层压力数据能更好地反映地层的真实压力状况,据此可优化钻井工艺、提高钻井效率。
The TesTrak floor-standing stress testing tool developed by Baker Hughes is a new LWD tool that can take advantage of short interruptions in the drilling process to measure formation pressures with short test times and generally takes only 5 minutes to complete a stress test, taking up rig time less. New tools have obvious advantages, can be used for high-deviated wells, horizontal wells, large-displacement wells, eliminating the tools into the difficulties and other issues. Compared with the traditional technologies, the formation pressure data measured by the new LVDT tool can better reflect the true pressure of the formation, which can optimize the drilling technology and improve the drilling efficiency.
