摘要:
松科二井是亚洲国家组织实施的最深大陆科学钻井。松科二井完钻后38 h测井温度为241℃,创造了我国钻井工程最高井温应用记录。松科二井井内参数测试主要采用两种方法,一是综合物探测井,在下套管前进行综合测井;另一种是不影响正常钻进工作,随钻进行井下参数测试。及时掌握井下随钻温度等信息,对高温泥浆性能的调整和动力机具应用起着关键性的支撑作用。本文针对松科二井科学钻探高温难点问题展开系列研究,研制了一种存储式井下高温测试仪器。该仪器经过多轮攻关改进设计,成功应用于松科二井现场,在现场应用的最高随钻测试温度为222℃。

Abstract:
Well Songke-2 is the deepest continental scientific drilling carried out by Asian countries. The logging temperature of Well Songke-2 Songke-2 was 241℃ after drilling for 38 hours, which created the highest well temperature application record of drilling engineering in China. The parameters of Well Songke-2 are mainly tested in two ways:one is integrated logging before casing, whereas the other is downhole parameter measurement while drilling which does not affect normal drilling work. Timely grasping the information such as the temperature while drilling plays a key supporting role in the adjustment of high temperature mud performance and the application of power tools. The authors carried out a series of researches on the problem of high temperature in Well Songke-2, and developed a storage type measurement while drilling instrument. The instrument was improved and designed through multiple rounds of research and finally it has been successfully applied to Well Songke-2.
