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.
