Research and Application on Test System of High Temperature and Pressure Underground.Wells
摘要
Abstract
In order to develop a test system of the parameters of high temperature and pressure underground wells, Platinum resistance and Si-sapphire are used as sensor of front-end. The way of directly measurement is used by this system to a-void conduction between medium so that decrease the error. It is stable in sampling the signal of front-end driven by constant-current source. Sampled signals are relation with depth by the way of synchronization in time, and the curve of temperature and pressure can be draw as the variations of depth on wells when analyzing the data. The rules of stratum distribution are mastered with the accurate measurement.关键词
