The testing of the pressure, temperature and inclination is very critical in China Continental Scientific Drilling （CCSD）. Combined with the pre-researched project of CCSD, this paper studies the technical difficulties of designing the down-hole instrument, analyses the testing circumstances and expounds the significance of the testing of these parameters. Using the method of Measuring While Drilling and the testing means of storing the information in the down-hole and playing it back on the surface, we develop the measure system that measures the parameters in the hole cooperating with the wire-line coring. The system based on the first system can work stably with using high-performance, lowenergy consuming chip, and can measure the parameters of the vertex angle, temperature and pressure in the course of the salvaging lance＇s working.
