Information such as speed, heading, GPS difference equipment can also be the vehicle of various sensors (such as log, speed meter, magnetic compass, etc.) for the calibration work.
Calibration of pressure system is the precondition of formation tester log.
压力系统的刻度是地层测试器测井的前提。

The variation of CHGR with depth is available from the calibration of the porosity, gas saturation of electric log interpretation of the reservoir and hydrocarbon gases expansion coefficient.
