Abstract
A physical simulation and calibration device and method for formation pressure testing. The device has a rock core arranged in a rock core clamper, a confining pressure simulation module, formation pressure simulation module, annular pressure simulation module, suction system, thrust force simulation module and drive control system. The thrust force simulation module has a thrust rod which penetrates through a cavity wall on one side of the clamper. The front end of the thrust rod has a simulation probe. The suction system is connected to the thrust rod. The confining pressure simulation module, formation pressure simulation module, annular pressure simulation module, thrust force simulation module and suction system are all connected with the drive control system. The device and method simulate a physical environment of formation pressure testing to achieve physical simulation of formation pressure testing. A formation pressure tester can be corrected and calibrated.
