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.

Abstract: The present disclosure discloses an experimental apparatus and method for simulating transport of a sand-carrying fluid in a fracturing fracture. The apparatus may include a spiral proppant transport device, a stirred tank, a screw pump, a liquid transport pump, a pressure gauge, a proppant transport and distribution system, a cyclone desander, a waste liquid recycle container, a proppant recycle container, and a fracturing fluid tank. The spiral proppant transport device may be communicated with the stirred tank. The waste liquid recycle container and the fracturing fluid tank may be communicated with the stirred tank via the liquid transport pump. A bottom end of the stirred tank may be communicated with the proppant transport and distribution system through the screw pump. It is possible to simulate the sand-carrying fluid paved under a closure pressure by setting a computer to precisely control a transparent cuboid fracture member including hydraulic tanks.

Abstract: The present invention relates to a multi-functional drilling experiment platform, which consists of a gantry, a hydraulic cylinder, a power swivel and a platform base. The gantry mainly realizes the control of the drill string during the drilling-in process. In order to simulate the vertical well, the inclined well, and the horizontal well, the drilling machine needs to rotate between 0° and 90°. The rotation of the gantry is realized by the extension and contraction of the hydraulic cylinder. The platform base is used to set up the gantry and the hydraulic cylinder, bearing the pulling, pressing and twisting loads of drilling experiments. Also, the platform base can move along the track to achieve different types of experiments. The multi-functional drilling experiment platform of the present invention realizes the load simulation experiment of the drilling machine at different angles using the gantry and the hydraulic cylinder.
