Ultra-deep well drilling simulation experiment device

The invention relates to an ultra-deep well drilling simulation experiment device which mainly comprises a drilling system, an autoclave system, a rock sample heating and pressurizing system, a detecting system, a data acquiring system (22) and a computer data processing system (21). The drilling system comprises a frame, a power head system, a drilling fluid system and a hydraulic system; the autoclave system mainly comprises a dynamic sealing device (9), a pressure vessel (18), a drilling rod column (19), a bit (23), a hoop (25) and an experiment bench (29); the detecting system mainly comprises a parameter detecting system and a temperature and pressure detecting system; a programmable logic controller (PLC) is connected with the computer data processing system (21); a rock sample is put on the experiment bench (29); a resistance wire is used for heating the rock sample; a rock sample clamping and pressurizing mechanism (24) is used for pressurizing the rock sample; and the drilling system is used for drilling the rock sample. The ultra-deep well drilling simulation experiment device is used under the high-temperature and high-pressure condition.
