Abstract

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.

Description

Technical field: [0001] The invention relates to an ultra-deep well drilling simulation experiment device. Background technique: [0002] With the urgent demand of human beings for energy, the area of ​​oil, gas and mineral development continues to expand, from shallow wells within 1000m to the current deep wells above 4500m and ultra-deep wells above 6000m, the drilling depth is getting deeper and deeper, and the difficulty of drilling getting bigger. Due to the characteristics of high temperature and high pressure in deep wells and ultra-deep wells, the drilling process is very different from shallow drilling. Drilling simulation experiments are usually used in the laboratory to simulate the actual drilling process, test various parameters of the drilling process, and realize performance testing and evaluation of drilling tools, drill bits, drilling technology, rock samples, drilling fluid, etc., through Statistics and analysis of the relationship between various paramet...
