Abstract

The invention discloses a multifunctional deep geothermal resource drilling and well completion experiment device. The multifunctional deep geothermal resource drilling and well completion experimentdevice comprises a lifting platform and two supports arranged on the two sides of the lifting platform. The two supports penetrate through the lifting platform and are vertically connected with the lifting platform in a sliding mode. Two sets of lifting structures are arranged on the two sides of the lower portion of the lifting platform and are connected with the supports on the two sides respectively. A rotary drilling assembly connected with the lifting structures is installed in the center of the lower portion of the lifting platform, and the rotary drilling assembly rotates when the lifting structures drive the lifting platform to descend along the supports. When a drill rod drills to a hard part, although the lifting structures still drive the drill rod to extend downwards for feeding, sliding rods slide upwards to compress pressure springs to drive the drill rod to reduce the feeding amount, and the drill rod is prevented from being damaged by forced drilling; and when the drillrod drills to a part with low hardness, the compressed pressure springs can increase the feeding amount of the drill rod through resetting.

Description

technical field [0001] The invention relates to the technical field of energy exploitation, in particular to a multifunctional deep geothermal resource drilling and completion experiment device. Background technique [0002] Accelerating the efficient development and utilization of geothermal resources such as medium-deep and hot dry rocks is of great significance to improving the strategic layout of energy, optimizing the energy structure and promoting transformation and development. [0003] The prior art discloses a drilling and completion experiment device for deep geothermal resources, which uses two motors, a lifting motor and a drilling motor, and cooperates with a pressure sensor and a data acquisition and control system to realize drilling feed control. [0004] The realization of this scheme requires the help of multiple components and devices, including two motors, sensors, and data acquisition and control systems. In actual application, due to the complex and cha...
