It is understood that in accordance with the traditional drilling methods of drilling rigs, it is easy to cause blockage and borehole wall damage during the drilling process, and there is a certain potential safety hazard for the subsequent mining work. In order to solve this problem, the company has successfully developed this new type of drilling rig using the principle of gas lift reverse circulation.
According to research and development personnel, when the device is in operation, compressed air can be injected into the pipe along the annular gap of the double-walled faucet, double-wall active drill pipe, and double-walled drill pipe to form a liquid gas with a density lower than that of the liquid. In the mixture, the slurry is brought out of the hole at a high speed by a pressure difference and discharged into a sedimentation tank, and the precipitated slurry is then flowed into the hole. This cycle operation completes the drilling work, effectively saving energy and improving drilling. effectiveness. Moreover, when it is necessary to replace the sealing ring between the air intake pipe and the airtight box, it can be completed without disassembling the drill pipe drilling tool, so that the maintenance and repair work becomes more convenient and faster.
The device is suitable for construction of deep hole large bore drilling rig with diameter of 0.6 to 1.2 meters and drilling depth of less than 1000 meters, centralized gas discharge, coal mine gob area backfill and mine rescue pre-set hole construction work, and is a green low-carbon and high-efficiency drilling construction. It provided new equipment guarantees and broke traditional barriers to drilling.
Stone coal machine company innovative drilling device won the utility model patent
A new type of gas lift reverse circulation drilling device for deep bore large bore drilling rigs has been awarded a utility model patent. The device is energy saving and environmentally friendly, with high drilling efficiency, enabling continuous core sampling and judgment of rock formations. It is timely and accurate, the pipeline is not easy to be blocked, there are few drilling failures, and it can effectively protect the smoothness of the well wall and the safety of subsequent mining work. This technological innovation is also the first in the industry.
