Gas lift Reverse Circulation drilling machinery

A gas lift reverse circulation rig injects high-pressure gas into the well through a gas compressor to create a gas column. The gas column is less dense than the formation, so it can effectively carry cuttings out of the wellhead. At the same time, the gas column can also provide the driving force to push the drill pipe to rotate the bit and achieve the role of drilling into the formation.
 Air supply preparation: Reverse circulation drilling rig needs a stable air supply. Before construction, it is necessary to check whether the connection of the air source pipeline is firm and whether the air source pressure meets the requirements. At the same time, it is necessary to ensure that the air source is clean and dry to avoid impurities or moisture entering the equipment and affecting the normal operation.
 Regular maintenance: Regular maintenance and maintenance of reverse circulation drilling rig, including cleaning equipment, replacement of lubricating oil and seals. Check the functions and components of the equipment regularly, and repair or replace the damaged parts in time.
 Construction monitoring: During the construction process, it is necessary to constantly monitor the working status of the equipment, especially the work of the air supply, exhaust system and drill pipe. Find and deal with equipment failure or abnormal situation in time to ensure the smooth progress of construction.
