Product Description
Gas-lift reverse circulation drilling technology is due to large backflow, fast backflow, high drilling efficiency, high drilling efficiency, long bit life, and good well quality. Drilling in complex formations is safe and reliable. Continuous sampling (coring) drilling, saving auxiliary time and reducing labor intensity, has been recognized in practice. It has become the main technical means for drilling water wells, geothermal wells, gas wells, coalbed methane wells, and large-diameter projects at home and abroad, and its application scope is getting wider and wider.
