Gas Lift Reverse Circulation Rig Drilling Machine 

Gas lift reverse circulation drilling rig is a kind of drilling equipment used in oil and gas industry. It is designed to drill through a combination of gas lift and reverse circulation technology. Gas lift is a method of artificial lifting that uses compressed gas to lift fluid from the wellbore to the surface. In drilling operations, gas lift is used to remove drilling fluid (commonly known as mud) from the wellbore during drilling. This helps prevent drilling fluids from clogging the wellbore and improves visibility and control of drilling operations. Reverse circulation, on the other hand, is a technique that pumps drilling fluid into the drill string and out through the bit. The fluid then flows up the annulus (the space between the drill string and the wellbore) and collects at the surface. This method is often used in drilling operations where the formation being drilled is prone to caving or collapse. The gas-lift reverse circulation rig combines these two technolog…
