Gas lift rig system Reverse circulation Drilling Machine

A gas lift drilling rig system is a drilling rig that uses gas lift technology to circulate drilling fluid during drilling. 

The system uses gas injection into the drilling fluid to create a reverse circulation, allowing fluid to flow from the bottom of 

the wellbore to the surface.

The Gas Lift Rig System consists of several parts, including gas injection system, drilling fluid circulation system and 

control system. The gas injection system usually includes a gas compressor, a gas injection valve and a gas lift cylinder. 

The compressor provides high pressure gas, which is injected into the drilling fluid through the gas lift valve and the core barrel.

The drilling fluid circulation system includes mud pump, drill string and drill bit. The mud pump pumps the drilling fluid down

 the drill string and out through the bit. The gas injection creates a reverse circulation in which drilling fluid flows up the annulus

 between the drill string and the well wall, bringing cuttings and other debris to the surface.

The control system of gas lift drilling rig system is responsible for monitoring and controlling parameters such as 

gas injection volume and drilling fluid flow. It ensures an efficient and safe drilling process.

In general, a gas lift rig system with a reverse circulation rig has many advantages over conventional drilling methods.

 It improves drilling efficiency, reduces the risk of sticking, minimizes formation damage, and improves safety by

 reducing drillers' contact with drilling fluid.
