Drilling Work Instructions
During the working process of Crawler Mounted Air Drilling Rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling. The negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe and discharges it into the sedimentation tank through the mud pump. The circulating fluid after sedimentation continues to flow into the well, forming the reverse circulation drilling work.
Soil Layer Management
When the Crawler Mounted Air Drilling Rig encounters different geological layers during drilling, different methods should be adopted to achieve good results. For various geological layers such as quicksand layer and gypsum layer, specific approaches are required. In case of gypsum intrusion during the drilling process, calcium ion can be removed by means of soda ash, calcium removal, viscosity reduction, etc. Simultaneously, viscosity reducer with strong calcium resistance can be used to control viscosity reduction and make up for the lack of filtration loss reducer, anti-sloughing agent and other materials.
