200 mm Diameter Pneumatic Drilling Rig feature
It is hydraulically driven by diesel engine. The dashboard is simple and clear. It is a crawler mounted structure, which is easy to move. Steel crawler chassis is adopted (of course, you can also choose rubber crawler to facilitate walking on urban roads). Four standard high legs . When loading by car for a long transportation, you can directly get on the car without lifting.
Installation & Maintenance of 200 mm Diameter Pneumatic Drilling Rig
we can provide with the overall installation of complicated machinery,allowing you to start the normal operation of construction machinery solutions.After installation,we will make inspection of the whole machine,operate equipment,and provide you with testing data reports of installation and operation.
What should we do if meet quicksand formation?
In case of quicksand formation, the viscosity of drilling fluid must be increased and the bentonite content in the drilling fluid must be increased. Generally, it is required to be greater than 10%. A single seal is added to enhance the wall building property of the drilling fluid. In engineering, by appropriately reducing the displacement and reducing the erosion of convective sand layer, the well section must be closed with thick mud with viscosity greater than 80s before tripping out, so as to ensure the smooth running of drilling equipment and electric logging casing
