Background

The petroleum drilling engineering is a system engineering which utilizes petroleum drilling equipment to drill a plurality of sets of stratums from the ground along a designed track to reach a preset target stratum (a hydrocarbon reservoir or a possible hydrocarbon reservoir) to form a stable channel (a hydrocarbon well) for producing or injecting required fluids (water, gas and steam), completes coring, logging and testing work during the drilling process and after the drilling is finished, and obtains various information required by exploration, development and drilling.

A large amount of drilling fluid is required during drilling. Drilling fluids are a generic term for the various circulating fluids used in the drilling process, and are also known as drilling muds. In the drilling process, the drilling fluid can effectively cool and lubricate the drill bit, can also balance the bottom pressure, avoid blowout and well kick, and besides, the drilling fluid can also transmit power and take core and sample.

The recovery of the drilling fluid is particularly important because a large amount of waste residues are mixed into the drilling fluid in the drilling process, and the high cost of the drilling fluid causes the drilling fluid to be recycled. At the present stage, a filtering mode is mainly adopted to recover the drilling fluid, but the currently used drilling fluid filtering equipment is more complicated in use and complex in operation, and meanwhile, the filtering effect of the currently used drilling fluid filtering equipment is poor and satisfactory, so that the drilling fluid which can be used cannot be obtained after a lot of working procedures are consumed.

In view of this, we propose a drilling fluid rapid filtration device.
