Description

Multifunctional slurry collecting device

Technical Field

The utility model relates to a shale shaker technical field, in particular to multi-functional mud collection device.

Background

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.

At present, drilling muds used by the drilling crew are mainly water-based muds and oil-based muds. The water-based mud is also called water-based drilling fluid, has lower manufacturing cost, large solid content of mud, quick deposition and low requirement on the dryness of drill cuttings, and can realize the screening of the mud by using a conventional vibrating screen. The oil-based mud is also called oil-based drilling fluid, the manufacturing cost is high, the solid phase content of the mud is small, if the conventional vibrating screen is used for screening, screened solid phase particles do not reach the standard and cannot be directly discharged outside, and the oil-based mud needs to be further processed; in addition, the liquid phase after sieving is easy to run off along with the solid phase. Therefore, most of the oil-based mud is screened by using the vacuum adsorption screen, and the screened solid phase can reach the standard and be discharged outside by using the vacuum adsorption function, so that the screening efficiency is improved, more liquid-phase mud is screened, and the cost is saved. The operating costs are greatly increased if water-based muds are also treated using vacuum adsorption screens, and thus, existing drilling teams use conventional vibrating screens for water-based muds and vacuum adsorption screens for oil-based muds. The existing slurry treatment equipment is high in investment cost, large in occupied area and not suitable for places with small well site areas, equipment needs to be frequently carried, and the labor intensity of field workers is increased.

The normal-pressure slurry discharge port is arranged at the rear part of the vacuum collecting hopper, so that slurry is discharged completely without accumulation, and the sieve box is stable in structure. If the normal-pressure slurry discharge port is arranged at the side part of the vacuum collection hopper, the normal-pressure slurry discharge port deflects when the vibrating screen works, so that the screen box vibrates left and right, and the screen box is cracked due to shaking; if the normal-pressure slurry discharge port is arranged at the front part, the vibrating screen is placed at a positive angle, namely the design of high front part and low back part, the liquid level height of the slurry discharge port is increased, and the liquid level is accumulated.

Further, the utility model discloses still including the sealed closure plate that is used for the shutoff to arrange the thick liquid mouth through vacuum or ordinary pressure, the connection can be dismantled on the vacuum collection fill to sealed closure plate. The vacuum slurry outlet or the normal pressure slurry outlet can be conveniently plugged through the plugging plate.
