Drilling fluid regeneration device

Abstract

The invention discloses a drilling fluid regenerating device. The drilling fluid regenerating device comprises a sieve box, a vibration motor, a supporting plate, a baffle cover and a blowout preventer. A feeding port is formed in the upper portion of one end of the sieve box, a solid-phase discharging port is formed in the other end, the sieve box is internally provided with a screen cloth frame, and the screen cloth frame is internally provided with screen cloth. A liquid-phase discharging box communicated with the sieve box is arranged below the solid-phase discharging port, a liquid-phase discharging port is formed in the bottom of the liquid-phase discharging box, the side face of the liquid-phase discharging box is connected with an exhaust tube, and the exhaust tube is connected with an exhaust fan. After drilling fluid impacts on the screen cloth, liquid phase disengaging from solid-phase particles can enter the part below the screen cloth more easily and will not block the screen cloth, the handling capacity of a drilling fluid vibration sieve to the drilling fluid is increased, and airflow can increase the impacting force when the drilling fluid impacts on the screen cloth to enable the solid-phase particles to be separated from the liquid phase more easily.

Description

technical field [0001] The invention relates to the field of drilling fluid recovery, in particular to a drilling fluid regeneration device. Background technique [0002] Drilling fluid is a general term for various circulating fluids used in the drilling process, and drilling fluid is also called drilling mud. During the drilling process, the drilling fluid can effectively cool and lubricate the drill bit, and can also balance the underlying pressure to avoid blowout and kick. In addition, the drilling fluid can also transmit power and take coring samples. According to different dispersion media, drilling fluids are mainly divided into three categories: water-based drilling fluids, oil-based drilling fluids and gas-based drilling fluids. [0003] During the drilling process, the drilling fluid enters the bottom layer through the drill pipe, and after completing its function, it is discharged together with the slag generated in the drilling. Because the drilling fluid is no...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is aimed at the shortcomings of the traditional drilling fluid shale shaker, and the purpose is to provide a drilling fluid regeneration device to solve the problem that the drilling fluid is easy to remain in the sieve holes on the screen during the screening process of the traditional drilling fluid shale shaker. Loss of recoverable liquid phase in the fluid, reduction of drilling fluid shale shaker throughput and easy damage to the screen
