Abstract

The invention discloses a solid control system applied to a desert oil drilling process. The solid control system applied to the desert oil drilling process comprises a sieving box, a vibration motor, a supporting plate and a blowout prevention device. A feeding opening is formed in the position above one end of the sieving box, the other end of the sieving box is provided with a solid phase discharging opening, the sieving box is internally provided with a screen cloth frame, the screen cloth frame is internally provided with screen cloth, a liquid phase discharging box communicated with the sieving box is arranged below the solid phase discharging opening, the bottom of the liquid phase discharging box is provided with a liquid phase discharging opening, the side face of the liquid phase discharging box is connected with an exhaust column, the exhaust column is connected with an exhaust fan, and a plurality of spring baffle devices are arranged on the screen cloth frame at equal intervals in the direction from the feeding opening to the solid phase discharging opening. By means of the solid control system, after drilling fluid knocks the screen cloth, the liquid phase separated from solid phase particles enters the position below the screen cloth more easily, the screen cloth cannot be blocked, the handling capacity of a drilling fluid vibrating screen to the drilling fluid is increased, knock impulsive force generated when the drilling liquid knocks the screen cloth is increased, and the solid phase particles can 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 solid control system applied to the desert oil drilling process. 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. Bec...
