Vibrating screen drilling fluid anti-splash mechanism for desert petroleum drilling

Abstract

The invention discloses a vibrating screen drilling fluid anti-splash mechanism for desert petroleum drilling. The drilling fluid anti-splash mechanism comprises anti-splash plates and a block cover, a top plate is installed at the tops of the anti-splash plates and connected with the anti-splash plates, an anti-spray plate is arranged between the anti-splash plates and are perpendicular to the anti-splash plates, a gap exists between the bottom of the anti-spray plate and the plane where the bottoms of the anti-splash plates are located, multiple water inlet elbows are installed on the upper portion of the top plate, the bottom ends of the water inlet elbows penetrate through the top of the top plate to the portion below the top plate, the portions, located below the top plate, of the water inlet elbows are right opposite to the anti-spray plate, and a water spray head is connected to each water inlet elbow. According to the vibrating screen drilling fluid anti-splash mechanism for desert petroleum drilling, due to the fact that the anti-spray plate, the anti-splash plates and the baffle are arranged, it is guaranteed that a drilling fluid passes through a larger screen area, the use ratio of the screen is increased, the situation that solid particles move to a screen outlet under the condition of being not separated from a liquid phase is avoided, it is also guaranteed that the drilling fluid cannot splash out of the drilling fluid vibrating screen, the circulating liquid phase is reserved to the maximum extent, the use cost of the drilling fluid is reduced, and meanwhile the environment is protected.

Description

Technical field [0001] The invention relates to the field of drilling fluid vibrating screens, in particular to a vibrating screen drilling mud splash-proof mechanism used for desert drilling and oil extraction. 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 core sampling. 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 is discharged with the waste slag generated during the drilling after com...

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 anti-splash device. The solid phase particles leave the screen before being separated from the liquid phase, and take away part of the recyclable liquid phase, resulting in the loss of the recyclable liquid phase in the drilling fluid
