Embodiment Construction

[0010] Drilling three-phase mixture automatic separation and collection device, including cyclone 1, the feed port 1-1 of cyclone 1 is arranged on the upper side wall in a tangential direction, and there is an exhaust port at the top center of cyclone 1 2. There is a filter 3 on the exhaust port 2, and a conical discharge port 1-2 with a net structure is provided at the bottom of the cyclone 1, and the end of the conical discharge port is connected to the discharge pipe 1-3. The side of the hydrocyclone 1 is provided with a vibrating screen 4, and the discharge pipe 1-3 is a bent pipe whose end stretches out from the screen of the vibrating screen 4, and the vibrating screen 4 is located on the settling tank.

[0011] The discharge pipe 1-3 is divided into two parts, the part projected on the vibrating screen 4 is a trap structure, and the part projected outside the vibrating screen 4 is an ordinary pipeline.

[0012] A fine particle solid collection box is provided at the dis...

Abstract

An automatic separation and collection device for a drilling three-phase mixture includes a cyclone, a feeding hole of the cyclone is formed in the side wall of the upper part in the tangential direction, an exhaust port is formed in the center of the top of the cyclone, a filter is arranged on the exhaust port, a conical discharge port of a screw net structure is formed in the bottom of the cyclone, the tail end of the conical discharge port is connected with a discharge pipe, a vibrating screen is arranged below the cyclone, the discharge pipe is a bent pipe with the end extending out of a screen net of the vibrating screen, and the vibrating screen is arranged on a settling pond. Compared with the prior art, a gas-liquid-solid three-phase mixture can be efficiently separated in order, continuous logging is achieved, the rock debris (sample) outlet speed can be effectively reduced, personnel and equipment safety is protected, environmental pollution caused by flying dust is avoided,meanwhile, cyclic utilization of a drilling liquid medium is achieved, and emission pollution is avoided.

Description

technical field [0001] The invention relates to a gas-liquid-solid three-phase mixture separation and collection device, in particular to an automatic drilling three-phase mixture separation and collection device for air reverse circulation drilling. Background technique [0002] At present, in the construction process of air reverse circulation drilling technology, especially in the process of drilling in complex formations, there are prominent problems in the high return velocity of the fluid, which poses a great safety hazard to the well site personnel and equipment after being discharged; cuttings logging Poor continuity and integrity; manual collection is labor-intensive, low accuracy, and the dust, debris and mud generated pollute the environment. Therefore, how to effectively separate the gas, liquid and solid three-phase mixture in an orderly manner, realize continuous mud logging, and effectively reduce the export speed of cuttings (sample), protect the safety of pe...
