Abstract

The invention discloses a solid control processing device and a processing method capable of preventing mud from falling to the ground, and relates to the technical field of solid control of waste mud. A solid phase outlet of a vibrating screen is connected to a drilling cuttings spin-drier through a screw conveyer; liquid phase outlets of the vibrating screen and the drilling cuttings spin-drierare connected with a No. 1 mud tank; the No. 1 mud tank is connected with a vacuum degasser; the vacuum degasser is connected with a grit separator through a No. 2 mud tank; a liquid phase outlet of the grit separator is connected with an inlet of a desilter through a No. 3 mud tank; a liquid phase outlet of the desilter is connected with an inlet of a centrifugal machine through a No. 4 mud tank;and a liquid phase outlet of the centrifugal machine is connected to an inlet of a No. 5 mud tank. Solid phase outlets of the drilling cuttings spin-drier, the grit separator, the desilter and the centrifugal machine are separately connected with a solid phase collecting box. The solid control processing device and the processing method capable of preventing mud from falling to the ground have the beneficial effects that the mud with a large amount of drilling cuttings can be subjected to multi-stage processing; the solid phase can be removed from large particles to small particles in sequence; the treatment efficiency is high; equipment can be effectively protected; and the solid phase particles of the mud processed by the device and the method are less than 5 mu m.

Description

technical field [0001] The invention relates to the technical field of solid control of waste mud produced by drilling, in particular to a solid control treatment device and a treatment method for mud not falling to the ground. Background technique [0002] In drilling engineering, mud is usually synonymous with drilling fluid. Mud was used in drilling in 1901. At that time, the Hamill brothers in the United States were drilling at the "Spindle Top" in Texas to find oil. In order to deal with difficulties such as sand layers during the drilling process, they used mud to reinforce and support the drilling wall. This practice has been used to this day. At that time, mud refers to ordinary mud, and the mud used in modern engineering is actually synthetic mud. Mud usually contains a large amount of suspended matter, colloidal water, oil or a mixture of oil and water. The mud has the functions of suspending cuttings and carrying them from the bottom of the well to the surface,...
