The invention relates to the technical field of solid-liquid separation devices for waste, and is an integrated device for chemical flocculation and mechanical extrusion treatment of waste drilling fluid, which includes a buried tank, a dosing tank, a flocculation settling tank, a buffer tank and a filter press. The outlet of the buried tank and the outlet of the dosing tank are respectively connected with the inlet of the flocculation settling tank through pipelines; the clear water outlet of the flocculation settling tank is connected with the inlet of the buffer tank through pipelines; the floc outlet of the flocculation settling tank is connected with the pressure filter The inlet of the filter press is connected; the liquid phase outlet of the filter press is connected with the inlet of the buried tank. The invention has a reasonable and compact structure and is easy to use. It is suitable for the treatment of solid-liquid waste in low-density and low-solid-phase drilling fluids while drilling without falling to the ground. The solid-liquid separation effect is good, the use cost is low, and it is convenient for field installation. Scenes.
Description
technical field [0001] The invention relates to the technical field of waste solid-liquid separation devices, and is an integrated device for chemical flocculation and mechanical extrusion processing waste drilling fluid. Background technique [0002] At present, for gas fields with special formation conditions, a set of clear water polymer drilling fluid system has been formed. This system has the characteristics of low density and low solid phase content. Generally, the drilling fluid density is controlled at 1.0g / cm 3 to 1.05g / cm 3 , the viscosity is about 30s, adopting the method of digging the waste liquid pool, without going through the drilling fluid circulation tank and solid control equipment, the natural settlement method of discharging the waste liquid from one end of the waste liquid pool and extracting from the other end can realize rapid and safe drilling. With the promulgation and implementation of the new "Environmental Protection Law", the gas field compreh...
