[0002] At present, the known waste drilling fluid treatment system is to centrally place the waste drilling fluid in a waste drilling pool, and the operator drives an excavator to put medicine into the waste drilling pool and make it solidify after stirring, and the cured waste The drilling pool can be used for farming after filling it up. The disadvantage of the conventional method is that the waste drilling fluid is placed in an abandoned drilling pool, which occupies a large area, and the abandoned drilling pool will pollute the farmland and water sources around the well site. , wasting land available to the country and affecting farming

Embodiment Construction
[0010] like figure 1 As shown, the vibrating screen 1, the desander 2, and the centrifuge 3 are connected through each other. The vibrating screen 1 is the first layer, the desander 2 is the second layer, and the centrifuge 3 is the third layer. Waste drilling materials pass through Drilling equipment enters the vibrating screen 1, and the vibrating screen 1 leaves the large-grained abandoned drilling materials, and the fine abandoned drilling materials enter the desander 2.
[0011] A cuttings collection device B5 is provided on one side of the vibrating screen 1, and the large particles from the vibrating screen 1 enter the dosing and cleaning device 11 through the cuttings collection device B5, so that the harmful substances on the large particles are cleaned by dosing, and then passed through The pump is transported to the HGD drying device 12, and after being dried by the HGD drying device 12, it becomes sand 14, and then discharged by the cuttings conveyor 13.

Provided is an abandoned well drilling matter disposal system with abandoned well drilling matter not falling on the ground during drilling. The abandoned well drilling matter disposal system with the abandoned well drilling matter not falling on the ground during drilling is characterized in that a vibrating screen serves as a first layer, a grit catcher serves as a second layer, a centrifugal machine serves as a third layer, the abandoned well drilling matter enters the vibrating screen through well drilling equipment, the vibrating screen keeps large-grained abandoned well drilling matter, fine abandoned well drilling matter enters the grit catcher, large grains screened out by the vibrating screen enter a dosing cleaning device through a rock debris collecting device B and are conveyed to an HGD desiccation device through a pump, and the large grains form sand through desiccation by the HGD desiccation device and are discharged through a rock debris conveyor. Particles filtered through the grit catcher enter a rock debris collecting device A, and then are conveyed into a gel breaking flocculation reaction tank through a conveying device to react. Chemicals in a chemical dosing device are conveyed into the gel breaking flocculation reaction tank through a pump, reacted abandoned well drilling matter is conveyed to a box-type diaphragm filter press through a pump, and filter cakes and filter liquid are separated through the diaphragm filter press. Moisture content of squeezed mud cakes can be controlled within 20%.
Description
technical field [0001] The invention relates to a treatment system for waste drilling objects that do not fall to the ground while drilling, and belongs to the technology of oil field geological drilling pollution prevention and control. Background technique [0002] At present, the known waste drilling fluid treatment system is to centrally place the waste drilling fluid in a waste drilling pool, and the operator drives an excavator to put medicine into the waste drilling pool and make it solidify after stirring, and the cured waste The drilling pool can be used for farming after filling it up. The disadvantage of the conventional method is that the waste drilling fluid is placed in an abandoned drilling pool, which occupies a large area, and the abandoned drilling pool will pollute the farmland and water sources around the well site. , wasting the available land of the country and affecting cultivation. During the rainy season or flood season, the waste drilling fluid in ...
