Abstract

A system capable of disposing drilling waste materials in the drilling process and allowing the drilling waste materials not to fall on the ground is characterized in that a vibrating screen serves as the first layer, a desander serves as the second layer, and a centrifuge serves as the third layer; a rock debris collecting device B is arranged on one side of the vibrating screen and communicated with a drying device through a pipeline, and a rock debris conveyor used for discharging sand is arranged on one side of the drying device; one side of the desander and one side of the centrifuge are provided with a rock debris collecting device A, a conveying device is arranged between the rock debris collecting device A and a gel breaking and flocculation reaction tank, the gel breaking and flocculation reaction tank is communicated with a chemical dosing device and a box type membrane filter press through pipelines, and a pipeline used for discharging filter cakes and filtrate is arranged on one side of the box type membrane filter press. The system has the advantages that the waste materials in the drilling process can be disposed timely in the drilling process, so that the requirement for 'no falling to the ground' is satisfied, thereby realizing clean production in a well field and achieving the environmental protection goal of 'zero emission' for well drilling.

Description

A kind of Discarded Drilling Materials thing does not land with boring treatment system
Technical field
The utility model relates to a kind of Discarded Drilling Materials thing and does not land with boring treatment system, belongs to the prevent and remedy pollution technology of aspect of oil field geologic drilling well.
Background technology
At present, known Discarded Drilling Materials thing treatment system, that Discarded Drilling Materials thing is concentrated and is placed in a Discarded Drilling Materials thing pond, open after excavator is put medicine stirring in Discarded Drilling Materials thing pond it is solidified from operating personnel, Discarded Drilling Materials thing pond after solidifying is filled and led up and just can be used further to cultivate, the drawback of its conventional method is, Discarded Drilling Materials thing is concentrated and is placed in a Discarded Drilling Materials thing pond, floor space is large, Discarded Drilling Materials thing pond pollutes farmland around well site and water source, has wasted national available land and has affected and cultivated.Meet rainy season or flood season, likely excessive inflow farmland, river or permeate the ground of the rejected well drilling liquid in Discarded Drilling Materials thing pond, the hazardous substances in drilling fluid produces and has a strong impact on soil, underground water and local natural environment.
Summary of the invention
The purpose of this utility model is, provides a kind of Discarded Drilling Materials thing not land with boring treatment system.
A kind of Discarded Drilling Materials thing does not land with boring treatment system, it is characterized in that, described vibrosieve (1) is first floor, and desander (2) is the second layer, and centrifuge (3) is the 3rd layer; Be provided with landwaste gathering-device B (5) in a side of vibrosieve (1), described landwaste gathering-device B (5) and desiccation apparatus (12) pipeline communication, be provided with the landwaste conveyer (13) of discharging sand (14) in a side of desiccation apparatus (12);
A side at described desander (2) and centrifuge (3) is provided with landwaste gathering-device A (4), between landwaste gathering-device A (4) and broken glue flocculation reaction tank (15), be provided with conveying device (6), described broken glue flocculation reaction tank (15) and chemicals dosing plant (7) pipeline communication, broken glue flocculation reaction tank (15) and box diaphragm filter press (8) pipeline communication, be provided with the pipeline of discharging filter cake (9) and filtrate (10) in a side of box diaphragm filter press (8).
The utlity model has 6 large advantages: 1. the discarded object in drilling process, can process with boring in time, reach " not landing " requirement.Realize well site and cleaned production, reached the environmental objective of drilling well " zero-emission "; 2. drilling wastes, with boring treatment system, is that " process processing " and " terminal processes " united two into one; 3. well site does not need to dig and builds mud pit, has reduced the environment pollution of drilling well refuse, has reduced yet and has bored front construction and cost of floor space; 4. by specific aim dosing, broken glue, flocculation, Separation of Solid and Liquid is thorough, filtration cakes torrefaction, and filtrate clarification, limpid filtrate reaches discharging standards, in drilling process, can reuse, and can be used for system re-injection through advanced treating; 5. the moisture content of the cake after box diaphragm filter press squeezing can be controlled in 20%, dry, hard, hazardous substances in solidfied material cannot be dissociated, realize innoxious, also can provide cheap raw material for brick field, haydite factory simultaneously, fire through 1200 degree high temperature refinery, realize the solid portion of oilfield drilling discarded object harmless treatment, turn waste into wealth; 6. skid-mounted type design, is convenient to, with boring resettlement, adapt to the mobility industry characteristic of oil field prospecting drillng operation.
Accompanying drawing explanation
Fig. 1 is process flow diagram of the present utility model.
In figure: 1 vibrosieve, 2 desanders, 3 centrifuges, 4 landwaste gathering-device A, 5 landwaste gathering-device B6 conveying devices, 7 chemicals dosing plants, 8 box diaphragm filter press, 9 mud cakes, 10 filtrates, 11 dosing cleaning devices, 12 desiccation apparatus, 13 landwaste conveyers, 14 sands, 15 broken glue flocculation reaction tanks.
The specific embodiment
As shown in Figure 1, vibrosieve 1 is first floor, and desander 2 is the second layer, and centrifuge 3 is the 3rd layer, and Discarded Drilling Materials thing enters in vibrosieve 1 by drilling equipment, and vibrosieve 1 leaves oarse-grained Discarded Drilling Materials thing, and tiny Discarded Drilling Materials thing enters in desander 2.
Be provided with landwaste gathering-device B5 in a side of vibrosieve 1, vibrosieve 1 bulky grain out enters in dosing cleaning device 11 by landwaste gathering-device B5, hazardous substances dosing on bulky grain is cleaned, then be delivered in desiccation apparatus 12 by pump, after desiccation apparatus 12 mummification, become sand 14, then discharged by landwaste conveyer 13.
Be provided with landwaste gathering-device A4 in a side of described desander 2 and centrifuge 3, the particle that desander 2 filters out enters landwaste gathering-device A4, after centrifuge 3 High Rotation Speeds, accelerate particle sinking speed in Discarded Drilling Materials thing and enter landwaste gathering-device A4, Discarded Drilling Materials thing in landwaste gathering-device A4 arrives in broken glue flocculation reaction tank 15 by conveying device 6, the medicine of chemicals dosing plant 7 interior placements is delivered to brokenly in glue flocculation reaction tank 15 by pump, evenly mixes with Discarded Drilling Materials thing.Reacted Discarded Drilling Materials thing is delivered in box diaphragm filter press 8 by pump, and described box diaphragm filter press 8 is mainly by Separation of Solid and Liquid, and the solid filter cake 9 of separating, by the direct entrucking outward transport of lift-type belt conveyor or place mat well site; Clear filtrate 10 irrigation up to standard of separating or be pumped back to drilling crew use.
Described box diaphragm filter press 8 is mainly that mud cake is carried out to barrier film, squeezing, its principle is: in several filter plates of common filter press, add a barrier film hollowcore slab every a filter plate, complete after press filtration operation, pressurize to filling liquid in barrier film hollowcore slab, make the expansion of barrier film hollowcore slab, thereby make extruding mutually between plate and plate, by outside water injection pressure pump controlled pressure size, meanwhile, carry out squeezing program, hydraulic means is set up in one end at common filter press, mud cake in the middle of pressured squeezing external force extruding filter plate and barrier film hollowcore slab, thereby further squeeze the moisture content in mud cake.
