Abstract
The invention relates to equipment and a method for treating drilling fluid waste, in particular to equipment and a method for spin-drying treatment of oil-based drilling fluid waste. The oil-based drilling fluid waste spin-drying treatment technology adopts a spin-drying machine to spin-dry oil-based drilling cuttings and waste (the oil content is 10% -30%) so that the oil content is reduced to be below 5% (the oil-containing drilling cuttings can be directly baked into bricks or paved with roads), and then a high-speed centrifuge is used for carrying out solid-liquid separation on a liquid phase thrown out by the spin-drying machine, so that a pure oil product is recovered and reused. On one hand, the problem of waste pollution of the oil-based drilling fluid is well solved, and on the other hand, the waste of the oil-based drilling fluid or the synthetic base is reduced.
Description
Technical field
The present invention relates to a kind of drilling fluid discarded object and dry treatment facility and method, particularly the oil base drilling fluid discarded object dries treatment facility and method.
Background technology
In the wellbore construction process, produce a large amount of drilling cuttings and discarded object, because these drilling cuttings and discarded object are subject to the pollution of drilling fluid and formation fluid, oil content in drilling cuttings and the discarded object is higher, the highest above 30%, the producible drilling cuttings of a bite well and discarded object can reach hectostere, and plant does not give birth to, biological death, can bring disaster at last we mankind's existence.Therefore oil-base mud drilling cuttings and discarded object being made the needs that harmless treatment is environmental protection, also is the needs of our human survival.Discharging can be polluted surrounding environment arbitrarily, and the earth of depending on for existence to us causes the injury that can't recover, and progressively dwindles the space of human survival.Therefore to could discharge through harmless treatment drilling cuttings and the discarded object that produces in the drilling process.Because the natural degradation of oil base drilling fluid discarded object is unusually difficult, the difficulty of artificial treatment is also quite large simultaneously, and the harmless treatment of thing followed oil base drilling fluid discarded object becomes the bottleneck problem of promoting the use of oil base drilling fluid.At present, be first through mechanical pretreatment to the more feasible method of disposal of oily sludge, then to carry out a biological disposal upon, its advantage is to process thoroughly, but relatively poor to the disposal of oily sludge effect of low granularity, and can not reclaim waste oil.
Summary of the invention
The purpose of this invention is to provide a kind of oil base drilling fluid discarded object and dry treatment facility and method.Oil base drilling fluid discarded object of the present invention dries treatment technology, with drier oil base drilling cuttings and discarded object (oil content 10%--30%) are dried, make oil content be reduced to (such oil-contained drilling cuttings can directly be baked bricks or pave the way) below 5%, with supercentrifuge the liquid phase that drier throws away is carried out Separation of Solid and Liquid again, reclaim pure oil product recycling.Solve well on the one hand the problem of oil base drilling fluid waste pollution, also reduced on the other hand the waste of oil base drilling fluid oil or synthetic base.
Technical scheme of the present invention is as follows:
A kind of oil base drilling fluid discarded object dries treatment facility, mainly formed by landwaste collecting box, excavator, overhead dump skip, auger conveyor, drier, drilling cuttings collecting box, centrifuge, liquid phase collecting tank etc., placing a shaftless auger conveyor under the overhead dump skip discharging opening is connected with the drier entrance, place one under the drier sediment ejection opening axle auger conveyor is arranged, there is axle auger conveyor discharge end to be arranged on drilling cuttings collecting box top, the drier leakage fluid dram is connected with the liquid phase collecting box, and the liquid phase collecting box is connected by screw pump with supercentrifuge.
Described drier is mainly by loam cake, rotor, charging aperture, cloth tray, motor, belt, differential mechanism, sediment ejection opening, base, leakage fluid dram, scraper, basket forms, drier top is loam cake, the loam cake center is provided with charging aperture, it is cloth tray under the charging aperture, cloth tray is connected with trapezoidal rotor, on the dual-side of rotor scraper is installed, be provided with basket from the charging aperture bottom to the rotor bottom outrigger, form cavity between rotor and the basket and be used for holding discarded object to be dried, form cavity between loam cake and the basket and be used for holding the filtrate that throws away, and discharge through the leakage fluid dram of cavity bottom, rotor is connected with turning cylinder, and turning cylinder is fixed on the base, and the filtrate base is provided with sediment ejection opening, turning cylinder is connected with differential bearing, and differential mechanism is connected by belt with motor.
A kind of drilling fluid refuse processing method may further comprise the steps:
1) the drilling fluid discarded object through vibrosieve from after, a part (liquid phase+solid phase) flows into drilling fluid tank, treats that solid control equipment further separates, a part (containing useless solid phase) enters the landwaste collecting box;
2) after the landwaste collection of landwaste collecting box is full, with excavator the landwaste dress is delivered in the overhead dump skip;
3) by overhead dump skip landwaste is discharged into the input auger conveyor, by the input auger conveyor landwaste is evenly sent into drier;
4) after landwaste enters drier, the solid phase of separating enters the output auger conveyor and sends into drilling cuttings collecting box wait utilization (bake bricks or pave the way), the liquid phase of separating enters the liquid phase collecting tank, after the liquid phase collecting tank is filled, is transported to supercentrifuge with screw pump;
5) after supercentrifuge separates, the solid phase products for further is processed, and liquid phase is back to drilling fluid tank, cycling and reutilization.
The invention has the beneficial effects as follows:
1, to the environmental protection important breakthrough, oil base drilling fluid drillings and discarded object harmless treatment equipment can be reduced to drilling cuttings and the discarded object of oil content below 30% below 5%, can recycle, and directly bake bricks or pave the way.
2, reclaim the recycling of oil plant, reduce cost, save the energy, the drilling cuttings oil content is on average calculated by 15%, processes 1m
3Drilling cuttings can reclaim the 100kg-200kg oil product.
3, dwindle floor space in the drilling well production process, oil base drilling fluid drillings and discarded object harmless treatment equipment adopt integrated assembling, and all devices is integrated being assembled on the sled all, and floor space is 30m only
2, simultaneously with oil base drilling fluid drillings and discarded object harmless treatment device processes drilling cuttings and discarded object, need not dig the blowdown hole, the floor space that can save nearly hundred recipe rice.
4, energy-conservation, this device total electricity consumption, consumes energy minimum in all waste thing treating apparatus less than 40kw.
