Abstract
The utility model relates to a self-recycling well cleanout truck for the injection well of the oilfield connecting with the well head through the high pressure hose quick changing coupler on the truck. The return water at the well head firstly enters into the two-pole eddying flow desander through pressure gauge, flowmeter, safety valve of the water inlet pipes assembly, and then enters into inclined tube oil remover (8), walnut shell filter (10), modified fiber ball filter(9), and finally enters into cleaning water tank (7), with pressure returning to the normal. The water in the cleaning water tank is supplied to three cylinder plunger pump (4) for pressurizing through the pipelines, and then will be injected into the injection well through pressure gauge, flowmeter, safety valve of the water outlet pipes assembly, forming self self-recycling well cleanout operation. The truck being used in the oilfield exploitation can improve the water quality, save water source, reduce formation jamming, water injection pressure, and increase water injection volume, thereby realizing stable and large production of the oilfield and preventing the environmental pollution.
Description
Technical field
The utility model belongs to in-vehicle water injection well in oil fields oil-contained waste water treatment device.
Background technology
There was technical problem underlying in the well-flushing car in the past: the first, do not have gear shift, speed-changing mechanism in the driving system, cause high pressure well-flushing pump can not have enough well-flushing pressure well to be washed logical; The second, on technical design, do not examine and filter the dirt of removing the well-flushing and in time get rid of, thereby can not guarantee the continuous dirt-removing power of each container handling, make the water quality after the processing not up to standard.Three, the inclined tube oil remover with the bigger oil of volume, gas, water, four separation of mud replaces the mono-oil water separator, and the scrubbing of well-flushing car, water environment capacity are significantly strengthened; Four, filter adopts the state-of-the-art modified fiber ball filter of present domestic technique as precision filter, and suspended matter is reached below the 5mg/L, and oil-containing reaches below the 3mg/L, thereby satisfies the well-flushing needs of hyposmosis well.
Summary of the invention
