Abstract
The utility model discloses an oil-well sand washing and well cleaning truck in an oil field. In the truck, a three-cylinder pump and a sand-washing well cleaning liquid processing unit are arranged on an automobile chassis; and the truck is formed by connecting and assembling a clear water tank, a crude oil tank, a centrifugal pump, the thee-cylinder pump, a tilted-plate deoiler, a cyclone desander, a sand storage tank and a basket filter by a pipeline 2 and a pipeline in sequence on the automobile chassis along the direction of an automobile head. When in use, the truck is connected with a well mouth by a hose quick-change connector, well-mouth pressure returning fluid enters the basket filter, the cyclone desander and the tilted-plate deoiler sequentially and then enters the clear water tank, at the moment, the pressure is recovered to be normal; after the water in the clear water tank is delivered to the three-cylinder pump for pressure boost, the water is poured into the well, so as to form circulated sand washing and well cleaning.
Description
Affiliated technical field
The utility model relates to a kind of environmental protection equipment of oilfield operation, and particularly a kind of oilfield sand-flushing car that is used for the sand washing operation is applicable to the operation of oilfield sand-flushing.
Background technology
At present, the existing typical process flow of Sand-washing in Oilfield clean-out service is: former water-tank lorry → 400 type cementing truck → oil pipes → sleeve pipe → circulating sewage jar → cementing truck → oil pipe circular treatment.This treatment process exists: 1) dead oil in oil, the sleeve pipe can not in time reclaim; 2) can cause crude oil, sewage to land, can not satisfy the environmental requirement of increasingly stringent; 3) treatment effect of oil, suspension, sand is undesirable, and well washing effect is poor; 4) it is more to take equipment, the execute-in-place inconvenience.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of oilfield sand-flushing car that improves oil, water, sand separation effect, not only improves oil, water, sand separation effect, and reduces coordinating operation equipment.
The technical solution that the utility model is taked is: on automobile chassis, along the headstock direction, be assembled into one and form by be linked in sequence filtered water tank, former fuel tank, centrifugal pump, three cylinder pump, swash plate oil expeller, hydrocyclone, sand reservoir box, basket filter of pipeline 2 and pipeline.Oilfield sand-flushing car owner will comprise that three cylinder pump, sand-flushing liquid processing device all place on the known automobile chassis.The sand-flushing liquid processing device is made up of processing unit such as two basket filters in parallel, two hydrocyclones in parallel, swash plate oil expeller and filtered water tank, former fuel tank, sand reservoir box, centrifugal pump, and each processing unit links to each other by manifold.
The beneficial effects of the utility model are to improve the operation of oilfield sand-flushing, the minimizing environment pollution.
Description of drawings
Below, in conjunction with the accompanying drawings structure of the present utility model and operating principle are further described.
Fig. 1 is a structural representation vertical view of the present utility model.
Fig. 2 is a structural representation front view of the present utility model.
Accompanying drawing number is: 1, automobile chassis, 2, filtered water tank, 3, three cylinder pump, 4, the swash plate oil expeller, 5, hydrocyclone, 6, basket filter, 7, sand reservoir box, 8, pipeline, 9, pipeline 2,10, centrifugal pump, 11, former fuel tank.
The specific embodiment
See figures.1.and.2, on automobile chassis (1), along the headstock direction, be assembled into one and form by be linked in sequence filtered water tank (2), former fuel tank (11), centrifugal pump (10), three cylinder pump (3), swash plate oil expeller (4), hydrocyclone (5), sand reservoir box (7), basket filter (6) of pipeline 2 (9) and pipeline (8).Oilfield sand-flushing car owner will comprise that three cylinder pump, sand-flushing liquid processing device all place on the known automobile chassis (1).The sand-flushing liquid processing device is made up of two basket filters in parallel (6), two hydrocyclones in parallel (5), swash plate oil expeller (4) processing unit and filtered water tank (2), former fuel tank (11), sand reservoir box (7), centrifugal pump (10), and each processing unit links to each other by manifold.
Novel oilfield oil well sand washing well-flushing car comprises that mainly three cylinder pump (3) and sand-flushing liquid processing device all place on the known automobile chassis (1).The flushing fluid treating apparatus is made up of two basket filters in parallel (6), two hydrocyclones in parallel (5), swash plate oil expeller (4) processing unit and filtered water tank (2), former fuel tank (11), sand reservoir box (7).
Former fuel tank (11) and filtered water tank (2) are the square chest type structure of one, are divided into two zones by dividing plate.
Be provided with a pipeline in former fuel tank (11) bottom and link to each other with centrifugal pump (10), the crude oil in the former fuel tank pumps in the petroleum pipeline of well site by centrifugal pump (10).
During use, the course of work of oilfield sand-flushing car is: with the power source of chassis (1) motor as three cylinder pump (3), by transmission system chassis (1) engine power is reached three cylinder pump (3), three cylinder pump (3) carries out sand washing with the interior clear water pressurization of filtered water tank (2) after sand clean out pipe injects in the oil well casing, the down-hole sand-laden fluid returns out through oil pipe, the sand-laden fluid that returns out enters two basket filters in parallel (6), oarse-grained silt particle is removed, enter hydrocyclone (5) subsequently and carry out the desanding processing, sand enters in the sand tank (7), water outlet enters airtight swash plate oil expeller (4) oil removing by pipeline, suspension and sand, crude oil in the swash plate oil expeller (4) can regularly enter in the former fuel tank (11) by the former pipeline of oil extraction, swash plate oil expeller (4) water outlet enters filtered water tank (2), water in the filtered water tank (2) is delivered to oil well casing by three cylinder pump (3) again, promptly forms the operation of circulation sand-flushing.
Crude oil in the former fuel tank (11) can regularly be pumped in the petroleum pipeline of well site by centrifugal pump (10).
During blowdown, three cylinder pump (3) is with the clear water pressurization, and by the pipeline 2 (9) that links to each other with swash plate oil expeller (4), the pipeline (8) that links to each other with sand reservoir box (7) realizes that swash plate oil expeller (4) and sand reservoir box (7) clean dirt eliminating function automatically.
