Abstract
The invention relates to an oil field horizontal well tool, in particular to a horizontal well sand bailing device. The technical scheme is that the horizontal well sand bailing device is mainly composed of a circulating short section, a sand bailing pump, a sand blocking short section, a sand settling pipe, a centralizer and a horizontal sand shovel. The upper portion of the sand bailing pump is in thread connection with the circulating short section, the lower end of the sand bailing pump is sequentially connected with the sand blocking short section and the sand settling pipe, the horizontal sand shovel is fixed at the end of the and settling pipe, and the centralizer is arranged on the sand settling pipe on a horizontal section. The horizontal well sand bailing device has the advantages of being long in service life due to the fact that friction between the sand bailing pump, a casing and a joint is reduced, and improving operation efficiency due to the fact that the horizontal sand shovel works normally.
Description
Technical field
The present invention relates to a kind of oilfield horizontal well instrument, particularly a kind of horizontal well sand-bailing equipment.
Background technology
In the field produces, owing to long-term exploitation, formation pressure reduce a lot, pressure coefficient eases down to also lower than the equivalent pressure coefficient of water.Use the water flushing sand washing in this case, fluid flow and flow velocity that water entering low pressure layer returns on making in the pit shaft reduce.Coarse sand particles can not effectively be taken ground to.The water that injects when serious can all get into oil reservoirs and can not on return; Cause the sand washing failure, cause the contaminated oil well output of oil reservoir to reduce; Existing sand-bailing equipment sand sediment pipe horizontal segment is when operation; Cause the sand sediment pipe sideslip easily, aggravated the pump housing of sand bucket and the friction between sleeve pipe and the box cupling, make horizontal sand shovel cisco unity malfunction.
Summary of the invention
The object of the invention is exactly the above-mentioned defective that exists to prior art, and a kind of horizontal well sand-bailing equipment is provided.
Its technical scheme is: mainly be made up of circulating sub, sand bucket, sand block pipe nipple, sand sediment pipe, centralizer, horizontal sand shovel; The top of sand bucket is through the circulating sub that is threaded; The lower end of sand bucket connects sand block pipe nipple, sand sediment pipe successively; Described sand sediment pipe end fixed level sand shovel is provided with centralizer on the horizontal segment sand sediment pipe.
Above-mentioned circulating sub is provided with fluid hole.
Above-mentioned horizontal sand shovel end is a pyramidal structure.
The invention has the beneficial effects as follows: the friction between sand bucket and sleeve pipe and the box cupling is few, long service life, and horizontal sand shovel operate as normal has improved operating efficiency.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Among the last figure: oil pipe 1, circulating sub 2, sand bucket 3, sand block pipe nipple 4, sand sediment pipe 5, centralizer 6, horizontal sand shovel 7.
The specific embodiment:
In conjunction with accompanying drawing 1, the present invention is done further description:
The present invention mainly is made up of circulating sub 2, sand bucket 3, sand block pipe nipple 4, sand sediment pipe 5, centralizer 6, horizontal sand shovel 7; The top of sand bucket 3 is through the circulating sub 2 that is threaded; The lower end of sand bucket 2 connects sand block pipe nipple 4, sand sediment pipe 5 successively; Described sand sediment pipe 5 end fixed level sand shovels 7 are provided with centralizer 6 on horizontal segment sand sediment pipe 5; Circulating sub 2 is provided with fluid hole, and it is pyramidal structure that described horizontal sand shovels 7 ends.
During use, transfer sand-bailing equipment in the oil pipe 1, horizontal sand shovel 7 sand setting in the cannula cleaning of starting working; Sand setting is along with sand sediment pipe moves upward; Follow the ring pipe nipple and get rid of, centralizer can effectively prevent the friction of sand-bailing equipment to sleeve pipe, guarantees to drag for normally carrying out of sand work.
