Abstract
The utility model relates to a bailing device, in particular to a double-barreled circular bailing device. The technical scheme provided by the utility model is that the double-barreled circular bailing device is mainly formed by a bailing pipe, a bailing cone point and a scour pipe, wherein the bottom part of the bailing pipe is provided with the bailing cone point, the bailing pipe is internally provided with the scour pipe, and the upper part of the bailing pipe is provided with multiple liquid draining holes. The double-barreled circular bailing device disclosed by the utility model has the beneficial effects that by arranging the liquid draining pipe in the bailing pipe, the washing of deposited sand at the bottom part can be realized, the sand washing can be realized, the oil well production can be increased, and the labor intensity of a worker can be reduced.
Description
Technical field
The utility model relates to a kind of sand-bailing equipment, and sand is dragged in particularly a kind of two-tube circulation.
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.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of two-tube circulation to drag for sand, realizes sand washing, improves oil well output, reduces labor strength.
Its technical scheme is: mainly by drag for sandpipe, drag for the abrasive cone point, sand clean out pipe is formed, and drags for the sandpipe bottom and is provided with and drags for the abrasive cone point, described dragging for is provided with sand clean out pipe in the sandpipe, the described sandpipe top of dragging for is provided with a plurality of outages.
The beneficial effect of the utility model is: be provided with towards the liquid pipe through being employed in to drag in the sandpipe, can realize that the bottom sand setting is rinsed out, realize sand washing, improve oil well output, reduce labor strength.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: drag for sandpipe 1, drag for abrasive cone point 2, oil pipe 3, outage 4, sand clean out pipe 5, sand setting 6.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly by drag for sandpipe 1, drag for abrasive cone point 2, sand clean out pipe 5 is formed, drags for sandpipe 1 bottom and is provided with that to drag for abrasive cone sharp 2, described dragging for is provided with sand clean out pipe 5 in the sandpipe 1, described sandpipe 1 top of dragging for is provided with a plurality of outages 4.
During use, transfer in the oil pipe 3 and drag for sandpipe 1, start sand-bailing equipment, drag for abrasive cone point 2 and start working, get into oil pipe bottom sand setting 6, the flushing liquor in the sand clean out pipe 5 drives the bottom sand setting and moves upward, and through the outage that drags on the sandpipe sand setting is taken out of.
Claims (1)
