Abstract
An oil-water well sand pump comprises a fluid valve, a blocking connector, a piston connecting pipe and a pump barrel, wherein a discharge valve is arranged on the fluid valve, and consists of a shunt connector, a valve bank and an outer pipe; the valve bank is coupled with the small thread of the lower part of the shunt connector; the upper part of the outer pipe is coupled with the big thread of the lower part of the shunt connector; the lower part of the outer pipe is coupled with the upper part of the fluid valve, and the lower part of the fluid valve is coupled with the upper part of the piston connecting pipe; the piston connecting pipe is provided with a key block, and is arranged in the pump barrel; the upper part of the pump barrel is provided with the blocking connector which is provided with a key groove, and the key block is arranged in the key groove; the shunt connector is provided with an outlet passage and a vertical passage; the pump barrel can be driven to rotate by the key block; when the impurities exist in the well, the oil pipe is rotated to drill the impurities to eliminate the effect of the impurities on the sand fishing; and since the discharge valve is designed, when sand can not be fished, the fluid flow sand washing method is adopted to remove the cumulated sand on the bottom of the well to avoid the ineffectual sand fishing. Thereby, the utility model has efficient sand removal rate.
Description
One, technical field
The utility model is the downhole tool that the oil-water well workover treatment is used, particularly a kind of oil-water well sand bucket.
Two, background technology
Sand in the oil-water well stratum can be carried out by liquid stream, and flowing to liquid of having reaches ground, and the meeting that has deposits in pit shaft, fall into the shaft bottom of oil-water well, after the sand that falls into the oil-water well shaft bottom increased, sand can bury oil-water-layer, the plugging fluid circulation road makes oil-water well be in end-of-life state.In order to recover oil-water well production, the sand that must will fall into the shaft bottom is removed clean.The way of removing the shaft bottom sand at present is to adopt liquid stream sand washing method and pump to take out two kinds of methods.Adopt liquid stream sand washing method load fluid from the oil pipe afterbody sand to be dashed the back and flow in the stratum, sand can not return out ground, and the sand that enters the stratum can flow out formation influence production again in the oil-water well manufacturing process.Adopt the pump method of taking out also to have some problems, present sand bucket can not rotate, and just drags for when in the well foreign material being arranged and does not shake out.
Three, summary of the invention
The purpose of this utility model is a kind of oil-water well sand bucket of design, and it can be rotated, and also can adopt the sand washing of liquid stream.
The purpose of this utility model has been achieved in that liquid valve, the retaining joint, the piston connecting tube, pump barrel, blow off valve is installed on liquid valve, blow off valve is by tap, the valve group, outer tube is formed, the valve group connects with tap bottom minor thread, outer tube top connects with tap bottom major thread, the outer tube bottom connects with liquid valve top, the liquid valve bottom connects with piston connecting tube top, the key piece is arranged in the piston connecting tube, the piston connecting tube is in the pump barrel, and the retaining joint is installed on pump barrel top, on the retaining joint keyway is arranged, the key piece has in the keyway the retaining joint, and passing away and vertical passageway are arranged on the tap.
The beneficial effects of the utility model are: under the effect of key piece, can drive the pump barrel rotation, when in the well foreign material being arranged, can carry out drilling to foreign material by rotation pipeline, eliminate foreign material to dragging for the influence of sand; Owing to designed blow off valve, when sand drags for to come out, can adopt liquid stream sand washing method to remove well and recognize prodelta clay sand, it is unsuccessful to avoid dragging for sand.Therefore, the utility model sand removal success rate height.
Four, description of drawings
Accompanying drawing 1 is the assembling drawing of the utility model embodiment.
Accompanying drawing 2 is the sectional drawings at A-A place in the accompanying drawing 1.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
On liquid valve 6, blow off valve is installed, blow off valve is made up of tap 1, valve group 4, outer tube 5, valve group 4 connects with tap 1 bottom minor thread, outer tube 5 tops connect with tap 1 bottom major thread, outer tube 5 bottoms connect with liquid valve 6 tops, liquid valve 6 bottoms connect with piston connecting tube 9 tops, key piece 7 is arranged in the piston connecting tube 9, piston connecting tube 9 is in the pump barrel 10, retaining joint 8 is installed on pump barrel 10 tops, on the retaining joint 8 keyway is arranged, key piece 7 has in the keyway retaining joint 8, and passing away 2 and vertical passageway 3 are arranged on the tap 1.Piston connecting tube 9 bottoms connect drags for the sand piston, and pump barrel 10 bottoms connect filter sand pump, sand sediment pipe, advance sand valve, nib etc., filter sand pump, sand sediment pipe, advance the sand valve, nib is a prior art, in Figure of description, do not draw.
When dragging for sand, liquid drains in the sleeve pipe from the passing away 2 on valve group 4, the tap 1.
When in the well foreign material being arranged, rotation pipeline under 7 effects of key piece, can drive pump barrel 10 rotations, and foreign material are carried out drilling, eliminates foreign material to dragging for the influence of sand.Can adopt liquid stream sand washing method to remove well when sand drags for to come out and recognize prodelta clay sand, sand cleaning fluid goes out sleeve pipe to be squeezed into, and valve group 4 is closed, and passing away 2 blocks, and sand cleaning fluid returns out under pump, sand has been carried from the vertical passageway 3 of tap 1 flowed to oil pipe, flows out ground again.
