Abstract
The utility model relates to a reducing sleeve oil obtaining apparatus, composed of a union joint, an oil obtaining cylinder, a valve ball, a valve seat, a rubber sealing ring and a piece joint. Screw threads which are arranged at the upper and the lower ends of the oil obtaining cylinder are respectively connected with the union joint and a tail joint; an oil flow channel is arranged on the union joint, the internal diameter of the tail joint is the same as the internal diameter of the oil obtaining cylinder; an annular groove is arranged on the inner side of a cylinder wall at the bottom of the oil obtaining cylinder, and the valve seat which is positioned in the groove is as high as the groove; the valve seat can be fixed by tightening the screw threads of the oil obtaining cylinder and the tail joint, and the rubber sealing ring is sheathed outside the oil obtaining cylinder. Oil can be obtained hermetically with high efficiency in the reducing sleeves of the same one well. The utility model has the advantages of investment saving and convenient oil obtaining.
Description
The utility model relates to a kind of reducing bushing oil obtaining appts.
At present, the oil field uses the pumping car to carry out Batch Process in order to excavate the potentiality of stripper well, though can save a whole set of oil pumping production equipment of well head, can not pumping in sleeve pipe, oil pipe down in the well has increased the oil pipe investment, and has required pipe aperture unanimity, smooth.In addition, because of the bad processing of the oil-field brine of in high water-cut well, extracting out, so also be not suitable for high water-cut well.
The purpose of this utility model is to provide a kind of reducing bushing oil obtaining appts at above-mentioned the deficiencies in the prior art part, can be used in the deep-well more than 2000 meters, is lowered to the sleeve pipe of different inner diameters, all can accomplish the airtight oil production of dragging for, and can save investment, and it is convenient to drag for oil.
The purpose of this utility model is achieved through the following technical solutions: this reducing bushing oil obtaining appts, by connector, drag for the oil tube, valve ball, valve seat, rubber seal ring, the tail joint is formed, oil flow channel is arranged on the connector, screw thread is arranged under it and drag for oil tube and be connected, drag for oil tube bottommost barrel inboard one annular groove is arranged, valve seat places in the groove, its height equates with groove height, dragging under the oil tube has screw thread to link to each other with the tail joint, the tail joint is with to drag for oil tube internal diameter identical, to drag for and valve seat can be fixed after oil tube and tail joint screw thread tighten, and have valve ball, rubber seal to be located on the valve seat and drag for outside the oil tube.The reducing bushing oil obtaining appts is lowered to sleeve pipe, and when rubber seal ring was descending, the undergauge that can be squeezed in the little sleeve pipe of internal diameter passed through, when up owing to the liquid gravity effect is expanded, again can be in the big sleeve pipe of internal diameter the airtight oil that drags for, realize the reducing bushing oil salvage operation.When the reducing bushing oil obtaining appts arrived pasta down, valve ball was promptly backed down by pasta, carries on beginning, valve ball is promptly closed, and rubber seal ring is promptly dilated the contact sleeve tube wall by oil column and realizes airtightly, carries in the continuation to well head, promptly the ground oil tank is advanced in the crude oil bailing in the oil well, finish and once drag for oil production.
The utility model compared with prior art has following advantage: this reducing bushing oil obtaining appts, in the sleeve pipe of same well different inner diameters, all can accomplish the airtight oil production of dragging for, and can save investment, and it is convenient to drag for oil.
Accompanying drawing 1 is the structural representation of reducing bushing oil obtaining appts.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail: the reducing bushing oil obtaining appts is by connector 1, drag for oil tube 2, valve ball 3, valve seat 4, rubber seal ring 5, tail joint 6 is formed, oil flow channel 7 is arranged on the connector 1, screw thread is arranged under it and drag for oil tube 2 and be connected, drag for oil tube 2 bottommost barrel inboards one annular groove 9 is arranged, valve seat places in the groove 9, its height is highly equal with groove 9, dragging for the oil tube has screw thread to link to each other with tail joint 62 times, tail joint 6 is with to drag for oil tube 2 internal diameters identical, can valve seat 4 is fixing after will dragging for oil tube 2 and tail joint 6 screw threads and tightening, valve ball 3 is arranged on the valve seat 4, and rubber seal ring 5 is placed in and drags for outside the oil tube 2.Rubber seal ring 5 is the superposition body of round platform, cylinder, round platform, and inside is the semi-hollow structure, has the function that can mechanical compress again can waterpower dilates.The tail joint has oil tube box 8 for 6 times, can add the oil pipe or the weight-adding hammer that connect different length, on the connector 1 screw thread is arranged, and can connect wire rope socket and wire rope.Valve seat wall and dragging between oily barrel by rubber pad 10 sealings.In the time will dragging for oil in well, well head is installed supporting blowout prevention box, and the blowout prevention box connects pit shaft down for threeway under the threeway, and the side picks out oil pipeline oil-feed jar, and the oil of pulling out is that flow path threeway and flow line enter oil tank.Cylinder is wound with wire rope on the dredging vehicle, transfer from carrying overhead traveling crane, by blowout prevention tape threeway flow line oil-feed jar, rope socket links to each other with the connector 1 of reducing bushing oil obtaining appts, promptly constitute and drag for oily series of tools, transfer wire rope, after oil obtaining appts put into oil well casing, install the well head threeway, at this moment transfer oil obtaining appts and arrive the dark 1500m of pasta always, continue to transfer, at this moment rubber seal ring 5 is squeezed and is close to casing wall, the displacement of reservoir oil enters tail joint 6, and pasta backs down valve ball 3, and oil just enters and drags for oil tube 2, because of rubber seal ring 5 is a round platform, cylinder, the superposition body of round platform, inside is the semi-hollow structure, and scalable 5-10mm is so adapt to three grades of sleeve pipes (as homemade sleeve pipe Φ 125.7mm, Φ 123.7mm, Φ 121.7mm, sleeve pipe Φ 124.3mm made in U.S.A, Φ 121.4mm, Φ 118.6mm), following to 2500m, fluid enters and drags for oil tube 2 tops by dragging for oil flow channel 7 on the oil tube 2, leads to oil tank.At this moment carrying your ball 3 on is semi-closure, and when carrying in the continuation, rubber seal ring 5 is subjected to oil column gravity, this power dilates joint ring, when making its sleeve pipe that passes through different inner diameters, is close to casing wall all the time, so just force the crude oil that drags for inside and outside oily 2 up, arrive well head always, finish and once drag for oil production with oil obtaining appts.
