Abstract
The utility model relates to a shearing-type high temperature resistant corrosion-resistant oil drainage device for the downhole operation of an oil well, comprising an oil drainage part and a shearing part which are respectively composed of a cylinder body (1), a shearing ring (2), a metal sealing ring (3), a hollow pin nail (4), a compression nut (5), a connecting hoop (6), a sliding slip (7) and a shearing rod (8) and are matched. The oil drainage device has the advantages of novel design, good sealing performance, high oil drainage successful rate, high temperature resistance, corrosion resistance, easy production and repair, low cost and expense, etc.; the utility model can be used for various well operations of thin oil, thick oil, high solidification oil, etc.
Description
The utility model relates to a kind of downhole tool that is used for the oil well operation: shearing corrosion-and high-temp-resistant bleeder.
At present relate to a kind of downhole tool that is used for the oil well operation with novel: shearing corrosion-and high-temp-resistant bleeder has autocontrol, brace type, switching regulator, reverse buckling type etc. multiple, but the poor-performing of these bleeders, only be applicable to the operating mode of thin oil normal temperature, and its draining success rate and not really high, phenomenons such as that the sealing position is often stung is bad, leakage.Especially when viscous crude or high-solidifiability oil well use,, add that its operation part often breaks down because its hermetic unit can not high temperature resistant and corrosion, the draining success rate is lower, repeats operation, both wasting manpower and material resources when often causing well construction, influence oil well output again, reduce economic benefit.
Task of the present utility model is to provide a kind of shearing corrosion-and high-temp-resistant bleeder, the sealing of this kind bleeder is reliable, be not only applicable to thin oil normal temperature and have higher draining success rate, guarantee carrying out smoothly of oil well underground work at viscous crude or high coagulating under oil, high temperature and the etching condition.
The utility model is to realize like this.It comprises oil bleeding part and cutting out section, form by cylindrical shell (1), shearing ring (2), metallic packing ring (3), hollow pin (4), clamping nut (5) and box cupling (6), slip slips (7), shear rod (8) respectively, two parts are used, and its structure and assembling feature are as follows:
Shearing ring (2) is equipped with at the middle part in the cylindrical shell (1), hollow pin (4) is housed respectively in the eyelet of both sides, and clamping nut (5) is equipped with in its outside, and nut (5) is connected with cylindrical shell (1) by screw thread, be set with metallic packing ring (3) on the hollow pin (4), above-mentioned parts constitute oil bleeding part; Box cupling (6) links to each other with shear rod (8) upper end by screw thread, is set with slip slips (7) on the shear rod (8), and above-mentioned parts constitute cutting out section.During use, the oil bleeding part of this bleeder is connected on the 3rd oil pipe more than the deep well pump, together down to projected depth, at this moment, oil bleeding part is in sealing state with tubing string.The cutting out section of this bleeder is connected on first sucker rod in deep well pump plunger top, goes into the well with plunger.When the cutting out section of bleeder passes through oil bleeding part,, pass through oil bleeding part smoothly because the effect of slip slips (7) the bottom conical surface is shunk its external diameter.After plunger enters the deep well pump pump barrel, promptly begin normal oil pumping.When oil well needs operation, on carry rod string, after reaching certain distance, cutting out section contacts with oil bleeding part on being connected tubing string.Because the effect that shear rod (3) is upper conical makes slip slips (7) spreading, blocks below shearing ring (2).Carry sucker rod in the continuation, shearing force just is applied on the hollow pin (4), and after shearing force surpassed the shear strength of hollow pin, pin was cut off, and the oil stream in the tubing string promptly releases from the hole of oil bleeding part cylindrical shell (1), so that oil well underground work is carried out smoothly.
The utility model modern design, rational in infrastructure, good seal performance, draining success rate height, and can be high temperature resistant, corrosion-resistant can be at thin oil, viscous crude, highly use when coagulating the various oil well operation of wet goods.This bleeder is easy to make, repairs, and manufacturing, rehabilitation expense are lower, are suitable for and apply.
Fig. 1 is the utility model oil bleeding part structural representation.
Fig. 2 is the utility model cutting out section structural representation.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
In the utility model, cylindrical shell (1) structure is similar to tubing coupling, its upper and lower end is shaped on the yin, yang screw thread that links to each other with oil pipe respectively, the both sides, middle part are respectively equipped with the circular hole of supplying apparatus shearing ring (2), metallic packing ring (3), hollow pin (4) and clamping nut (5), be provided with shoulder and screw thread in the circular hole, cylindrical shell middle part inner headed face is established a shoulder of putting shearing ring (2).Shearing ring (2) is a cylindrical member, and its both sides, middle part have the circular hole that is used to install hollow pin (4).Hollow pin (4) is a book wall hollow object, the sealing of one end, and the other end is uncovered.Clamping nut (5) cylindrical is worn pin thread, and inner surface is made hexagon, so that it is screwed into cylindrical shell (1) screw or lays down.Slip slips (7) but be that a usefulness elastic metallic material is made the radially cylinder of harmomegathus, be uniformly distributed with the vertical groove in 4 roads along the circumference, its lower end periphery bloats, this bloat the periphery upper and lower part in addition for just, the rounding conical surface, there is a step that is used for shearing ring is applied axial force on the face of cylinder, middle part.Shear rod (8) is that two ends are shaped on respectively and box cupling (6) and the bottom rod collar rod member of the pin thread of logotype mutually about in the of one, and there is a taper surface its underpart, is used for guaranteeing to apply reliably shearing force at the last sliding merit slips (7) of spreading when carrying draining.
