The lower end of the fishing device is of a thin-walled cylinder, and the upper end thereof is connected with thread; the lower end of the fishing device is provided with a radial opening angle (1) and an axial opening angle (5); the cylinder wall (2) of the fishing device is provided with two inclined lugs (3) integrated with the cylinder wall (2), and the lower part of the connecting thread of the inner hole on the upper end of the fishing device is provided with a limit bulge (4); the lug (3) is trapezoid, the lower bottom edge of the trapezoid shape is connected with the cylinder wall (2), and the other three edges thereof are not connected with the cylinder wall (2); and the upper end of the lug (3) inclines to the axes of the fishing device, and the included angle of the lug (3) and the cylinder wall (2) is A. The utility model has the benefits that the fishing device has reasonable design and simple structure, has the functions of the guiding, positioning, fishing and the like, can realize fast fishing and reduces the non-productive time.
Description
Affiliated technical field
The utility model relates to a kind of oil extraction power tool well fisher that falls, and especially relates to a kind of Electric Submersible Pump Unit fisher.
Background technology
Submersible electric pump has been widely used in the oil extraction production as oil production equipment, but removes in the well operations at submersible electric pump, unit takes place sometimes fall the well accident.When the gap between the external diameter of Electric Submersible Pump Unit and the casing inner diameter that fallen into is bigger, have enough annular spaces, use existing fisher can finish fishing; But for Masaru Ibuka, when the annular space between the external diameter of Electric Submersible Pump Unit and the casing inner diameter that is fallen into was smaller, promptly the effective operation space was little, and monolateral sometimes distance has only 5～6mm, salvaged difficulty and increased, and the fishing time is long.Existing Electric Submersible Pump Unit or other similar products fall into well, and the fishing tool of use is a plurality of component to be formed, and the fisher requisite space is big, can not satisfy small void space fishing needs.
The utility model content
In order to overcome existing Electric Submersible Pump Unit fishing tool is that a plurality of component are formed, and the fisher requisite space is big, can not satisfy the deficiency of small void space fishing needs, and the utility model provides a kind of Electric Submersible Pump Unit fisher.
The technical scheme that its technical problem that solves the utility model adopts is: Electric Submersible Pump Unit fisher lower end is a thin wall cylinder, and there is connecting thread the upper end, and the fisher lower end has and radially imports the angle and axially import the angle; Oblique ear with the barrel one is arranged on the barrel of fisher more than 2, and positive stop lug boss is arranged at the bottom of fisher upper end endoporus connecting thread; Tiltedly ear is that trapezoidal, trapezoidal bottom is connected with barrel, and other three limits do not link to each other with barrel; Tiltedly the ear upper end tilts to the fisher endoporus, and tiltedly the angle of ear and barrel is A, and included angle A is 10～15 °; Tiltedly the quantity of ear is 4～8, and along the barrel circumference uniform distribution; Radially import the angle and be the included angle B between fisher lower surface and the fisher cross section, radially importing angle B is 15～25 °; Axially importing the angle is chamfering C in the barrel of fisher lower end, and axially importing angle C is 3～5 °; The thickness of the barrel of fisher is 5～6mm.
The beneficial effects of the utility model are, and are reasonable in design, simple in structure, have functions such as importing, location, salvaging, when especially annular space is smaller between submersible electric pump and sleeve pipe, can realize quick salvaging, reduce the nonproductive activity duration.
Description of drawings
Fig. 1 is the utility model Electric Submersible Pump Unit fisher structural representation.
Among the figure: 1. radially import the angle, 2. barrel, 3. oblique ear, 4. positive stop lug boss 5. axially imports the angle.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model Electric Submersible Pump Unit fisher is a single component, and there is the connecting thread that is connected with fishing string the fisher upper end, and the barrel 2 of fisher lower end is a thin wall cylinder, and the thickness of thin wall cylinder is 5～6mm; The fisher lower end has and radially imports angle 1 and axially import angle 5; Oblique ear 3 with barrel 2 one is arranged on the barrel 2 of fisher, and positive stop lug boss 4 is arranged at the bottom of fisher upper end endoporus connecting thread.
The oblique ear 3 of Electric Submersible Pump Unit fisher is trapezoidal, and the bottom of trapezoidal oblique ear 3 is connected with barrel 2, and other three limits do not link to each other with barrel 2; The following length of side of trapezoidal oblique ear 3 is approximately 2: 1 with the ratio of the last length of side, and trapezoidal oblique ear 3 bottoms are approximately 1: 2 with the ratio of trapezoidal height.Tiltedly ear 3 upper ends tilt to the fisher axis, and tiltedly ear 3 is A with the angle of barrel 2, favourable and fishing when included angle A is 10～15 °; Tiltedly the quantity of ear 3 is generally 4～8, and along barrel 2 circumference uniform distributions; Structure was more reasonable when tiltedly the quantity of ear 3 was 6, and part can be better.
The angle 1 that radially imports of Electric Submersible Pump Unit fisher is the included angle B between fisher lower surface and the fisher cross section, and radially importing angle 1 usually is 15～25 °.The axial importing angle 5 of fisher is chamfering C in the barrel of fisher lower end, and axially importing angle 5 usually is 3～5 °.
The implementation process of the utility model Electric Submersible Pump Unit fisher is, according to the structure of being salvaged submersible electric pump, size with in the degree of depth of down-hole, determine that positive stop lug boss 4 is apart from the size of lower surface in the Electric Submersible Pump Unit fisher, and the number of degrees of the included angle A of oblique ear 3 and barrel 2, the round internal diameter that the upper end of several oblique ears 3 is formed is slightly less than the Electric Submersible Pump Unit outside dimension; Again the Electric Submersible Pump Unit fisher is connected to the lower end of fishing string, with the fishing string G.I.H; When fisher arrives the Electric Submersible Pump Unit position, radially import angle 1 and axially import angle 5 because the fisher bottom has, make submersible electric pump can be imported smoothly in the thin wall cylinder of fisher; When oblique ear 3 arrived the slightly little fishing neck of sizes, tiltedly opened the upper end of ear 3, is stuck in the place, boss rank of being salvaged thing; Upper lifting pipe post then proposes pit shaft until the submersible electric pump of the well that will fall.
The utility model Electric Submersible Pump Unit fisher is not only applicable to fall into the salvaging of the Electric Submersible Pump Unit of pit shaft, equally is applicable to other similar instruments that falls into well of salvaging of needing yet, and particularly can satisfy the smaller fishing needs of annular space.
