Description
Technical field
The utility model relates to a kind of horizontal well sand washing fishing integrated tool, belongs to oil extraction in oil field well workover technology field.
Background technology
In oilfield downhole operation construction, because the reasons such as small falling object that produce in formation sand production and underground work process cause, when later stage operation, need sand washing and fishing.Current many employing blank tubings carry out sand washing operation and fishing cup fishing two-step hockets, when sand washing operation path cannot be carried out by small article obstruction, use fishing cup fishing instead, after salvaging, carry out again blank tubing sand washing operation, long construction period, simultaneously, fishing cup fishing weak effect in horizontal well, the hinge dipper using in straight well cannot play a role in horizontal well, complex procedures, and operating cost is high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of horizontal well sand washing fishing integrated tool.
A fishing integrated tool, top connection and cylindrical shell are casing section mill pipe, one end screw thread of top connection and cylindrical shell is 2
7/
8" UPTBG, top connection and cylindrical shell lower end are the oblique point of 30 °, top connection and cylindrical shell and go into the well 2
7/
8" UPTBG oil pipe is connected; 2 of Φ 4mm holes are arranged at top connection and cylindrical shell bottom, and hole connects bearing pin, and bearing pin is connected with hinge, spring, top connection and cylindrical shell and bearing pin welding; Keeping hinge vertically and the position of top connection and cylindrical shell, welded limiting piece is on the inwall of top connection and cylindrical shell.
The utility model has the advantages that to meet and in diameter, inclined shaft, horizontal well, carry out sand washing, salvaging small falling object integrated function; Simple in structure, cost is low, and sand washing is salvaged simple to operate; Solved sand washing, small falling object is salvaged the problem that operation is various, duty cycle is long, operating cost is high; Solved horizontal well small falling object and salvaged the large problem of difficulty, avoided using other fishing tools, the small falling object of salvaging is limited in scope, thoroughly the disposable problem of all pulling small falling object out; On this hinge dipper hinge, turn over rear passage large, there is salvaging scope large, be not subject to the advantage of tubing diameter restriction.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is generalized section of the present utility model.
Fig. 2 is the schematic cross-section of Fig. 1.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2,
A fishing integrated tool, is comprised of top connection and cylindrical shell 1, bearing pin 2 and spring 3, hinge 4 and limited block 5, and top connection and cylindrical shell 1 are casing section mill pipe, and one end screw thread of top connection and cylindrical shell 1 is 2
7/
8" UPTBG, top connection and cylindrical shell 1 lower end are the oblique point of 30 °, top connection and cylindrical shell 1 with go into the well 2
7/
8" UPTBG oil pipe is connected; 2 of Φ 4mm holes are arranged at top connection and cylindrical shell 1 bottom, and hole connects bearing pin 2, and bearing pin 2 is connected with hinge 4, spring 3, top connection and cylindrical shell 1 and bearing pin 2 welding;
Keeping hinge 4 vertically and the position of top connection and cylindrical shell 1, welded limiting piece 5 is on the inwall of top connection and cylindrical shell 1.
The lower end of top connection and cylindrical shell 1 is the nib of 30 °, plays guide shoe effect in the process of going into the well, and is convenient to sand washing operation.
Hinge 4 has reset function under the effect of spring 3, and assurance hinge 4 is being close to limited block 5 without fluid as the used time; The diameter of hinge 4 matches with the internal diameter of cylindrical shell 1.
The use procedure of summary horizontal well sand washing fishing integrated tool.Consult Fig. 1.In workover treatment process, at needs, carry out sand washing, there is small falling object Sha Mian position simultaneously, in the time of cannot realizing sand washing operation, can adopt horizontal well sand washing fishing integrated tool, carries out sand washing and salvages one-trip string operation.Concrete operation process is: at horizontal well sand washing fishing integrated tool down to sand face or the above 1-2 rice of small falling object, the anti-high flow rate washover that circulates of turn on pump, under the effect of fluid, hinge is opened, oil jacket circulation is unimpeded, transfer tubing string, transfer on circulation limit, limit, it is inner that small falling object enters hinge dipper, diameter is less, the sand grains of following that quality is light is circulated to ground, diameter is larger, quality is heavy, and to be suspended in hinge dipper inner, when sand washing is to target location, fully circulation well cleanup is consistent to importing and exporting water quality, termination of pumping, hinge resets under the effect of spring, close dipper inner chamber, small falling object is salvaged to dipper inner chamber, with mentioning ground on fishing string.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
