Abstract
The utility model relates to a kind of NEW TYPE OF COMPOSITE fisher, mainly solves the problem of existing oil pipe class falling object fishing tool function singleness.Comprise top connection 1, die nipple 2, urceolus 3, slide block 4, die nipple in the urceolus of top connection and lower end and urceolus top inner chamber is connected, and die nipple outer wall has tapered thread, and the tapering of tapered thread is 1: 16, thread form angle 55 degree, urceolus bottom has two pieces to be axisymmetric slide block with center line, can salvage common downhole oil tubing junk, can also salvage the irregular oil pipe junk of fracture, applied range, handled easily, reliability is high, can effectively improve fishing process.
Description
Art
The utility model relates to a kind of oil field underground operation tool, is a kind of composite latch jack, is specially adapted to fracture irregular oil pipe class fishing junk and uses.
Background technology
In the existing oil pipe class falling object fishing tool of oil field, its fishing tool function is all often more single, be applicable to carrying out corresponding salvaging to the oil pipe junk of given shape, but due to subsurface environment and junk situation complexity, especially fracture irregular oil pipe class junk is not easily salvaged, these power tools have its limitation, and reliability and success rate are all difficult to accomplish the end in view.
Summary of the invention
The utility model, for above-mentioned prior art Problems existing, provides a kind of NEW TYPE OF COMPOSITE fisher.
The technical solution used in the present invention is to achieve these goals: a kind of NEW TYPE OF COMPOSITE fisher, comprise top connection 1, die nipple 2, urceolus 3, slide block 4, to be top connection be connected with the die nipple in the urceolus of lower end and urceolus top inner chamber its design feature, die nipple outer wall has tapered thread, and slide block is arranged at urceolus bottom.
The tapering of the tapered thread on die nipple outer wall is 1: 16, thread form angle 55 degree, and urceolus bottom has two pieces to be axisymmetric slide block with center line.
The beneficial effects of the utility model are: can salvage common downhole oil tubing junk, and can also salvage the irregular oil pipe junk of fracture, applied range, handled easily, reliability is high, can effectively improve fishing process.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure: 1. top connection; 2. die nipple; 3. urceolus; 4. slide block.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises top connection 1, die nipple 2, urceolus 3, slide block 4, top connection upper end is connected with oil pipe, lower end is connected with the die nipple 2 in urceolus 3 and urceolus top inner chamber, and die nipple 2 outer wall has tapered thread, and the tapering of tapered thread is 1: 16, thread form angle 55 degree, be convenient to salvage tube inner wall thread making, the bottom of urceolus 3 has two pieces to be axisymmetric slide block 4 with fisher center line, can apply power salvage oil-pipe external wall.When running into oil pipe junk fracture and being irregular, oil pipe can be introduced between die nipple 2 and urceolus 3, urceolus lower slider 4 drags for oil-pipe external wall, and die nipple 2 pairs of tube inner walls carry out thread making salvaging, thus salvaged, which thereby enhance the salvaging efficiency to oil pipe class junk and reliability.
