Description
Technical field
The utility model relates to special tool under the oil well, relates in particular to a kind of down-hole steel wire operation instrument.
Background technology
In oilfield development process, according to oilfield well testing and oil well adjustment, transformation, perfect, the needs of taping the latent power, according to production engineering specifications, utilize cover ground and underground equipment, instrument, oil, gas, well are taked various down-holes technical measures, reach the amount of adopting of improve annotating, improve oil-gas Layer seepage flow condition and oil, gas, well technology status, rationally control oil recovery, gas producting rate and finally improve the purpose of recovery ratio.This a series of down-holes construction technology technology is referred to as underground work.
Major part all was to adopt the oil pipe operation in the past, and its shortcoming is: operating difficulties, working strength is big, is unfavorable for environmental protection.The applicant wishes to design a kind of steel wire operation instrument, by steel wire, finishes underground work, goes into the well being easy to.
The utility model content
At the problems referred to above, the utility model provides a kind of down-hole steel wire operation instrument, to solve oil pipe Job Operations difficulty in the prior art, the problem that working strength is big.
To achieve these goals, the technical solution of the utility model is as follows:
Down-hole steel wire operation instrument, it is characterized in that, comprise that a front end is used for the rope socket that is connected with steel wire, the rear end of described rope socket is threaded and one is used for the minimized steel wire swivel of steel wire moment of torsion, described steel wire swivel comprises the main part of front end and the Connection Block of rear end, be rotatably connected between described main part and the Connection Block, the afterbody of described Connection Block is threaded with a weighted lever, the rear end of the described weighted lever bumper jar that is threaded, the rear end of the described bumper jar universal ball joint that is threaded, described universal ball joint is divided into leading portion and back segment two parts, the rear end face of described leading portion part is provided with ball recess, the front end of described back segment part is provided with the globe joint that is complementary with described ball recess, and the rear end of described universal ball joint is connected with corresponding tool by snap joint.
The utlity model has simple in structurely, cost is low, in light weight, convenience operation.
The utility model has been realized the down-hole steel wire operation by being connected with steel wire.It is applied widely, and is easy to go into the well.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, down-hole steel wire operation instrument comprises rope socket 1, rope socket inside is provided with awl core 11, is used for being connected with steel wire and blocking steel wire, and the rear end of rope socket is provided with screw 12, be used for being threaded with steel wire swivel 2, the purpose that the steel wire swivel is set is the steel wire moment of torsion is minimized.The steel wire swivel comprises the main part 21 of front end and the Connection Block 22 of rear end, is rotatably connected between main part 21 and the Connection Block 22.
The afterbody of Connection Block has screw, and weighted lever 3 is threaded with steel wire swivel 2 by this screw, and it is in order to guarantee that integral body has enough weight, overcomes entrance friction and goes into the well smoothly that weighted lever is set.
The rear end of weighted lever 3 bumper jar 4 that is threaded makes the solid tool string obtain very big strength by jarring, thereby finishes steel wire operation; Perhaps when the solid tool string be lowered to, on carry in the process and being stuck, realize passing through with lighter jarring.
The rear end of bumper jar 4 universal ball joint 5 that is threaded, universal ball joint 5 is divided into leading portion and back segment two parts, and the rear end face of leading portion part 51 is provided with ball recess 53, and the front end of back segment part 52 is provided with the globe joint 54 that is complementary with ball recess 53.By the angular deflection between these universal ball joint 5 realization bumper jars 4 and the pulling and running tool 7, it is consistent with the oil pipe incline direction to be beneficial to regulate the solid tool string, when particularly carrying out steel wire operation in crooked oil pipe and in the directional well, this universal ball joint can guarantee normally carrying out of steel wire operation.
The rear end of universal ball joint 5 is connected (realization corresponding action) by snap joint 6 (so that quick connection of pulling and running tool) with corresponding tool.Among Fig. 1 in the present embodiment, this corresponding tool is a pulling and running tool 7, and pulling and running tool 7 is used to throw in and salvage the instrument of outer fishing neck.When fishing tool is failed, can jarring slip out of the hand.
After earlier the utility model being connected, steel wire is pressed in the rope socket, taut wire can carry out steel wire operation.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the manual is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
