Description
Technical field
The utility model relates to tools for downhole of oil field fields, and in particular to a kind of oil gas downhole tool rope socket group
Part.
Background technique
Mainly hung at present into oil/gas well using wire rope socket when tripping in tool will tripping in tool string, in rope socket
A knot is beaten in inner cavity lower part, by its G.I.H after rope socket lower suspension tool string.But into well when lower tool pair
Tubing string clean-up performance is more demanding in oil/gas well, since the pull-off force for the test steel wire gone into the well is smaller, occurs to meet card etc. in well
It cannot adopt an effective measure in time when situation and avoid accident, be only capable of by bullet steel wire or other means unfreezing.
A kind of novel well testing unfreezing rope socket is disclosed in the utility model patent that Authorization Notice No. is CN204200139U,
Including rope socket ontology, the inner hollow of rope socket ontology, bottom end is equipped with internal screw thread one, and upper end is equipped with rope bottleneck, in rope bottleneck
Across rope, rope end is connected with setting in the intrinsic weight of rope socket, and the top of internal screw thread one is equipped with internal diameter and is less than interior spiral shell
The external screw thread of the internal screw thread two of line one, internal screw thread two and weight bottom cooperates, and weight bottom is stupefied convex equipped with screwing up.In the process of going into the well
When middle chance is blocked, weight is displaced downwardly to rope socket bottom under the action of self gravity and steel wire, and steel wire is mentioned on hand winch, and weight moves up
Rope socket inner cavity top is collided, instantaneously applies a upward impact force to rope socket, then slowly transfers again, above mention steel wire, it is anti-in this way
Multiple operation carries out multiple impacts, concussion, is finally reached the purpose of unfreezing.
Above-mentioned unfreezing rope socket hits unfreezing using the continuous put-on and delegated weight of steel wire, needs frequent reciprocating operation, time-consuming to take
Power, if especially tool string card resistance is in the inclination section of oil/gas well, put-on and delegated steel wire is inconvenient repeatedly, and the works such as steel wire clipper
Tool cannot effectively cut the steel wire at rope socket head again, not be available the fishing tools such as bumper jar, fishing socket, and it is difficult to increase salvaging
Degree.
Utility model content
The purpose of this utility model is to provide a kind of oil gas downhole tool rope socket components, to solve to survey in the prior art
Test instrument, which is gone into the well, meets unfreezing inconvenience, technical problem poor for applicability when blocking.
To achieve the above object, a kind of technical solution that the utility model oil gas downhole tool is used with rope socket component: oil
Gas downhole tool rope socket component, including the rope socket ontology for connecting steel wire ropes, it is opening that the rope socket ontology, which has lower part,
The mounting cylinder section of structure, mounting cylinder section is interior to be connected with the fishing head for connecting tripping in tool, the shackle member by shackle member
It is used to that tearing or deformation to occur when being squeezed by fishing head so that fishing head disengaging is restricted on barrel for mounting cylinder section is arranged in
Cap ontology, elastomer block or elastic band made of elastic material, circumferentially-spaced distribution of the elastomer block along barrel, elasticity
Circumferentially extending of the ring along barrel.Wherein tripping in tool can be logging tool or well testing tool etc., but be not intended to salvaging
Fishing tool.
The beneficial effects of the utility model are: the rope socket component of the utility model passes through the shackle member that is located in mounting cylinder section
Fishing head is connected in mounting cylinder section by radial be engaged by clamping with fishing head along mounting cylinder section, because shackle member can be when being squeezed
Tearing occurs or deforms so that fishing head disengaging, directly can above be mentioned rope socket ontology by above mentioning steel wire when tool goes into the well chance card
Well out, and the fishing head by connecting above tripping in tool carries out secondary salvaging, structure is simple, easy to operate, unfreezing success rate
Height, and it is applied widely.
Further, the shackle member is the elastic band, and the barrel of the mounting cylinder section is equipped with to be prolonged along its circumferential direction
That stretches is used to install the annular groove of elastic band.It is easy for installation using elastic band, and guarantee that fishing head and mounting cylinder section exist
It is fixed during going into the well.
The shackle member is disposed with multistage along the axially spaced-apart of mounting cylinder section.It can adjust according to actual needs in mounting cylinder section
The number of shackle member makes fishing head also guarantee to can be easily separated when meeting card while being connected firmly with mounting cylinder section.
Moreover, the upper end of the fishing head is equipped with pyramidal structure, be equipped with below pyramidal structure on fishing head for phase
Answer the recess portion of shackle member snap fit.Facilitated using pyramidal structure and head into fishing head in mounting cylinder section by squeezing elastic component,
And it is salvaged convenient for the later period.
Preferably, the shackle member is rubber block or rubber ring.Using rubber parts be squeezed elastic deformation occurs after can
It is basic to restore to the original state, convenient for recycling.
Further, it is equipped in the top of the fishing head for providing lower pressure to shackle member in the mounting cylinder section
Pressure spring, the pressure spring have the upper end pressed with rope socket ontology and press with fishing head to provide the lower end of lower pressure.It avoids being clamped
Part is during going into the well because concussion falls off.
The rope socket ontology is equipped with the fixation spacer ring for pressing pressure spring upper end.Pressure spring and steel are separated using fixed spacer ring
Cord cap section, avoids wire rope socket section from entering in pressure spring.
Activity is equipped with movable yoke frame between the pressure spring and fishing head, the upside and pressure spring lower end of the activity yoke frame
The upper end pushing tow of press, downside and fishing head cooperates.Preventing fishing head to be stuck in pressure spring cannot normally be detached from rope socket ontology.
The mounting cylinder section is equipped with the stopping surface block step directed downwardly for preventing the movable yoke frame uplink.
The mounting cylinder section is equipped with the disconnecting prevention structure for preventing lifting rope cap ontology rear compression spring from falling off to extend internally.
