Abstract
The utility model relates to the technical field of lifting subs, and provides a lifting sub capable of entering a well. The lifting sub capable of entering the well comprises a body, wherein a through hole which is communicated from top to bottom is arranged in the body, the upper end of the body is provided with conical inner threads, the lower end of the body is provided with conical outer threads, an annular groove is arranged in the middle of the outside of the body, the upper end of the groove is in a wide-end-up conical shape, an included angle between an upper end face of the groove and a vertical face of the groove is 18 degrees, the lower end of the groove is in a wide-end-down conical shape, and an included angle between a lower end face of the groove and the vertical face of the groove is 18 degrees. The lifting sub capable of entering the well is reasonable and compact in structure and convenient to use. Due to the fact that the upper end of the body is in thread connection with a lifting appliance, the body and a tubular column can be lifted together, and the lifting sub capable of entering the well does not need to be disassembled, and therefore labor intensity caused by disassembling the lifting sub is reduced, operating time is reduced, work efficiency is improved, and potential safety hazards are reduced.
Description
Technical field
the utility model relates to the lifting sub technical field, is a kind of well formula lifting sub of going into.
Background technology
because the lifting sub top of using can't be connected with the lifting suspender in the past, need to remove lifting sub when on to down-hole string, carrying, and cause whole process operation complicated, and labour intensity is big, and the operating time is long, and efficient is low; Simultaneously because because of the long-time lifting sub of removing is positioned at well head, there is certain potential safety hazard in the staff.
Summary of the invention
the utility model provides a kind of well formula lifting sub of going into, and has overcome the deficiency of above-mentioned prior art, and it can effectively solve the lifting sub that in the past used, complicated operation, and labour intensity is big, and the operating time is long, inefficient problem.
The technical scheme of
the utility model realizes through following measure: a kind ofly go into well formula lifting sub, comprise body; The through hole that communicates is up and down arranged in body, conical internal thread is arranged in the upper end of body.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
Can there be conical external screw thread the lower end of
above-mentioned body.
The outer middle side part of
above-mentioned body can have the groove of annular.
The upper end of
above-mentioned groove can be taper wide at the top and narrow at the bottom, and the upper surface of groove and the angle of vertical plane are 18 °; The lower end of groove is up-narrow and down-wide taper, and the lower surface of groove and the angle of vertical plane are 18 °.
Can there be marking groove in the outside, bottom of
above-mentioned body.
the utility model reasonable and compact in structure, easy to use; Be threaded with promoting suspender through the body upper end, body can be promoted with tubing string, need not dismantle; Reduce the labour intensity that brings because of the dismounting lifting sub, reduced the operating time, improved operating efficiency, reduced potential safety hazard.
Description of drawings
accompanying drawing 1 is the main TV structure sketch map of the utility model most preferred embodiment.
Coding in
accompanying drawing is respectively: 1 is body, and 2 is through hole, and 3 is groove, and 4 is marking groove.
The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description 1, as: the position relation of upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
shown in accompanying drawing 1, this can be gone into well formula lifting sub and comprise body 1; The through hole 2 that communicates is up and down arranged in body 1, conical internal thread is arranged in the upper end of body 1.
Can according to actual needs above-mentioned A be done further to optimize or/and improve:
shown in accompanying drawing 1, have conical external screw thread in the lower end of body 1.Being convenient to body 1 is connected with tubing string.
have the groove 3 of annular at the outer middle side part of body 1 shown in accompanying drawing 1.Can reduce the weight of body 1 like this, it is lighter that body 1 is used.
shown in accompanying drawing 1, the upper end of groove 3 is taper wide at the top and narrow at the bottom, and the upper surface of groove 3 and the angle of vertical plane are 18 °; The lower end of groove 3 is up-narrow and down-wide taper, and the lower surface of groove 3 and the angle of vertical plane are 18 °.Can prevent that like this stress occurring at the upper surface of groove 3 and place, lower surface concentrates, and the situation of fracture takes place.
have marking groove 4 in the outside, bottom of body 1 shown in accompanying drawing 1.In marking groove 4, be carved with the marking of title and model.
above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
