Abstract
The utility model is related to a kind of device for oil exploitation, more particularly to a kind of oil pipes box cupling of releasable stress.Oil pipes box cupling, including box cupling body, box cupling body internal thread segment are provided with flat segments.Flat segments are set at the utility model oil pipes and box cupling body screw thread, stress when oil pipes and the fastening of box cupling inside is released, box cupling and oil pipes service life is extended.
Description
Technical field
The utility model is related to a kind of assembling pipe joint, specifically provides a kind of oil pipes of releasable stress and connects
Hoop.
Background technology
Petroleum pipe coupling is mainly used in the connection of oil pipe, when drilling well get into target zone (oil-containing, gas layer position), oil reservoir need to be used
Sleeve pipe all seals the exposed stratum of oil-gas Layer and top, is oil reservoir inside production string.Under production string is in all kinds of sleeve pipes
Well depth is most deep, and its mechanical property and sealing property requirement are also highest, and in production operation, oil pipes box cupling is continuous
Fastening causes local pressure excessively to concentrate, and causes box cupling thread failure occur, easily causes oil pipe and comes off and causes danger.
Utility model content
The purpose of this utility model is in order to solve stress when box cupling and petroleum pipeline are fastened during oil pipes box cupling operation
Concentrate, spy provides a kind of oil pipes box cupling of releasable stress.
It is that, up to this purpose, the utility model uses following technical scheme：
The utility model includes oil pipes and box cupling body, wherein in oil pipes and box cupling body between screw thread
Flat segments are set.
Specifically, flat segments distance is 2-3cm.
Specifically, the oil pipes being connected with box cupling（2）It is also provided with flat segments.
Flat segments are set at the utility model oil pipes and box cupling body screw thread, oil pipes and box cupling is released
The stress during fastening of inside, extends box cupling and oil pipes service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1 box cupling body, 2 oil pipes, 3 flat segments.
Specific embodiment
The utility model includes oil pipes 2 and box cupling body 1, and oil pipes 2 and the inside of box cupling body 1 set flat
Straight section 3, weakens stress concentration during fastening, extends oil pipes and box cupling service life, improves service efficiency.
Finally it should be noted that:Above example is only used to illustrate the technical solution of the utility model rather than it is limited
System；Although being described in detail to the utility model with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without deviating from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
In the middle of scope.
Claims (3)
1. a kind of oil pipes box cupling of releasable stress, including box cupling body（1）, it is characterised in that：In the box cupling sheet
