Description

Oil well safety joint
Technical field
The utility model relates to a kind of joint, particularly a kind of oil well safety joint.
Background technology
Safety joint is a kind of security tool be connected in well on tubing string, for drilling well, salvage, well-flushing, in the operation such as well workover and test, in the later development of oil field, sand control is the important measures improving oil well output and stable oil well output, because oil well is more serious containing sand, sand-proof pipe is by sand plug, sand buries, losing sand control effect is recurrent thing, normally produce for making oil well and often well workover must change sand-proof pipe, and once there is fracture or come off in flow string, flow string falls along in long string, thus cause secondary damage and the formation damage of oil production equipment, simultaneously, along with the degree of depth of current oil well is increasing, the size of long string is more and more less, thus it is larger to oil production equipment damaged condition, salvage difficulty and salvage cost also higher.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides one conveniently to carry out underground work, and joint self has good structural oil well safety joint.
To achieve these goals, the technical solution adopted in the utility model is such: oil well safety joint of the present utility model, comprise joint body, sheath is coated with outside joint body, sheath being removable is connected on joint body, vertically tube connector is installed in joint body, tube connector adopts scalable connecting pipe structure, tube connector top is arranged through joint body, tube connector is laterally provided with connecting axle, connecting axle two ends are all fixed on joint body, and tube connector is provided with boss near bottom place, one-body molded between boss and tube connector.
Further, as a kind of concrete form of structure, boss described in the utility model has guiding gutter.
Further, as a kind of concrete form of structure, the axial angle of guiding gutter bearing of trend described in the utility model and described boss is 45 degree.
Further, as a kind of concrete form of structure, jacket thickness described in the utility model is at least between 0. five to one centimetre.
Further, as a kind of concrete form of structure, sheath described in the utility model adopts stainless steel structure material to make.
Further, as a kind of concrete form of structure, jacket surface described in the utility model is coated with wearproof structural tier.
Compared with prior art, the utility model has the advantage of: the safety joint of this oil well conveniently carries out underground work, joint self has good structural, barrier propterty is very strong, not easily be damaged, the problem that can effectively avoid joint to fall in long string, substantially increases usability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model; In figure: 1. joint body; 2. sheath; 3. tube connector; 4. connecting axle; 5. boss.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the utility model oil well safety joint as shown in Figure 1, comprise joint body 1, sheath 2 is coated with outside joint body 1, sheath 2 is detachably connected on joint body 1, in joint body 1, tube connector 3 is vertically installed, tube connector 3 adopts scalable connecting pipe structure, tube connector 3 top is arranged through joint body 1, tube connector 3 is laterally provided with connecting axle 4, connecting axle 4 two ends are all fixed on joint body 1, tube connector 3 is provided with boss 5 near bottom place, one-body molded between boss 5 and tube connector 3, described boss 5 has guiding gutter, the axial angle of described guiding gutter bearing of trend and described boss 5 is 45 degree, described sheath 2 thickness is at least between 0. five to one centimetre, described sheath 2 adopts stainless steel structure material to make, described sheath 2 Surface coating has wearproof structural tier.
Oil well safety joint of the present utility model conveniently carries out underground work, joint self has good structural, barrier propterty is very strong, not easily be damaged, the problem that can effectively avoid joint to fall in long string, substantially increases usability, described boss 5 has guiding gutter, the axial angle of described guiding gutter bearing of trend and described boss 5 is 45 degree, can better carry out guiding flowing, not easily produce absorption to the fluid of process; Described sheath 2 thickness is at least between 0. five to one centimetre; described sheath 2 adopts stainless steel structure material to make; described sheath 2 Surface coating has wearproof structural tier; barrier propterty can better be strengthened; have stainless steel and wear-resisting effect concurrently; substantially increase overall usability, protect safety during use.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff completely can in the scope not departing from this utility model technological thought, carry out various change and amendment, the technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
