Description
Technical field
The utility model relates to oil drilling drilling rod, specifically a kind of anti-Thread-sticking tool joint.
Background technology
At present, the normally API modular connection of tool joint that petroleum industry drilling well adopts, the advantage of this joint is according to API standard manufacture, and technology maturation, easily processes and detects, and cost is lower, is therefore applied widely.But also have a lot of shortcomings, its most outstanding shortcoming is exactly that thread gluing easily occurs, and is not suitable for complicated oil gas well mining simultaneously.
In order to improve bad this shortcoming of the anti-stick button performance of API standard tool joint, a lot of researchers have carried out research work.Find by prior art documents, China Patent Publication No. is CN 201826771U, open day is on May 11st, 2011, utility model patent name is called " a kind of air-tight anti-gluing drill pipe connector ", this patent is improved API standard tool joint, and the hermetically-sealed construction of joint, from the axial seal of only having of API, increases to two hermetically-sealed constructions, sealing performance been significantly enhanced, and makes internal and external threads joint be difficult for occurring thread gluing inefficacy.
Its weak point is: although this joint has improved the anti-stick button ability of joint, but be tapered thread joint due to what take, after joint is tightened, internal thread and external screw thread mesh together, often be screwed into a tooth and will form interference fit, make screw thread produce being still within the bounds of possibility of thread gluing phenomenon; In addition, the root place that external thread piece is meshed with inner thread piece is that bending angle transition easily causes stress to concentrate, and affects application life.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of anti-Thread-sticking tool joint, and this tool joint is simple in structure, easy to install, good sealing effect.
According to the technical solution of the utility model: a kind of anti-Thread-sticking tool joint, comprise female joint and the male joint being threaded with described female joint, it is characterized in that: on described female joint inner peripheral surface, be processed with internal thread, front end corresponding to described internal thread in female joint is provided with female joint the first slave station shoulder, the main shoulder of female joint successively, and the rear end corresponding to described internal thread in female joint is provided with female joint the second slave station shoulder; Described male joint is provided with the external screw thread matching with described internal thread, in male joint, corresponding to described externally threaded front end, be provided with male joint the second slave station shoulder, in male joint, corresponding to described externally threaded rear end, be provided with successively male joint the first slave station shoulder, the main shoulder of male joint; Described internal thread and external screw thread are cylindrical thread, and when female joint is connected in male joint, female joint the second slave station shoulder is resisted against on male joint the second slave station shoulder.
As further improvement of the utility model, between described female joint the first slave station shoulder and internal thread leading section, there is one section of level and smooth anchor ring, between female joint the first slave station shoulder and the main shoulder of female joint, form large, the interior young conical surface of collar extension.
As further improvement of the utility model, the root place of the main shoulder of described male joint is provided with a circle circular groove.
Technique effect of the present utility model is: the utility model product structure simple designs is reasonable, cylindrical thread by male joint and female joint designs, and efficiently solves when tightening joint, is often screwed into a tooth, will produce interference fit, a difficult problem for thread gluing phenomenon occurs; Meanwhile, this product adopts three torque shoulders designs, and button torque is mainly all acted on torque shoulder, and the improvement of this structure, makes this joint be convenient to draw button, make-up, spinner, thoroughly improves the anti-stick button performance of screw thread and has improved the bonding strength of joint.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise female joint 1, female joint the second slave station shoulder 2, internal thread 3, female joint the first slave station shoulder 4, the main shoulder 5 of female joint, male joint the second slave station shoulder 6, external screw thread 7, male joint the first slave station shoulder 8, the main shoulder 9 of male joint, male joint 10, anchor ring 11, circular groove 12 etc.
As shown in Figure 1, the utility model is a kind of anti-Thread-sticking tool joint, comprise female joint 1 and the male joint 10 being threaded with described female joint 1, on described female joint 1 inner peripheral surface, be processed with internal thread 3, front end corresponding to described internal thread 3 in female joint 1 is provided with female joint the first slave station shoulder 4, the main shoulder 5 of female joint successively, and the rear end corresponding to described internal thread 3 in female joint 1 is provided with female joint the second slave station shoulder 2; Described male joint 10 is provided with the external screw thread 7 matching with described internal thread 3, front end corresponding to described external screw thread 7 in male joint 10 is provided with male joint the second slave station shoulder 6, and the rear end corresponding to described external screw thread 7 in male joint 10 is provided with male joint the first slave station shoulder 8, the main shoulder 9 of male joint successively; Described internal thread 3 is cylindrical thread with external screw thread 7, and when female joint 1 is connected in male joint 10, female joint the second slave station shoulder 2 is resisted against on male joint the second slave station shoulder 6.
Between described female joint the first slave station shoulder 4 and internal thread 3 leading sections, there is one section of level and smooth anchor ring 11, the length of this anchor ring 11 is about the length of 7 two tooth forms of two external screw threads, when male joint 10 and female joint 1 are fastenedly connected, anchor ring 11 is in external screw thread 7 outsides, top; Between these anchor ring 11 female joint first slave station shoulders 4 and the main shoulder 5 of female joint, form large, the interior young conical surface of collar extension, when male joint 10 and female joint 1 are fastenedly connected, the main shoulder 5 of female joint is resisted against on main shoulder 9 end faces of male joint.
The root place of the main shoulder 9 of described male joint is provided with a circle circular groove 12, by circular groove 12 is set, can effectively avoid stress to concentrate, and improves product whole service life.
The utility model is when male joint 10 and female joint 1 are fastenedly connected, and female joint the first slave station shoulder 4 leans and contacts with male joint the first slave station shoulder 8, and female joint the second slave station shoulder 2 leans and contacts with male joint the second slave station shoulder 6, and produces interference, shares button torque.
The utility model product internal thread 3 is all designed to cylindrical thread with external screw thread 7, is convenient to into button, draws button, thread alternating not, has solved when tightening joint, often be screwed into a tooth, internal thread 3 coordinates and will produce interference fit with external screw thread 7, and a difficult problem for thread gluing phenomenon occurs, and allows repeatedly to go up, shackle.
After the design's joint is tightened, the right angle torque shoulder in female joint 1 and the torque shoulder close contact in male joint 10, form interference fit, makes torque wrench moment Main Function in right angle torque shoulder, improves the ability of joint joint efficiency and stress corrosion resistant.Meanwhile, under the operation of interference torque wrench moment, circular bead surface plays good sealing function.
