Description
Technical field
This utility model relates to technical field of petroleum machinery, a kind of petroleum pipeline tool screw thread locking device.
Background technology
In oil, natural gas resource exploration and development, petroleum pipeline tool is the middle bridge connecting ground with bottom hole resource.Petroleum pipeline tool is broadly divided in drilling engineering in the drilling rod of use, casing and cementing in the sleeve pipe and petroleum production engineering used the oil pipe used.
In drilling engineering, every drilling rod is connected by box and pin mutually head and the tail, forms drill string, provides the pressure of the drill and moment of torsion for being connected to the drill bit of drill string bottom, and provide drilling fluid that landwaste is carried out shaft bottom.In normally creeping into, drilling rod rotates forward, but when processing some down-hole accidents, needs to invert drilling rod.Inverting drilling rod easily makes the box and pin of jointed rod get loose, and therefore reversion drilling rod just requires to pull out of hole, and changes the box and pin drilling rod with reverse thread, again could invert drilling rod after lower brill.Accident treatment needs after terminating to rotate forward drilling rod, normally creeps into, and has to trip-out replacing forward drilling rod and goes into the well.For that process down-hole accident and the reversion drilling rod that carries out, it is necessary to make a trip for twice, for the well depth of thousands of meters, greatly waste drilling time.
In casing and cementing, setting of casing is also to have every sleeve pipe to use box and pin head and the tail to connect into well.Because hole anomaly, setting of casing is easily hampered, and needs to rotate and reverse combination and slides into well, improves cased efficiency.But reversion sleeve pipe the most easily makes the box and pin of connection sleeve pipe get loose, and causes down-hole accident.
Utility model content
For disadvantages mentioned above present in prior art, the purpose of this utility model is to provide a kind of petroleum pipeline tool screw thread locking device, and this device can fix the box and pin of drilling tool, and when preventing drilling rod from inverting, box and pin comes off, save drilling rod reversion and process the cycle of down-hole complex accident, reduce drilling cost；And be capable of sleeve pipe and rotate and reverse combination and slide into well, make setting of casing in hgher efficiency.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of locking device of petroleum pipeline tool screw thread, including box, pin thread, screw, it is characterized in that: on the circumferencial direction between the female thread and its end face of described box, be provided with one group of equally distributed screw, circumferencial direction between the external screw thread and its end face of described pin thread is provided with one group of equally distributed blind hole, described box is connected fixing respectively with pin thread by its female thread and external screw thread, and the screw on described box and the blind hole on pin thread are fixed by screw.
In technique scheme, the box of drilling tool is fixing with pin thread to be connected, and drilling rod rotates forward, and box can be more and more tighter with pin thread.When processing down-hole accident and needing drilling rod to invert, owing to there being the fixing of screw, box and pin thread will not get loose phenomenon.Therefore reversion drilling rod changes left-hand thread drilling tool without pulling out of hole, and saves the trip time, shortens drilling period.In the casing job of casing and cementing, every sleeve pipe head and the tail connect fixing, it is possible to make sleeve pipe rotate and reverse combination and slide into well, make setting of casing in hgher efficiency.
After in order to preferably realize technique scheme, the screw on described box is equal with the blind hole quantity on pin thread, equal diameters, and box and pin thread connection are fixed, each screw all can align with a blind hole.Box and pin can be made to get loose just the drilling rod reversion sufficiently large moment of torsion of generation makes screw be cut off, in order to improve the shearing strength of screw, can improve the quantity of screw, the quantity accordingly, as the screw on preferred described box and the blind hole on pin thread is 4-12.
Described screw can not exposure in the outer surface of box.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
Petroleum pipeline the most of the present utility model tool screw thread locking device, except being screwed in addition to connection of drilling tool box and pin itself, also uses trip bolt that box and pin is locked, prevents from rotating.
Petroleum pipeline the most of the present utility model tool screw thread locking device, is used in process drilling failure, need not make a trip and can be achieved with inverting drilling rod, shorten drilling period, reduce drilling cost.
Petroleum pipeline the most of the present utility model tool screw thread locking device, is used in setting of casing, it is possible to achieve sleeve pipe rotates and reverse combination and slides into well, makes setting of casing in hgher efficiency.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
The structure representing a kind of petroleum pipeline of this utility model tool screw thread locking device of Fig. 1 and Fig. 4 signal, including box 1, pin thread 2, screw 3.Described box 1 is threaded connection with pin thread 2, and when the petroleum pipeline tool using box and pin head and the tail to connect rotates forward, box 1 can turn tighter and tighter with pin thread 2, and will not release phenomenon.When petroleum pipeline tool rotates forward, box 1 can turn more loose and more loose with pin thread 2, be susceptible to the phenomenon that releases, and therefore pin thread 1 and box 2 also use screw 3 locked, prevents petroleum pipeline tool from rotating backward and releases.
As in figure 2 it is shown, be provided with one group of equally distributed screw 102 on the circumferencial direction between the female thread 101 and its end face of described box 1.As it is shown on figure 3, the circumferencial direction between the external screw thread 201 and its end face of described pin thread 2 is provided with one group of equally distributed blind hole 202.Described box 1 is connected fixing respectively with pin thread 2 by its female thread 101 and external screw thread 201, and the screw 102 on described box 1 and the blind hole on pin thread 2 202 are fixed by screw 3.
As shown in Figures 2 and 3, in order to make box 1 the most locked with pin thread 2, prevent petroleum pipeline tool from rotating backward and release.The quantity of the screw 102 on described box 1 and the blind hole 202 on pin thread 2 is 4-12.After screw 102 on described box 1 is equal with blind hole 202 quantity on pin thread 2, equal diameters, and box 1 and pin thread 2 connection are fixed, each screw 102 all can align with a blind hole 202.
Described screw 3 can not exposure in the outer surface of box 1.
Those of ordinary skill in the art will be appreciated that, above embodiment is intended merely to this utility model is described, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, change, the modification of embodiment described above all will be fallen in Claims scope of the present utility model.
