Abstract
A torsion type universal joint for horizontal well in workover on horizontal wells of oil fields comprises an spherical upper joint 1, an O-shaped seal ring 2, a steel ball 3, a spherical locking housing 4 and a spherical lower joint 5, wherein in the seal groove designed between the spherical upper joint 1 and the spherical lower joint 5 is positioned the O-shaped seal ring, the steel ball 3 is seated in the ball holder of the spherical lower joint 5 for mating the torsion groove of the spherical upper joint 1; then the spherical locking housing 4 is passed through the spherical lower joint 5 and connected to the screw at the lower end of the spherical upper joint 1. The utility model has overcome the difficulty the drilling tool has in settling down into well sections with large curvature that the torsional moment given by the rotary is very difficult to be transmitted to the drill head or milling tool, and can be widely used in horizontal well workover of oil fields.
Description
Technical field:
The utility model relates to the horizontal well moment of torsion formula universal joint that a kind of oilfield horizontal well heavy repair task is used.
Background technology:
Present oilfield horizontal well, owing to be subjected to the influence of wellbore trajectory, drilling tool often is difficult for being lowered to when being lowered to the big well section of curvature, and the moment of torsion of rotating disk output is difficult to all be delivered on drill bit or the milling tool, construction brings very big inconvenience to horizontal well.For this reason, we are through developing horizontal well moment of torsion formula universal joint repeatedly, and are good through trial effect.
Summary of the invention:
The purpose of this utility model provides a kind of horizontal well moment of torsion formula universal joint, and it is based on the bending that reduces drilling rod, is convenient to drilling tool and bores under net horizontal section and inclination section; The output torque of brill dish and rotating speed are delivered on drill bit or the milling tool by drilling rod; In milling, abundant circulating mud guarantees to return on the landwaste in the cooling of grinding tool and shaft bottom or the metal fillings and is developed into.It has solved the drilling tool that prior art exists and has been difficult for being lowered to the big well section of curvature, and the moment of torsion of rotating disk output is difficult to be delivered to problem on drill bit or the milling tool, and is good through test effect.
The technical scheme that its technical problem that solves the utility model adopts is: horizontal well moment of torsion formula universal joint is made up of spherical top connection, O RunddichtringO, steel ball, spherical lock sleeve, spherical lower contact; Give at the upper and lower joint of sphere and to put into the O RunddichtringO in the seal groove that stays, again 6 steel balls are put into the ball seat of spherical lower contact, then with after the torsional channel of spherical top connection cooperates sphere locking was covered spherical lower contact and spherical top connection lower end screwed connection.End play pressure testing 25MPa is adjusted in the assembling back, voltage stabilizing 15 minutes, and pressure drop is not more than 0.7MPa.
The beneficial effects of the utility model are, and are simple in structure, have the drilling tool of avoiding bending, fall low friction resistance, but transfer torque and the pressure of the drill can guarantee the normal circulation of mud to drill bit.
