Abstract
The utility model relates to an oil drilling tool, in particular to a cardan universal joint for rotary guiding drilling which comprises a body (1), a polyhedral short joint (2), a columnar pin (3) a center pipe (4), wherein a polyhedral hole is arranged in the body (1), a polyhedral short point (2) is installed in the polyhedral hole, and a radial through-hole is arranged in each edge of the polyhedral short joint (2). Each hole is provided with a columnar pin (3) and a groove is milled on one tip of the columnar pin (3). A spherical bond structure is arranged on the center pipe (4) and the groove of the columnar pin (3) is jammed on the bond. The utility model utilizes simple structure design, when the body (1) is rotating, the polyhedral short joint and the columnar pin transfer the rotation torque of the body (1) to the center pipe and the center pipe can swing up and down along its centre of sphere and swing along the axial cord of the columnar pin (3) to achieve the purpose of swinging in arbitrary direction.
Description
Technical field
The utility model relates to a kind of oil drilling tool, especially a kind of rotary steerable drilling universal joint.
Background technology
Rotary steerable drilling promptly can change the well drilling direction at any time on ground, and Controlling Borehole Trajectory realizes rotary drilling continuously, improves drillng operation efficient.Realize rotary steerable drilling need a kind of can transfer torque, can realize again towards the instrument of any direction swing.
Summary of the invention
The purpose of this utility model be to provide a kind of can transfer torque, rotary steerable drilling universal joint that again can any direction swing.
The technical solution of the utility model is as follows: mainly be made up of body 1, polyhedron pipe nipple 2, pin 3 and central tube 4, a multiaspect body opening is arranged in body 1, polyhedron pipe nipple 2 is installed in the multiaspect body opening, on each bar limit of polyhedron pipe nipple 2, a radial direction through hole is arranged all, pin 3 all is housed in each hole, one end mill of pin 3 has groove, and a spherical bond structure is arranged on central tube 4, and the groove of pin 3 just is stuck on the key.
The utility model adopts simple structure design, and when body 1 rotation, polyhedron pipe nipple 2 is passed to central tube 4 with pin 3 with the driving torque of body 1; Central tube 4 can be swung around the upper and lower swing of its centre of sphere with around the axis of pin 3 simultaneously, thereby reaches the purpose of any direction swing.
