Abstract
The utility model discloses an oil pipe drill rod rotating short section which comprises an upper joint, a check nut and a lower joint, wherein the upper joint is of a hollow structure, one end of the lower joint penetrates through the upper joint and is clamped and connected with one end of the upper joint, the check nut is in threaded connection in the upper joint, two groups of steel ball grooves are respectively formed in two sides of one end, close to the check nut, of the lower joint, and two groups of rotating steel balls are respectively and correspondingly arranged in the two groups of steel ball grooves. The rotary steel ball bearing realizes the rotary function between the oil pipe drill rod and the battery barrel through the two groups of rotary steel balls arranged between the upper joint and the lower joint, thereby releasing the rotary torque between the oil pipe drill rod and the battery barrel, and having simple structure, low price, easy processing and convenient installation.
Description
Technical Field
The utility model relates to the technical field of oilfield logging auxiliary instruments, in particular to a rotary nipple of an oil pipe drill rod.
Background
In the field of oil field well logging, torque is generated during the process of lowering and lifting a tubing and a drill pipe, but a logging instrument string is connected with an instrument which does not allow rotation (such as a multi-arm caliper logging instrument). If the tool rotates during logging due to the torque generated by the tubing or drill pipe, measurement errors and even damage to the tool can result.
To the above problem, an oil pipe drill rod rotary short section is developed, and the oil pipe drill rod rotary short section can be additionally arranged between an oil pipe drill rod and a battery barrel to release the rotary torque of an instrument string, so that the oil pipe drill rod and the battery barrel can rotate mutually.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a rotary nipple of an oil pipe drill rod, which aims to solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a rotatory nipple joint of oil pipe drilling rod, includes top connection, check fender nut and lower clutch, the top connection is hollow structure, the one end of lower clutch is passed the top connection and is connected with the one end block of top connection, check fender nut threaded connection is in the top connection, the one end both sides that the lower clutch is close to check fender nut are provided with two sets of steel ball grooves respectively, and are two sets of the steel ball inslot corresponds respectively and is provided with two sets of rotatory steel balls.
Further, the surface of the rotating steel ball is higher than the plane of the steel ball groove.
Furthermore, a spacing bulge is arranged between the two groups of steel ball grooves.
Further, the number of the rotating steel balls is 4.
Furthermore, one end of the upper joint is connected with an oil pipe drill rod.
Furthermore, one end of the lower joint is connected with the battery barrel.
Compared with the prior art, the utility model has the beneficial effects that: the rotary torque releasing device realizes the rotary function between the oil pipe drill rod and the battery barrel through the two groups of rotary steel balls arranged between the upper joint and the lower joint, thereby releasing the rotary torque between the oil pipe drill rod and the battery barrel, and has the advantages of simple structure, low price, easy processing and convenient installation.
