Problems solved by technology
This kind of tubing crossarm has no effect on the current manual tubing arrangement. With the rise of mechanized workover technology, if the mechanized discharge of tubing is realized, it will be difficult to realize mechanized tubing rowing due to the different inclination angles of each tubing in each row. with take tube

Embodiment Construction
[0016] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.
[0017] according to Figure 1-3 As shown, a kind of oil pipe cross arm that can be used for mechanized or automatic oil pipe discharge, the oil pipe cross arm body 2 can be any geometry, such as cylinder, cuboid, cube, etc., and the upper surface of the cross arm is provided with a groove 1, such as an arc groove , or a V-groove, or a groove of other shapes, the groove is used to place the oil pipe, restrict the rolling of the oil pipe, and fix the position of the oil pipe. The number of grooves is arbitrary and arranged evenly. If the grooves are circular arc grooves, the arc is not greater than 180 degrees. If the grooves are V-shaped grooves, the upper surface of the cross arm after the oil pipe is placed should n...

The invention discloses an oil pipe cross arm, comprising a cross arm body. The upper surface of the cross arm body is provided with groovse. The groove is used to place an oil pipe to limit rolling of the oil pipe and make the position of the oil pipe fixed. The design principle of the groove is that the size of the groove does not influence taking and placing of the oil pipe and placing of an upper layer oil pipe cross arm. The center distance of two adjacent grooves should make a certain gap between the two adjacent oil pipes, and the oil pipes do not disturb each other when being taken or placed. The cross arm is provided with a cross arm positioning device, so that after the oil pipe cross arm is installed, the positions of the upper layer oil pipe cross arm and the lower layer oil pipe cross arm are consistent, that is, the vertical projections of the upper layer oil pipe cross arm and the lower layer oil pipe cross arm in the grooves in the same position are overlapped. The oil pipe cross arm can realize accurate positioning when oil pipes are arranged, and is beneficial for realizing mechanization and automation of oil pipe arrangement.
Description
technical field [0001] The invention relates to oil pipe discharge technology, in particular to an oil pipe cross arm. Background technique [0002] At present, during the workover operation of conventional oil and water wells, it is necessary to manually discharge the tubing. The discharge of the tubing is mainly in the form of horizontal discharge. The cross-arm between layers of oil pipes, this cross-arm erection method makes good use of on-site resources and realizes the discharge of oil pipes. When the oil pipe is discharged, the coupling at one end of the oil pipe is aligned. Because the outer diameter of the oil pipe body and the oil pipe coupling is different, for example, the body of the 27 / 8in oil pipe is φ73mm, the outer diameter of the oil pipe coupling is φ89mm, and the cross arm of the oil pipe is a smooth cylindrical surface , with the increase of the number of pipes, the end of the oil pipe body of each layer is inclined to the beginning of the pipe. This k...
