Novel injection head turning device

Abstract

The invention relates to a continuous oil pipe injection head, in particular to a novel injection head turning device. The device comprises a trailer base, an injection head base, a hydraulic oil cylinder, a rotary bracket and a rotary shaft, and is characterized in that: a cylinder body of the hydraulic oil cylinder is articulated with the trailer base; a hydraulic rod of the hydraulic oil cylinder is articulated with the middle part of the injection head base through an oil cylinder ear plate; and one end of the rotary bracket is fixedly connected with the trailer base, and the other end is connected with the edge part of the injection head base through the rotary shaft. The device can conveniently turn the injection head from an oblique state to a vertical position before the injection head is hoisted, thereby avoiding damage to the oil pipe and injection head caused by a large-angle bending of the continuous oil pipe generated when the injection head in the oblique state is directly hoisted. The novel injection head turning device provided by the invention is simple to operate and is easy to maintain as the hydraulic oil cylinder is convenient to assemble and disassemble; and the device realizes stable turning process and is safe and reliable.

Description

technical field [0001] The invention relates to a coiled tubing injection head, in particular to a novel injection head turning device. Background technique [0002] Coiled tubing technology is a new technology developing rapidly in the field of petroleum machinery, and it is more and more widely used in oilfield services. When the coiled tubing equipment is working, it is necessary to lift the injection head from the equipment and install it to the wellhead. Due to the height restriction during transportation, the injection head is generally placed on the trailer at an angle. In addition, for the convenience of operation, the coiled tubing is usually inserted between the injection head. Among them, when performing lifting operations, if the injection head is lifted directly when it is in an inclined position, the injection head will be unstable after being lifted, which will cause great damage to the oil pipe inserted into the injection head, and there is a great danger.

When the coiled tubing equipment is working, it is necessary to lift the injection head from the equipment and install it to the wellhead. Due to the height restriction during transportation, the injection head is generally placed on the trailer at an angle. In addition, for the convenience of operation, the coiled tubing is usually inserted between the injection head. Among them, when performing lifting operations, if the injection head is lifted directly when it is in an inclined position, the injection head will be unstable after being lifted, which will cause great damage to the oil pipe inserted into the injection head, and there is a great danger. In order to ensure safety, The best way is to turn the injection head to the vertical position before lifting, but there is no easy-to-handle turning device at present
