Coiled-tubing safety rewinding and discharging device without auxiliary hydraulic motor

Abstract

The invention relates to a coiled-tubing safety rewinding and discharging device without an auxiliary hydraulic motor. The technical scheme includes that a tubing discharge power wheel drives a runnerto rotate under the rotation of a spindle, the gear of a tubing discharger is further driven to rotate through a tubing discharge driving chain, and the tubing discharger located outside the front side of a drum to operate; a reverser is connected with a forward and reverse screw to control the forward and reverse screw to rotate forwardly or reversely; a coiled tubing loaded by a coiled-tubing transition wheel is adjusted by the horizontal movement of a power ring. The coiled-tubing safety rewinding and discharging device has the advantages that the auxiliary hydraulic motor is omitted, onlya main hydraulic motor is remained, a hydraulic control line for the auxiliary hydraulic motor is removed, swinging of the hydraulic control line above the drum is avoided, and security hidden trouble brought by the hydraulic control line is eliminated; the operation side and the rotation side of the drum are distinguished, original mess is avoided, and service life of the coiled tubing is prolonged.

Description

technical field [0001] The invention relates to a coiled tubing arrangement device, in particular to a coiled tubing arrangement device without an auxiliary hydraulic motor for safe rewinding and arrangement. Background technique [0002] In oil extraction, coiled tubing has been widely used, and coiled tubing is a pipe made of low-carbon alloy steel with good flexibility, also known as flexible tubing. A roll of coiled tubing is several kilometers long and can replace conventional The tubing performs a lot of operations, and the coiled tubing operation equipment has the characteristics of pressure operation and continuous lifting. The equipment is small in size, fast in operation cycle and low in cost. [0003] However, in the use of coiled tubing, a tube rower is required for winding. If the arrangement is not adjusted during the winding process, it is easy to cause the coiled tubing to have different arrangement gaps and the phenomenon of winding and pressing the tube. On...

Problems solved by technology

[0003] However, in the use of coiled tubing, a tube rower is required for winding. If the arrangement is not adjusted during the winding process, it is easy to cause the coiled tubing to have different arrangement gaps and the phenomenon of winding and pressing the tube. Once it occurs, it cannot be adjusted, and it is extremely difficult. It is prone to defects such as crushing and scratching, which will damage its product quality; at the same time, due to the high strength of the coiled tubing, it cannot be arranged manually during the winding process, and the arrangement of the coiled tubing needs to be controlled by a tube arranger

[0004] The existing coiled tubing arrangement is in the form of a combination of mechanical transmission and hydraulic transmission. The screw is used to drive the actuator to move in the horizontal direction, and the auxiliary hydraulic motor is adjusted to realize the arrangement of the coiled tubing. Although , the installation of the auxiliary hydraulic motor can make the position adjustment of the coiled tubing very fast, but the existing problem is: the installation of the auxiliary hydraulic motor needs to add a hydraulic control line, and due to the needs of the site, the hydraulic control line generally adopts a hose line. The pressure is high, and the hose line often swings with the horizontal movement of the pipe row actuator, which will bring safety hazards to the operators; although the on-site operators will clamp the hose line at the level of the pipe row However, the hose line is still hanging on the side and front of the rotating pipe arrangement machine with open wires, which poses a great safety hazard
