Description

A kind of coiled tubing winds safely the application method of pipe racking device
Technical field
The present invention relates to a kind of application method of pipe arrangement device of continuous oil pipe, in particular to a kind of coiled tubing is wound safely The application method of pipe racking device.
Background technique
In oil exploitation, coiled tubing has been widely available use, and coiled tubing is made of low-carbon alloy steel Tubing, there is good flexibility, also known as coiled tubing, and the long several kms of a roll of coiled tubing can replace conventional oil pipe and carry out very much Operation, continuous oil pipe operation equipment have the characteristics that Operating Pressure, continuously remove, and equipment volume is small, and duty cycle is fast, cost It is low.
But in coiled tubing in use, needing racker to be wound, during the winding process if do not adjusted The phenomenon that arrangement, it is different to be easy to appear coiled tubing aligned gaps, winds pressure pipe, once occur will be unable to adjust, and easily There is the defects of squeezing wound, scratching, damages its product quality;Simultaneously because coiled tubing intensity is high, during arranging winding It can not manually be arranged, need to control the arrangement of coiled tubing by racker.
Existing pipe arrangement device of continuous oil pipe is machine driving and the form that hydraulic drive combines, and is passed by lead screw It is dynamic to drive the movement of comb executing agency horizontal direction, and be adjusted by auxiliary hydraulic motor, to realize coiled tubing Comb, although, installation auxiliary hydraulic motor the position of coiled tubing can be made to regulate the speed quickly, there are the problem of It is:Installation auxiliary hydraulic motor needs to add hydraulic control line, and due to the needs at scene, hydraulic control line generally uses hose Line, since pressure is larger, soft pipeline often moving horizontally and swing with comb executing agency, this will be to operator Bring security risk;Although on the cross bar for the horizontal direction that soft pipeline can be clipped in racker by clip by site operation personnel, But soft pipeline is still the side and front for the tube drawbench that open-wire line is hung in rotation, this there is very big security risk.
Summary of the invention
The purpose of the present invention is to drawbacks described above of the existing technology, provide a kind of coiled tubing safety winding row The application method of pipe device, eliminates original auxiliary hydraulic motor, provides power to eliminate for auxiliary hydraulic motor The hydraulic line to swing back and forth, to eliminate security risk caused by soft pipeline is swung because of high pressure;In addition, by from comb The driving wheel of machine draws power to comb executing agency, directly controls lead screw and carries out positive and negative rotation, drives the dynamic ring water on lead screw It square to positive and negative movement, and then drives coiled tubing transition wheel group and coiled tubing horizontal direction to be wound mobile, realizes Position adjustment when coiled tubing is wound.
A kind of coiled tubing that the present invention mentions winds safely the application method of pipe racking device, includes the following steps:
The first step, roller rotate and drive racker main body(a)Synchronous working:
In roller(18)Center install master gear(19), master gear(19)Drive main shaft(20)Rotation, in main shaft(20)In The heart is equipped with comb power wheel(21), in roller(18)Side be equipped with comb in runner(22), lift arm(23.1)With lifting liquid Cylinder pressure(25), lifting hydraulic cylinder(25)Bottom be fixed on bracket(14)On, top and lift arm(23.1)It is flexibly connected, passes through Lifting hydraulic cylinder(25)Drive lift arm(23.1)Lifting;In lift arm(23.1)Outer end be equipped with racker main body, lifting Arm(23.1)Inner cavity install comb driving chain(23), comb driving chain(23)One end is wound on runner in comb(22), separately One end is wound on the gear of racker main body(24), comb power wheel(21)In main shaft(20)Rotation under drive comb in runner (22)Rotation, passes through comb driving chain(23)It is further driven to the gear of racker main body(24)Rotation is located to drive Roller(18)Front outside racker main body(a)Work;
Second step, racker main body drive coiled tubing to move horizontally:
