Description
Technical field
The present invention relates to petroleum works equipment technical field, it is a kind of environment-friendly type operation wellhead liquid collecting operating platform and its makes
Use method.
Background technology
There are following drawbacks in traditional light maintenance operation：
（1）Well head construction personnel is typically all to stand to operate on ground（The putting of tube rod, the installation etc. of well control device）, due to
All it is oil, water on the oil pipe inside and outside wall proposed out of well, if occurring, bleeder, which is not opened, oil pipe blocking, piston or pumping rod are disconnected takes off,
It often carries an oil pipe and just has tens liters of greases and come down in torrents to wellhead ground；It also will appear grease spilling in lower oil pipe operation, if
Casing liquid level in well head, per piece oil pipe of tripping in will overflowing liquid to wellhead ground, oil, water can pollute well head, ground, equipment
And tool, these can not only cause the pollution in well site, also cause ill effect to the operating environment of well head operating personnel（People stands
The operation in water, oil, mud）So that it needs constantly to clear up well head greasy dirt in operation process, and also needs to employment after operation
Power, material resources pollution administration, increase staff labor intensity, take a lot of work laborious.In addition, the crude oil overflowed permeates the ground and can not recycle,
Long-term operation crude oil is wasted than more serious.
（2）Hydraulic tongs are suspended in workover rig derrick side in traditional light maintenance operation, and often putting an oil pipe will lean on
The hydraulic tongs of man-driven kilogram weight more than 100 could carry out the upper shackle of oil pipe, and operating personnel are relatively elaborate.
（3）Because in such a way that double elevators put tubing string, often putting an oil pipe will lean on manpower lift to put elevator twice,
According to the inspection pump sump of measuring and calculating a bite two kms depth, only lifting drain line elevator just has tens tons of weight.If it is drilling rod is put, lift
The weight for putting drill pipe elevator is just more considerable.
Invention content
The present invention provides a kind of environment-friendly type operation wellhead liquid collecting operating platform and its application methods, overcome above-mentioned existing
The deficiency of technology can be solved effectively that existing for existing well head construction well site can be polluted, influence operating environment, cause crude oil unrestrained
Take, need to be cleared up, it is time-consuming and laborious, it is not easy to workover treatment, the big problem of labor intensity.
One of technical scheme of the present invention is realized by following measures：A kind of environment-friendly type operation wellhead liquid collecting operation
Platform, including waste collection tank, operating table surface, raising pipe nipple, preventer, air operated slips, protective fence and staircase, waste collection
The top plate of tank is known as operating table surface, and the leakage mesh that can be communicated with waste collection tank inner cavity is distributed in operating table surface, and waste liquid is received
Collection tank is fixedly arranged in the middle of raising pipe nipple, and the middle part for increasing pipe nipple is located at waste collection tank inside middle portion, increases the upper end of pipe nipple
Equipped with the upper flange above operating table surface, the lower end for increasing pipe nipple is equipped with the lower flange being located at below waste collection tank, on
It is installed with preventer and air operated slips on flange successively from the bottom to top；The periphery of operating table surface is equipped with protective fence, protection
Fence is equipped with the left forward side entrance positioned at operating table surface, and the operating table surface lower front side of the position of corresponding entrance is equipped with
Staircase.
Here is the further optimization and/or improvements to one of foregoing invention technical solution：

Hole is leaked to waste collection tank, and when there is contingency generation, operator is slid from operating table surface to ground by hang plate, and
It is separate as early as possible；
Third walks, and after the completion of shaft mouth operation, operator first withdraws preceding expansion board and rear expansion board, then prop up hang plate and make its with
Corresponding handrail guardrail forms limit, and ground is back to by staircase.
