Description
Technical field
The utility model relates to the oilfield service equipment, and particularly a kind of device that is specifically designed to the operation of water flood recovery well servicing is a kind of automatically controlled snubbing serving device that surges.
Background technology
In original water injection well workover treatment process, be to carry out well workover after the emptying of water injection well internal pressure again, so both waste water resource and part crude oil also were unfavorable for environmental protection simultaneously.Main cause is that the water band in the oil well crude oil and is sprayed onto ground, can not recycling, the more important thing is that the oil well pressure emptying workover treatment cycle is long.
Present well head snubbing serving device, the execute-in-place inconvenience, duty cycle is long, the operating cost height.
The utility model content
The purpose of this utility model is: a kind of automatically controlled snubbing serving device that surges is provided, carry in the solution or down in the drain line process, sealing problem between tubing coupling projection and the ram block, and at the pressure of keeping in the process in the oil well of fetching and delivering of oil pipe, oil well pump, thereby realization Operating Pressure, the oil pipe that will keep in repair, oil well pump take out smoothly or are lowered to from the down-hole, reach the purpose that band is pressed maintenance, repair.
The technical solution adopted in the utility model is: the automatically controlled snubbing serving device that surges comprises that the full sealing liquid of double disc moves preventer, lower slips, electric control gear, the moving preventer of double disc half sealing liquid, side valve emptier and upper slips and forms.It is characterized in that: the top at the moving preventer of the full sealing liquid of double disc is connected with a lower slips, be connected with an electric control gear on the top of lower slips, be connected with the moving preventer of double disc half sealing liquid on the top of electric control gear, top at the moving preventer of double disc half sealing liquid connects an electric control gear again, be connected with a side valve emptier on the top of electric control gear, connect the moving preventer of double disc half sealing liquid on the top of side valve emptier again, be connected with a upper slips on the top of the moving preventer of double disc half sealing liquid.
It is fixedly connected that the full sealing liquid of double disc moves preventer, lower slips, electric control gear, the moving preventer of double disc half sealing liquid, electric control gear, side valve emptier, the moving preventer of double disc half sealing liquid, upper slips passes through flange from bottom to top in regular turn, and common central axis is arranged; Two the moving preventer of double disc half sealing liquid belows are respectively equipped with an electric control gear; Electric control gear top, top is provided with the side valve emptier.Utilize electric control gear to control the flashboard switch of adjacent two preventers, and control side valve emptier open or closed according to the requirement of construction, when realizing the tubing coupling projection and stop that pressure leaks in the oil well through ram block.
The surge operating principle of automatically controlled snubbing serving device: consult Fig. 1.
When workover treatment, the utility model is fixed on sleeve pipe or the tubing head, when last device for hoisting is carried on oil pipe, when the box cupling that connects between the adjacent oil pipe walked to electric control gear 3, electric control gear 3 commanded in regular turn that the moving preventer 4 of double disc half sealing liquid on top, side valve emptier 5 are closed, the moving preventer 4 of double disc half sealing liquid of bottom is opened; When the box cupling that connects between the adjacent oil pipe walked to the electric control gear 3 on top, the electric control gear 3 on top commanded in regular turn that the moving preventer 4 of double disc half sealing liquid cuts out, side valve emptier 5 is opened, the moving preventer 4 of double disc half sealing liquid on top is opened.Thereby realize that tubing coupling safety can keep the pressure in the oil well by preventer.In the process that promotes oil pipe, upper slips 6 plays fixedly oil pipe effect last carrying after process finishes; Lower slips 2 is that the utility model device plays fixedly oil pipe in installation, maintenance process.The moving preventer 1 of the full sealing liquid of double disc is to put forward process to finish the rear enclosed oil well on oil pipe.The different open and closes constantly of organic cooperation of each parts and preventer have realized that oil pipe and oil well pump take out oil well in the said process, and can keep the purpose of pressure in the oil well
The beneficial effects of the utility model: the utility model automatically controlled snubbing serving device that surges, carry on solving or down in the drain line process, sealing problem between tubing coupling projection and the ram block, and, realize Operating Pressure at the pressure of keeping in the process in the oil well of fetching and delivering of oil pipe, oil well pump.Advantages such as it is convenient, fast to have maintenance, repair, and it is effective to keep pressure, pollution-free.
