Description
Technical field
The utility model belongs to the underground work instrument of petroleum industry, and particularly underground work ground oil pipe plays lower sled, is that underground work is drawn the isolated plant of delivering to well head with the ground oil pipe when removing oil pipe.
Background technology
At the oil well workover scene, removing oil pipe is daily operation, at present the ground oil pipe is drawn and deliver to well head, use jigger, jigger slides on the oil pipe track, the oil pipe track mostly uses two, three former well oil pipes as track, not only causes the waste and the consumption of tubing, and jigger is fixing not firm.Although taked many corrective measures, still can not stop the situation that jigger lands.No matter be that oil pipe is put on the jigger with artificial or machinery, all take off and be unable to do without the oil pipe slideway in addition, very easily damage oil pipe and external screw thread thereof.Its defective is: 1, jigger moves not steadily on the oil pipe track, along with the change of oil pipe center of gravity, particularly plays oil pipe and puts when single, and jigger slides not smooth sometimes, needs manually pulling, and oil pipe and jigger easily land and hurt sb.'s feelings like this, have potential safety hazard.2, ground is drawn and is sent the oil pipe personnel labor intensity big, and and then jigger runs back and forth; The oil pipe at well head place must reach certain height and just be convenient to the elevator of seting out when removing oil pipe, and when particularly playing oil pipe, every oil pipe needs also to need plural people to come lift to move with near the taboret of manually lifting to the well head as special operation, and labour intensity is big.3, will change the height of oil pipe track behind every next oil exit pipe, need the several people that the oil pipe track is raised adjustment, waste time and energy, labour intensity is big especially.4, cleaner production can not get ensureing, because artificial lift to move oil pipe, oil-pipe external wall crude oil and gloves skid, and needs to go crude oil lift to move again, the oil pipe of going into the well to be stained with soil and unclean foreign material with the soil stranding, easily causes pit shaft and oil reservoir contaminated.In sum, be badly in need of improving the glide that oil pipe removes.
Summary of the invention
The purpose of this utility model provides underground work ground oil pipe and plays lower sled, overcomes jigger and oversteps the limit and to land and adjust the level height of slide rail and the defective of gradient at any time according to the needs that remove oil pipe.Stop the possibility that jigger is overstepped the limit and landed, protect oil pipe body and external screw thread thereof to greatest extent, reduce working strength of workers, improve underground work efficient.
Technical solution of the present utility model is: underground work ground oil pipe plays lower sled and comprises jigger and slide rail; slide rail is a grider rail, is supported by the slide rail elevating mechanism, and jigger is placed in the slide rail; stop the possibility that jigger lands, effectively protect oil pipe body and external screw thread thereof.
Compared with prior art this device has following beneficial effect: slide rail elevating mechanism of the present utility model can be adjusted the level height and the gradient of flute profile slide rail, and the slide rail two ends are provided with the jigger limited block, stops jigger and lands.Jigger can be done wheel with bearing, make slide more smooth.Make jigger be easy to control and operation by jigger pulling mechanism, protect oil pipe body and external screw thread to greatest extent and effectively reduce working strength of workers, improve the underground work quality, realized safety in production, cleaner production.Its advantage has:
1, oil pipe draws and send steadily, and this device is special-purpose slideway, can realize good lubrication, plays an oil pipe and puts and well head place slide rail suitably can be heightened when single, and jigger slides smooth and easy in slide rail, when improving operating efficiency, has avoided rocking of hook block.2, safe and reliable, jigger slides in slide rail, have wire rope to connect and the slide rail two ends spacing, stopped oil pipe and jigger and landed the possibility of hurting sb.'s feelings, realized safety in production.3, improved operating speed, this device is also lifted the oil pipe pillow by cylinder, be convenient to the oil pipe upper and lower slide rail, can free lifting oil pipe to the well head desired height, reduced the distance that hook block is transferred, every next root oil pipe has reduced by 1 meter stroke, and every oil pipe is about 9.6 meters, can improve nearly 10% speed.4, greatly reduce working strength of workers, because the cylinder lifting oil pipe need not artificial lift to move oil pipe.But the lifting of slide rail free adjustment, when removing oil pipe, the oil pipe rear end can fall into jigger naturally or leave slide rail, realizes that the oil pipe afterbody is unattended.5, ensured the quality of the oil pipe of going into the well, used this device to need not artificial lift to move oil pipe, reduced pollution, protected down-hole facility and stratum, realized the target of cleaner production oil pipe.
