Abstract
The utility model discloses a lifting device for pipe drawing in oilfields. A lower cross beam and a trim mechanism are arranged on a working platform. The lower cross beam and a pipe drawing device arranged on the lower cross beam can be conveniently aligned in the position of a well mouth through the trim mechanism. A main hydraulic oil cylinder and two reinforcement hydraulic oil cylinder are respectively fixed at both ends of the lower cross beam. An upper cross beam is supported by the plungers of the oil cylinders. An upper and a lower slips are respectively arranged in the center cone holes of the upper cross beam and the lower cross beam. The utility model has the advantages of great pulling force, stable movement, non-shock, safety, high efficiency of pipe drawing working, etc.
Description
The utility model relates to a kind of oil field tube drawing lifting device, particularly a kind of tube drawing working machine with hydraulic pressure lift of step-up system.
Some is not fuel-displaced dried-up well in the exploratory well that oil field development is beaten, the oil field enters the middle and later periods exploitation also a collection of abandoned well can occur, a large amount of steel sleeve pipes are arranged under in these oil wells, be buried in undergroundly after well cementation, these sleeve pipes can be reused after underground extracting.Bit freezing also often taking place in drilling process and in the oil well operation process, block the event of running affairs, need get rid of these accidents with the method for drawing.In prior art, choosing is embedded in underground sleeve pipe, is stuck in drilling rod, oil pipe in the well, will runs derrick usually, utilizes hoist lifting device to choose, and operation in this way needs huger equipment, and relocation equipment and mounting cost are higher.And required lifting force is too big when just pulling out, and utilizes the operation of derrick formula lifting device dangerous again.Have a kind of hydraulic pressure of two cylinders to pull out jacketing machine in addition, can carry out this respect operation, but need very high hydraulic system pressure when just pulling out, manufacture difficulty is big.Just the big spoke degree of the loosening after load of tube drawing post reduces, and the power system power that is equipped with is bigger, can cause energy waste, improves operating cost.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, but provides a kind of multi-cylinder reinforcement hydraulic pressure to pull out the sleeve pipe working machine.
The utility model is by working platform, upper beam, bottom end rail, main hydraulic jack, auxiliary boosting oil cylinder and one-tenth, working platform top is provided with bottom end rail, the bottom end rail both sides are equipped with main hydraulic jack by flange, in the taper hole of bottom end rail middle part casing slip is installed, main hydraulic cylinder piston top links to each other with upper beam by bearing pin, and main hydraulic jack installed inside has auxiliary boosting oil cylinder; Bottom end rail on the working platform is provided with the adjustment of multidirectional screw rod reinforcement, locking device.
The utility model has the advantages that to have many hydraulic jacks boosting system, when just choosing operation, many hydraulic jacks are worked simultaneously, and total piston area of oil cylinder is big, can make to have the bigger power of pulling under the not high situation of hydraulic system pressure.Motion is relatively surely flat, does not have and impacts, and is safe and reliable.Tubing string does not need the excessive power of pulling after being pulled out and becoming flexible.By hydraulic control system the reinforcement hydraulic jack is quit work, the high-voltage oil liquid that hydraulic-pressure pump is discharged is all supplied with main hydraulic jack, has accelerated rising, the decline reciprocating speed of main hydraulic jack.Tube drawing operating efficiency height, the total output consumption of hydraulic system is steady.
Accompanying drawing 1 is the utility model master pseudosection.
Accompanying drawing 2 removes the plan view of upper beam part for the utility model.
Below in conjunction with accompanying drawing the utility model is further described, the working platform of tube drawing working machine of the present utility model is to be welded with shaped steel, is rectangular configuration.There is bottom end rail 2 at working platform 1 seat of honour, in the middle taper hole of bottom end rail casing slip 4 is housed, and is connected with two main hydraulic jacks 3 by flange on the bottom end rail.Upper beam 5 is connected by the piston rod of bearing pin with two main hydraulic jacks, drives upper beam in the time of the piston rod movement of oil cylinder and moves together, in the taper hole of upper beam middle part casing slip is housed also.Auxiliary boosting oil cylinder 6 is installed in the inboard of main hydraulic jack, and quantity is four, and per two is one group, is rigidly connected by needle beam.Bottom end rail on the utility model working platform is provided with the adjustment of multidirectional screw rod reinforcement, locking device 7, can be used to adjust the centering of casing slip and well head center hole in working at the scene, its quantity is 6, be distributed in as shown bottom end rail around, can adjust the position of bottom end rail either direction, convenient and reliable.
Working principle of the present utility model and operation process are achieved in that
Consult well history data, and in conjunction with utilizing Hooke's law, be subjected to elastic elongation amount and pulling force size under the pulling forcing state to calculate and check the well cementation position according to casing string, cut off with the method for explosion cutting sleeve pipe then position, cementing concrete ring slightly upper, with one section and the corresponding to technology bar of pipe fitting external diameter of will choosing, be connected on this tubing string top, the primer fluid oil-pressing pump makes piston rod stretch out the jack-up upper beam, the taper hole of upper beam central authorities makes upper slips block the technology bar and drives upwards rise of casing string, treat that hydraulic jack moves to after top dead center, the hydraulic jack commutation also drives the upper beam falling, this moment, upper slips unclamped, and the lower slips in the bottom end rail blocks casing string, and kept tubing string not fall, the hydraulic jack backhaul is to lower dead centre, finish a stroke, can extract a sleeve pipe behind reciprocal several strokes, utilize suspension rod that the sleeve pipe that sends is hung, shackle hangs out it, utilizes said method constantly will descend parts casing pipe progressively to extract again.
For realizing such scheme, make working platform base with certain loaded area with metal, can do the bottom end rail that fine position is convenient to make jig centrally aligned well head being equipped with on the working platform on working platform, each fixes a main hydraulic jack and several reinforcement hydraulic jacks the bottom end rail two ends.The plunger of these oil cylinders is supporting upper beam.In the center taper hole of upper and lower crossbeam upper and lower slips is housed respectively.During use, upper beam begins to move upward under hydraulic jack drives from lower dead centre, making upper slips in the upper beam block tubing string and drive tubing string together rises, rise to the commutation of after top dead center hydraulic jack, upper beam falls after rise thereupon, and lower slips blocks tubing string and keeps the position of tubing string, upper beam falls after rise to lower dead centre, begin second stroke, constantly to-and-fro motion just can progressively be extracted tubing string.
