Abstract
The utility model discloses a high pressure oil-gas water well operation device with pressure and consists of upper and lower beam of 1 and 12, upper and lower slips 2 and 3, left and right hydraulic cylinder 4 and 5, upper and lower ring-shaped sealer 6 and 10, a lifting short section 7, a hydraulic anti-sprayer 8, a regulating screw 9 and a drilling spool. The utility model has novel structure and is reliable. The utility model can repair the well of gas, oil and water under the circumstance of no blowout depressurizing or high density well pressure hydraulic well. Thus, the damage to the gas, oil and water well can be prevented and waste well can be utilized again to ensure excellent effect to oil field exploration.
Description
The utility model relates to a kind of particularly wellhead assembly of using of hydraulic oil, gas, well workover treatment of oil, gas, well that is used for.
At present, on-the-spot at oil, gas, well particularly when hydraulic oil, gas, well workover treatment, because the strata pressure height can't carry out Operating Pressure, carry out to guarantee underground work safety in order to prevent blowout, need take measures such as open flow step-down or raising well killing fluid density usually.But too high oil gas water well open flow step-down takes long even possibility for wellbore pressure; The well killing fluid density that adopts is restriction to some extent then, and well killing fluid density is too high easily to be killed oil reservoir, thereby this type of oil, gas, well is difficult to construction operation, causes long-term stopping production closing well, produces exploitation to the oil field and has serious consequences.
The purpose of this utility model is to provide a kind of and neither needs the open flow step-down, need not adopt the kill-job of high density well killing fluid again, and can guarantee hydraulic oil, gas, the well Operating Pressure device that workover treatment safety is carried out.
The utility model is to realize like this.This kind well control lifting appliance is made up of upper and lower crossbeam, upper and lower slips, left and right hydraulic cylinder, upper and lower ring packing device, hydraulic blow out preventer, lifting sub, well head four-way, adjustment leading screw, its structure, assembled relation are as follows: left and right two upright hydraulic cylinder upper and lowers fix by bolt and nut and bearing pin and horizontally disposed upper and lower crossbeam respectively, are respectively installed with sebific duct on the two hydraulic cylinder upper and lower part hydraulic oil joints and are connected with hydraulic control panel; Top rail below trend with it vertically is welded with upper slips, the lower transverse beam top is equipped with well head four-way, following ring packing device, hydraulic blow out preventer, lifting sub from the bottom to top successively, is gone up ring packing device and lower slips, wherein, the casing nipple that connects under the well head four-way penetrates in the lower transverse beam centre bore, be connected to each other with flange respectively between well head four-way, time ring packing device, hydraulic blow out preventer, the last ring packing device, lifting sub is sleeved on the tube connector between ring packing device and the hydraulic blow out preventer, and lower slips is welded on ring packing device upper end; Left and right hydraulic cylinder front side is respectively equipped with parallel with it adjustment leading screw, adjusts the leading screw opposite side and then is fixedly connected by upper and lower two horizontal righting rods and workover derrick.During work, this device is placed oil well or the well well head for the treatment of workover treatment, the lower transverse beam seat of this device is contained on the casing nipple, after will adjusting leading screw righting rod and workover derrick and being fixedly connected, can begin band and press workover treatment.In the workover treatment process, control on the Hoisting System that this device is made up of left and right two hydraulic cylinders, lifting sub and adjustment leading screw by the 3-position 4-way hand-operated direction valve on the operating hydraulically operated console and to carry or to transfer tubing string, and the sealing system that control is made up of upper and lower slips, hydraulic packing device, hydraulic blow out preventer guarantees that well head seals, and prevents blowout.Place the interior tubing plug of down-hole string then to play the effect of sealed well lower tubular column, the assurance workover treatment that matches with this device is carried out safely smoothly.
The utility model modern design, reliable operation, utilize it and down-hole oil tube blanking plug to match, can compress into capable workover treatment to high-pressure oil gas well band neither needing the open flow step-down need not adopt again under the situation of high density well killing fluid kill-job, avoid oil gas water well is damaged, " dried-up well " that be difficult to workover treatment for a long time brought back to life, guarantee that oil field development obtains good result, is suitable for and applies.
Fig. 1 is a structural representation of the present utility model.Fig. 2 is its lateral view.Among the figure, label " 13 " is the oil gas water well casing nipple.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
As shown in the figure, the utility model is made up of top rail 1, upper slips 2, lower slips 3, left hydraulic cylinder 4, right hydraulic cylinder 5, last ring packing device 6, lifting sub 7, hydraulic blow out preventer 8, adjustment leading screw 9, following ring packing device 10, well head four-way 11 and lower transverse beam 12.Wherein, top rail 1 and arranged on left and right sides is provided with and penetrates bolt the screw that left and right hydraulic cylinder is used is installed, lower transverse beam 12 central authorities are provided with the through hole of cover for seat Casing Failure pipe nipple, have with hydraulic cylinder lower end, the left and right sides on and arranged on left and right sides is welded with respectively to be connected and fixed the steel plate of using pin shaft hole.Upper and lower slips 2,3 adopt latus rectum Φ 120mm, in establish 1
