Abstract
The utility model discloses an oil, water, gas well operation string anti-jacking device, which comprises a box, a lower hinge, a screw rod, a two-way nut, a fixed bolt, upper hinges, a support, a center hinge, a valve and a cylinder body, wherein U-shaped openings are respectively arranged on the two ends of the support, the upper hinges are respectively arranged in the direction vertical to the U-shaped openings, the center hole is arranged on a central cylindrical cylinder body, the valve is arranged on the side surface of the central cylindrical cylinder body, the valve and the cylinder body are hinged through the center hinge, and the valve is locked through the fixed bolt. Forward threads and backward threads are arranged on the two ends of the two-way nut, the forward threads and the backward threads are connected with the O-shaped screw rod, the upper ends of the two-way nut is hinged with the support through the upper hinges, and the lower end of the two-way nut is hinged with the rectangle box through the lower hinge. The oil, water, gas well operation string anti-jacking device is simple in structure, convenient to mount, safe and reliable, is applied in various operations of oil, water and gas, meets an emergency for anti-jacking sealing wells and reduces sealing well time, puts an end to blowout accidents which happen because downhole strings lose control to upwardly jack, increases well control safety factors, protects safety of homework personnel and people property, reduces operation time, and increases oil and gas yield.
Description
Technical field
the utility model relates to anti-top of oil field Oil, Water, Gas well operations tubing string and blowout control technology, particularly is the anti-ejection device of a kind of Oil, Water, Gas well operations tubing string.
Background technology
Along with oil field development gets into the middle and later periods, the work operations amount constantly increases
, and a year operation Oil, Water, Gas well workload increases; According to requirement of safe production; According to the regulation of " oilfield downhole operation well control working instruction ", in playing the lower tubular column operation process, be the generation of prevention gas blowout accident; 2SFZ18-35 blowout preventer and blowout prevention plug valve be must be equipped with, oil sets annular space and tubing string space are used to seal; Rise in the lower tubular column operation process at oil-water well; Because tubing string has packer and major diameter instrument in the well, there are swab the well in effect or packing element distortion not to bounce back the oil that comes out in the stratum, gas, water pressure to the stratum; There is one to go up top power to tubing string; When last top power during greater than tubing string own wt and blowout preventer annular damper resistance, cause tubing string out of control up, head into derrick or bending and pound and cause the accident around dropping on well site and well head.
Summary of the invention
The purpose of
the utility model is exactly the above-mentioned defective that exists to prior art, designs the anti-ejection device of a kind of Oil, Water, Gas well operations tubing string.
The utility model is realized by following technical proposals:
the utility model comprises: square frame, following hinge, screw rod, two-way nut, set bolt, upper hinge, support, center hinge, valve, cylindrical shell.The support two ends of the anti-ejection device of its Oil, Water, Gas well operations tubing string respectively are provided with " U " shape opening; And on perpendicular to the direction of opening, respectively be provided with a upper hinge; The intermediate cylindrical cylindrical shell is provided with centre bore, blocks tubing coupling top short circuit, and the side is provided with valve; Center hinge, valve and cylindrical shell is hinged, and by set bolt valve is locked; Two-way nut two ends are that positive and negative screw thread is connected with the screw rod that is provided with "O; The upper end is hinged through upper hinge and support, and the lower end is through hinge and rectangular boxes are hinged down, and square frame hangs over the two ends of preventer; Regulate two-way nut, with the anti-ejection device tension of Oil, Water, Gas well operations tubing string.
The beneficial effect of
the utility model is: simple in structure, easy for installation, safe and reliable; Be applied to the Oil, Water, Gas well operations; Can meet an urgent need that anti-closedtop well, segmentation pressurization well-flushing, examination squeeze, pressure testing, heavy oil wells heat are washed, stop work temporarily and plug valve cooperates the short time shut-in well fixing etc., shortens the shut-in well time, has stopped in the well that tubing string is out of control goes up the generation that gas blowout accident is caused on the top; Improved the well control safety factor; Effectively protection operating personnel and property safety shorten the activity duration, increase oil, gas output.
