Description
Technical Field
The utility model relates to the technical field of well control emergency equipment for oil and gas field exploration and development operation, in particular to a clamping device for a pilot cylinder of an out-of-control oil and gas well in oil and gas well emergency operation.
Background
Blowout runaway is the most serious industrial disaster in the petroleum exploration and development process, and seriously threatens the safety of operators, equipment, underground oil and gas resources and environment. The current common operation procedures for well control and rescue at home and abroad comprise the steps of removing obstacles near a wellhead, cutting remains of the wellhead, reconstructing the wellhead, killing the well and the like. Because high-intensity heat radiation (flame temperature is usually higher than 1500 ℃) is accompanied after blowout fires, personnel and equipment cannot approach near wellhead areas, and a fire striking cylinder and a matched tool are usually utilized for emergency operation to guide blowout fluid (oil, gas, drilling fluid, fire and the like) to the upper side, so that safety of the personnel and equipment near wellhead is guaranteed.
In the prior art, a pilot cylinder is covered above a residual flange of a runaway well in a mode of feeding a long-arm excavator or a long-arm mast, and once the upward jacking force generated by the impact of the fluid of the well bore of the runaway well is larger than the dead weight of the pilot cylinder, the pilot cylinder is difficult to cover on the residual flange of a wellhead. The design objective of the clamping device is to ensure that the position of the ignition cylinder in the uncontrolled oil and gas well is stable and reliable. It is typically comprised of a solid support frame, clamp, or other securing means to prevent the squib from shifting or rocking under high pressure, high temperature and extreme conditions. The stable igniting cylinder position is important for correctly igniting the sprayed oil gas, so that the high-pressure oil gas is safely consumed, and the continuous increase of wellhead pressure is avoided.
The Chinese patent document with the authority notice number of CN216642065U and the authority notice date of 2022, 5 and 31 discloses a three-branch igniting cylinder clamping and transferring device, which is provided with three igniting cylinders with different sizes and specifications, wherein the three igniting cylinders are arranged on a central main shaft and distributed on the periphery of the central main shaft. When the device is used, the ignition cylinder with the corresponding size is selected by rotating the proper placement angle according to the accident wellhead, and the ignition cylinder is fixed through the fixing bolt after being connected with the hanging sleeve. According to the accident scene condition, the height of the igniting cylinder is adjusted, and the heights of the other two igniting cylinders are adjusted, so that the center is ensured to be stable. After the whole equipment is connected, the whole equipment is subjected to trial hoisting, and the hoisting stability of the whole equipment is ensured by adjusting the sizes of the balancing weights and the hoisting steel wire ropes. In the process of the releasing, a steel cable and a winch are connected in an auxiliary traction ring to assist the releasing of the whole equipment. The scheme has the advantages that: 1. position adjustment can be efficiently and rapidly performed; 2. the device is applicable to igniting barrels with various sizes.
However, the above technical solutions have many problems: on the one hand, when an accident occurs, the wire rope is burnt at a high temperature on site (the flame temperature is usually higher than 1500 ℃), and the wire rope is broken or even broken; on the other hand, as the natural gas development intensity increases, more and more high-pressure high-yield wells have the risk of blowout out of control, once blowout out of control, the overhead force on the well head can be increased in geometric multiple, and the practical problem that the cover igniting cylinder is difficult can not be fundamentally solved by increasing the balancing weight.
