The background art comprises the following steps:
at present, there are a large amount of less output in domestic and foreign oil and gas field, the oil and gas well of production temporarily, need to carry out interim shutoff to these oil and gas wells, and can detect internal pressure at any time, the pressure release, consider that domestic oil field all carries out the water injection operation to the exploitation layer, abandonment oil well is behind the stratum pressure risees, the pressure can progressively be improved in the well, cause plugging device to bear certain pressure, still need consider simultaneously subsequent production, consequently still need consider to realize the pressure release function under sealed reliable prerequisite, present well head plugging device passes through flange bolted connection, the installation rate is slow and have the interior liquid outflow of well head to fall to the ground and cause the pollution not environmental protection, for the interior liquid that flows out of well head when reducing the installation plugging device, need install fast, the plugging device that pollution-free falls to the ground.
The utility model has the following contents:
in order to solve the problem that present well head plugging device installation rate is slow, there is pollution not environmental protection, the utility model provides a quick well head plugging device of environment-friendly.
The technical scheme of the utility model is that: the utility model provides a quick well head plugging device of environment-friendly, includes the shutoff pipe, and shutoff pipe lower part is the gland, and gland and well head flange pass through octagon sealed pad, clamp connection, through circular cone anchor ring sealing connection between shutoff pipe lower part and the circular cone head, circular cone head upper portion fixed connection adjusting lever, adjusting lever upper portion and shutoff pipe threaded connection, and shutoff pipe one side is connected with the pressure release pipe.
The piston is arranged on the adjusting rod on the upper part of the pressure relief pipe and is connected with the plugging pipe through a sealing ring in a clearance fit manner.
The plugging pipe extends upwards to form a section of anti-theft pipe, the top of the adjusting rod is provided with an irregular torsion hole, and the top of the anti-theft pipe is higher than the torsion hole.
The outer side of the pressure relief pipe is connected with a downward elbow and then connected with a male quick connector, and the specification of the quick connector is DN80.
The adjusting rod is connected with the conical head through a bearing, a retainer ring for a shaft and a retainer ring for a hole by a heat exchange sealing ring, and the conical head is provided with a sealing ring at the position of the conical sealing ring surface.
The utility model discloses following beneficial effect has: utilize former well head flange and octagon sealed pad, constitute seal structure with gland, clamp, the installation is quick, and is sealed reliable, when needing the pressure release, uses specialized tool to rotate the adjusting lever, and the circular cone head descends and to release the pressure, and the liquid that flows out is connected high-pressure hose through the pressure release pipe and is got into the sewage tank car, and the on-the-spot is pollution-free, and safety ring protects, simple structure, and sealed effectual.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-a plugging pipe, 2-a hoop, 3-a wellhead flange, 4-an octagonal sealing gasket, 5-a conical head, 6-a gland, 7-an adjusting rod, 8-a piston, 9-a torsion hole, 10-an anti-theft pipe, 11-a pressure relief pipe and 12-a quick joint.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
shown by figure 1, a quick well head plugging device of environment-friendly, including shutoff pipe 1, 1 lower part of shutoff pipe is gland 6, and gland 6 is connected through octagon sealed pad 4, clamp 2 with well head flange 3, through circular cone anchor ring sealing connection between 1 lower part of shutoff pipe and the circular cone head 5, circular cone head 5 upper portion fixed connection adjusting lever 7, adjusting lever 7 upper portion and the threaded connection of shutoff pipe 1, 1 one side of shutoff pipe is connected with pressure relief pipe 11.
On the upper portion of the pressure relief pipe 11, the adjusting rod 7 is provided with a piston 8 which is connected with the plugging pipe 1 through a sealing ring in a clearance fit manner, so that high-pressure liquid in a well mouth is prevented from overflowing from the threaded connection part of the adjusting rod 7 to cause environmental pollution and personal injury accidents.
The plugging pipe 1 extends upwards to form a section of anti-theft pipe 10, the top of the adjusting rod 7 is provided with an irregular torque hole 9, the top of the anti-theft pipe 10 is higher than the torque hole 9, the adjusting rod 7 cannot be rotated from the outside by using a tool, and the adjusting rod 7 can be rotated by only inserting the special 3-purpose tool into the torque hole, so that the anti-theft effect is achieved.
The outer side of the pressure relief pipe 11 is connected with a downward elbow and then connected with a male quick connector 12, the downward pipe connector can discharge liquid flowing out of a well mouth completely without residues, and the specification of the quick connector 12 is a DN80 high-pressure hose matching connector commonly used in oilfield workover treatment.
