Abstract
The utility model relates to a non-leakage hydraulic cylinder type oil well head device. Packing blockage is used for realizing sealing when an oil pumping unit runs, a beam hanger and packing frictionally move relatively, and absolute sealing cannot be realized; oil leakage of a well head causes waste of resources; and security incidents are easy to be caused due to eccentric wear of the beam hanger. A connecting clamp is arranged at the top of the non-leakage hydraulic cylinder type oil well head device, a sealing part puller bolt is disposed below the connecting clamp, and a sealing multistage cylinder is disposed on the periphery of the sealing part puller bolt; inner gasket slips are disposed between the connecting clamp and the beam hanger; a conical sealing sleeve is disposed at the lower end of the sealing part puller bolt; and the multistage cylinder moves along with vertical movement of the beam hanger. The multistage hydraulic cylinder structure can replace a traditional stuffing box, can completely seal an oil well head, and effectively prevents oil leakage incidents. The stage number and the specification of the hydraulic cylinder structure can be set according to actual stroke of an oil well, and installation is simple and convenient. Besides, after the non-leakage hydraulic cylinder type oil well head device is used with a universal stuffing box, the problem that the beam hanger is eccentrically worn can be effectively prevented, and the service life of the beam hanger is prolonged.
Description
Technical field
The utility model belongs to the oil extraction equipment technical field, is specifically related to a kind of no leak source hydraulic cylinder type well mouth of oil well device.
Background technology
Oil pumper is a kind of machinery equipment of recover petroleum, makes oil go out well through the way of pressurizeing.When the oil pumper upstroke, the oil pipe elastic shrinkage moves upward, and drives mechanical block-relief oil production device and moves upward, and the bump sliding sleeve produces vibration; Simultaneously, the copper current only valve cuts out, and reducing piston assembly shutoff oil is when the oil pumper down stroke, and the oil pipe elastic elongation moves downward, and drives mechanical block-relief oil production device and moves downward, and the bump sliding sleeve produces vibration; Simultaneously, reverse ball-and-seat is partly closed, and the reducing piston assembly is shutoff oil jacket ring shaped oil passage still, makes copper current only valve lower zone form negative pressuren zone, is equivalent to the stratum has been produced a powerful suction force.Because can't realize positive confinement, the well head oil leakage phenomenon is very serious, causes the waste of resource, and has polluted environment in running for oil pumper; Oil pumper beam hanger generation eccentric wear increases the power consumption of oil pumper, beam hanger is damaged even ruptures, and causes security incident.It is big that the oil recovery worker changes filler labour intensity, changes to come out give up that the filler processing is bad that environment is formed pollution again.
Summary of the invention
The purpose of the utility model provides a kind of no leak source hydraulic cylinder type well mouth of oil well device that can create sealed environment at the well mouth of oil well place at oil pumper beam hanger place.
The technical scheme that the utility model adopted is:
A kind of no leak source hydraulic cylinder type well mouth of oil well device is characterized in that:
Described no leak source hydraulic cylinder type well mouth of oil well device is set in the periphery that beam hanger is positioned at the well mouth of oil well place; Its top is provided with jointing clip, and the periphery that is provided with seal puller bolt seal puller bolt below the jointing clip is provided with the multi-stage oil cylinder of closed type.
Pad slips sheet in being provided with between described jointing clip and the beam hanger.
The lower end of described seal puller bolt is provided with cone-shaped sealed gland.
Top between the described oil cylinder at different levels is provided with the oil cylinder supporting pad;
Bottom between the oil cylinders at different levels is provided with jump ring;
The casing wall that removes outermost other oil cylinder is provided with oil cylinder oil transportation hole;
The casing wall of described outermost layer oil cylinder is provided with oil filler point, is provided with the oil filler point plug in the oil filler point.
The outer wall of described outermost layer oil cylinder is provided with hoisting ring.
The utlity model has following advantage:
The multistage hydraulic cylinder structure that the utility model designed replaces traditional blowout prevention box to use; Can well mouth of oil well be sealed fully; Avoid losing the sealing of well head, prevented the generation of oil leakage phenomenon effectively, guaranteed the tidiness of oil recovery environment because filler lost efficacy; The sum of series specification of hydraulic cylinder structure can be set according to the actual stroke of oil well, and simple installation uses flexibly, need not later maintenance; Be used in combination with universal blowout prevention box and can effectively prevent beam hanger generation eccentric wear, prolong the application life of beam hanger.
