Abstract
A leak-proof device of a pumping unit well mouth with pumping rod relates to a leak-proof device of the pumping unit well mouth, which aims at resolving the problems that the polish rods of pumping unit well mouths are abraded, oil pumping units need to do work to overcome the frictional resistance between packings and polish rods, and the produced liquid loses due to leakage at the well mouths. The small diameter end of a connector is sleeved with a locking ring through screwed joint and installed in an inner hole of a locking press cap, an O-shaped sealing ring is arranged in the locking press cap and located on the lower end of the connector, the lower end of a plastic spring tube is arranged in an inner hole of the large diameter end of the connector, the lower end of the plastic spring tube is installed in an upper connecting sleeve, and the small diameter end of a hemi-spherical sealing hopper is installed in the upper connecting sleeve and connected with the upper connecting sleeve through screw threads. The leak-proof device of the utility model is applied to the leakage control of the pumping unit well mouth with pumping rod.
Description
Technical field
The utility model relates to a kind of leak-proof device of rod-pumped well well head.
Background technology
Recover the oil and mainly still have the pumping unit of sucker rod in the oil field at present, this equipment is in oil recovery process, extraction liquid is in the annular space between beam hanger and oil pipe, when beam hanger moves up and down, can only rely on wellhead assembly top packing to prevent seepage, polished rod encapsulant in pumping easily is worn and very fast inefficacy, causes leakage.In order to solve the packing filling wearing and tearing, the oil recovery workman must frequently tighten or change encapsulant.Therefore, the working strength of workers of recovering the oil on the one hand is big and bring very big inconvenience to oil producing operation; On the other hand, cause the well head leakage to bring environment pollution owing to very easily missing, and owing between packing filling and the polished rod very big frictional force is arranged, thereby the energy consumption of pumping-unit motor increased.
The utility model content
The purpose of this utility model provides a kind of leak-proof device that has the rod-pumped well well head of sucker rod, with wearing and tearing, the oil pumper that solves existing rod-pumped well wellhead polish rod need overcome the frictional resistance between packing and the polished rod and do work, the energy consumption of the leakage of well head extraction liquid, pumping-unit motor brings environmental pollution problems greatly and because well head leaks
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described leak-proof device by under connect sealing device, the plastics spring pipe, hemispherical sealing funnel and upper joint sleeve constitute, described lower connecting device is by connector, retaining ring, O RunddichtringO and locking pressure cap constitute, the smaller diameter end of described connector is with retaining ring and by being threaded, the smaller diameter end of described connector is contained in the endoporus of locking pressure cap, described O RunddichtringO is contained in the locking pressure cap and is positioned at the lower end of connector, the lower end of described plastics spring pipe is contained in the endoporus of connector larger diameter end, the upper end of described plastics spring pipe is contained in the upper joint sleeve, and the smaller diameter end of described hemispherical sealing funnel is contained in the upper joint sleeve and with it and is threaded.
The utlity model has following beneficial effect: 1. the utility model has been realized the nothing wearing and tearing of rod-pumped well wellhead polish rod, and oil pumper does not need to overcome the frictional resistance between packing and the polished rod and does work; Well head does not have the leakage of extraction liquid, energy-conserving and environment-protective fully.2. when beam hanger pumps, because plastics spring pipe 2 is separated extraction liquid and sucker rod, thereby the extraction liquid of having avoided extracting out from oil well contacts with beam hanger, and extraction liquid does not contact with sucker rod, but the packing place does not have the liquid of seepage, thereby has reached the purpose of leakproof.When plastics spring pipe 2 moved up and down with beam hanger, compression stretching can not hinder the reciprocating motion of sucker rod simultaneously, therefore can not overcome beam hanger and 2 frictions of plastics spring pipe and the consumed power that does work because of need.
Description of drawings
Fig. 1 is a front view of the present utility model.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, the leak-proof device of present embodiment by under connect sealing device 1, plastics spring pipe 2, hemispherical sealing funnel 3 and upper joint sleeve 4 constitute, described lower connecting device 1 is by connector 5, retaining ring 6, O RunddichtringO 7 and locking pressure cap 8 constitute, the smaller diameter end of described connector 5 is with retaining ring 6 and by being threaded, the smaller diameter end of described connector 5 is contained in the endoporus of locking pressure cap 8, described O RunddichtringO 7 is contained in the locking pressure cap 8 and is positioned at the lower end of connector 5, the lower end of described plastics spring pipe 2 is contained in the endoporus of connector 6 larger diameter end, the upper end of described plastics spring pipe 2 is contained in the upper joint sleeve 4, and the smaller diameter end of described hemispherical sealing funnel 3 is contained in the upper joint sleeve 4 and with it and is threaded.The cross section of described plastics spring pipe 2 is circular, trapezoidal, T font or rectangle.
Operating principle: oil pumping polish rod proposes ground, to connect sealing device 1, plastics spring pipe 2, hemispheroid funnel 3 successively down through on the polished rod, descend connection sealing device 1 to be fixed on the polished rod and locking then, plastics spring pipe 2 penetrates polished rod, plastics spring pipe 2 with under be connected sealing device and be threaded, plastics spring pipe 2 is contained in the upper joint sleeve 4, and upper joint sleeve 4 is threaded with hemispheroid funnel 3, polished rod is lowered to promptly finishes this Unit Installation in the oil well.
