Abstract
The present invention relates to an oil-increasing nipple joint capable of raising oil yield of oil well. It is formed from sucker rod subsituted, travelling valve and travelling valve seat, and mounted at connecting place of two sucker rods in the oil pipe positioned in the upper portion of oil well pump. When the sucker rod is moved downward in the oil pipe, the travelling valve is opened, and the crude oil can be smoothly passed through, and when the sucker rod is upward moved, the travelling valve is closed to seal oil channel, at the moment, the crude oil in the oil pipe can be lifted together with upward-moving sucker, rod, so that its production efficiency is raised, and the crude oil yield also is raised.
Description
Technical field
The present invention relates to a kind of oil well sucker rod substitute, especially can improve the Oil-increasing pup joint of oil well output.
Background technology
At present, known sucker rod substitute only plays the effect that centralizer is installed, and does not improve the functional oil that increases of oil well output.
Summary of the invention
In order to make sucker rod substitute have the functional oil that increases of raising oil well output, the invention provides a kind of Oil-increasing pup joint.This Oil-increasing pup joint makes down-hole crude oil move up with the upstroke of sucker rod by the on-off action of travelling valve.
The technical solution adopted for the present invention to solve the technical problems is: form Oil-increasing pup joint by sucker rod substitute, travelling valve, travelling valve seat, be installed in the junction of two sucker rods in the oil pipe, be positioned at the top of oil well pump.Action principle is: when sucker rod was descending in oil pipe, travelling valve was opened, and crude oil is passed through smoothly; When sucker rod was up, travelling valve was closed, the sealing oil duct, at this moment, the crude oil in the oil pipe with the upstroke of sucker rod by on carry, thereby, realized the raising oil recovery efficiency, increase the purpose of crude output.Travelling valve left rotation and right rotation successfully on sucker rod substitute can freely slide up and down again, can the switch oil duct, can set upright sucker rod again; Travelling valve is the annular of sealing, the travelling valve outer surface of upper has the projection and the groove of inclination 8-36 degree, and the quantity of projection and groove is 3-8, and the middle part of travelling valve has 3-8 oil-through hole, the bottom is cylindric, and the lower end surface of travelling valve can seal well with the travelling valve seat.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the vertical section constructional drawing of the embodiment of the invention.
Fig. 2 is a travelling valve top cross sectional representation, the A-A sectional drawing.
Fig. 3 is a travelling valve lower cross section schematic diagram, the B-B sectional drawing.
Fig. 4 is the duty sectional drawing of the embodiment of the invention in oil pipe.
In Fig. 1: 1. sucker rod substitute, 2. travelling valve, 3. travelling valve seat, 4. oil-through hole.
The specific embodiment
In Fig. 1, the upper end of sucker rod substitute (1) is a box thread, and with sucker rod male thread coupling, the lower end is a male thread, mates with rod collar; Travelling valve (2) freedom suit is at the middle part of sucker rod substitute (1), and have oil-through hole (4) in the middle part of self, travelling valve (2) top internal diameter is little, and the bottom internal diameter is big, the manufacturing process of travelling valve (2) is to adopt fiber reinforced nylon, and directly injection mo(u)lding is at the middle part of sucker rod substitute (1); Travelling valve seat (3) is cast in the lower end of sucker rod substitute (1), become one with sucker rod substitute (1), the external diameter of travelling valve seat (3) is greater than the internal diameter of travelling valve (2), and travelling valve seat (3) and travelling valve (2) cooperate, and forms a cover travelling valve assembly.Can find out that by Fig. 1 and Fig. 4 the course of work of the present invention is such: when sucker rod drives sucker rod substitute (1) when descending in oil pipe, travelling valve (2) with the effect of tubing wall frictional force and bottom oil pressure under upwards operation, break away from travelling valve seat (3), be that the travelling valve assembly is opened, the oil-through hole (4) that crude oil passes travelling valve (2) passes through smoothly along groove; When sucker rod substitute (1) is up, travelling valve (2) with the effect of tubing wall frictional force and top oil pressure under operation downwards, compress with travelling valve seat (3), be that the travelling valve assembly is closed, sealing crude oil passage, at this moment, the top crude oil of being sealed is up with sucker rod, finishes oil pumping process.
Claims (4)
1, a kind of Oil-increasing pup joint is made up of sucker rod substitute, travelling valve, travelling valve seat etc., and it is characterized in that: travelling valve is installed in the middle part of sucker rod substitute, and the travelling valve seat is installed in the bottom of sucker rod substitute.
2, Oil-increasing pup joint according to claim 1, it is characterized in that: travelling valve is the annular of sealing, the top internal diameter of travelling valve is little, the bottom internal diameter is big, travelling valve left rotation and right rotation successfully on sucker rod substitute, can freely slide up and down again, the travelling valve outer surface of upper has the projection and the groove of inclination 8-36 degree, the quantity of projection and groove is 3-8, the middle part of travelling valve has 3-8 oil-through hole, the bottom is cylindric, and the lower end surface of travelling valve can seal well with the travelling valve seat.
3, Oil-increasing pup joint according to claim 1 is characterized in that: the external diameter of travelling valve seat is greater than the internal diameter of travelling valve.
4, Oil-increasing pup joint according to claim 1 is characterized in that: travelling valve seat and sucker rod substitute form an integral body.
