Abstract
The invention relates to an oil extraction equipment component in the field of machinery, in particular to a universal conduction device of an oil pumping rod. A universal shaft is provided with a buttonhead which is relatively arranged in an axle hole arranged on a cylindrical shell, and positioning sleeves are arranged on both ends of the cylindrical shell through end covers. The universal conduction device of the oil pumping rod is connected with the oil pumping rod through a collar and a button-changing joint, and the universal conduction device is suitable for a horizontal well, an inclined well and a well with greater inclined angle. The universal conduction device has the effects of lopsided wear resistance, long service life, high crude oil yield and low operation cost.
Description
Technical field
The present invention is to provide the oil production equipment parts of mechanical field, specifically pumping rod universal conduction device.
Background technology
Before the present invention proposed, the sucker rod that is used for oil well was through box cupling or directly every sucker rod is interconnected, and formed rod string, by drive unit it was worked repeatedly up and down, reached the purpose of oil producing operation.But some hole condition because some oblique angle, position of pit shaft changes greatly, makes rod string when work and tube inner wall generation eccentric wear, causes sucker rod to come off or breaks the bar accident.
Summary of the invention
In order to overcome the existing direct-connected shortcoming of sucker rod, the invention provides a kind of pumping rod universal conduction device.This transmitter is installed universal drive shaft respectively by both sides in cylindrical shell and is solved the smooth and easy technical problem that penetrates the oblique angle borehole wall of sucker rod.
The scheme that technical solution problem of the present invention is adopted is: universal drive shaft is provided with bulb, and bulb is encased in the set axis hole of cylindrical shell relatively, and the cylindrical shell two ends are equipped with positioning sleeve by end cap.
Good effect is: pumping rod universal conduction device of the present invention by box cupling with become the snapping head and after sucker rod is connected, suit in the bigger hole condition of horizontal well, inclined shaft and rake angle, to use, have anti-eccentric wear, improve application life, increase crude output and reduce the effect of operating cost.
Description of drawings
Fig. 1 is a structure chart of the present invention
Among the figure, 1. universal drive shaft, 1.1. bulb, 2. end cap, 3. cylindrical shell, 4. positioning sleeve.
The specific embodiment
According to the figure, universal drive shaft 1 is provided with bulb 1.1, and bulb is encased in the set axis hole of cylindrical shell 3 relatively, and the cylindrical shell two ends are equipped with positioning sleeve 4 by end cap 2, and positioning sleeve makes the universal drive shaft at two ends remain on ad-hoc location in the cylindrical shell.
The bulb of universal drive shaft can rotate in cylindrical shell, thereby makes rod string keep connection status under the situation of decentraction.
Universal drive shaft can be connected with change snapping head with box cupling, and is connected with the sucker rod of all size.
The sucker rod transmitter is used for horizontal well, inclined shaft and the bigger hole condition of dog-leg degree to be used, and plays the effect of smooth and easy transition, can extend well depth down, makes oil well pump down to horizontal segment.Advantage with anti-eccentric wear, minimizing inspection pump number of times, raising oil recovery amount and reduction oil field operation cost.
