Abstract
The utility model provides a part of oil extracting devices in the field of machinery, in particular to a universal conductor of sucker rods, wherein a bulb is arranged on a cardan shaft, the bulb is correspondingly arranged into an axle hole arranged on a cylinder, and two ends of the cylinder are provided with locating sleeves through end covers. The universal conductor of sucker rods is suitable for being used in horizontal wells, oblique wells and wells with bigger oblique angles after connecting a coupling and a button-changing joint with a sucker rod, and has the effects of resisting one-side abrasion, prolonging the service life, increasing the yield of base oil, and reducing the operating cost.
Description
Technical field
The utility model provides the oil production equipment parts of mechanical field, specifically pumping rod universal conduction device.
Background technology
Before the utility model proposes, the sucker rod that is used for oil well is through box cupling or directly sucker rod is interconnected, and forms rod string, by drive unit it is worked repeatedly up and down, reaches 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 utility model 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 inclination borehole wall of sucker rod.
The scheme that the utility model technical solution problem 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: the utility model pumping rod universal conduction device 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 the utility model structure chart
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.
