The utility model has the advantages that by arranging the eccentric wellhead upper seat and the pressure bearing, when the center of the horsehead rope of the oil pumping unit deviates, the center of the wellhead and the center of the horsehead rope can easily meet the requirements by rotating the eccentric wellhead upper seat, thereby effectively reducing the labor intensity and improving the labor efficiency; the utility model has the advantages of simple structure, stable performance and longer service life.
Description
Technical Field
The utility model relates to a technical field is adjusted to the well head, especially relates to an adjusting device for well head is eccentric.
Background
In the production process of the oil well, factors such as mechanical vibration, foundation sinking and the like cause the deviation of the center position of a well head center and a horsehead rope of the pumping unit, the coaxiality of a polished rod and the well head is reduced, the service life of a packing is slightly influenced, the polished rod wears an oil pipe seriously, the pumping unit is adjusted through moving, time and labor are wasted, the efficiency is not high, and the normal production work is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The object of the utility model is to provide an adjusting device for well head is eccentric just in order to solve above-mentioned problem.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides an adjusting device for well head is eccentric, includes eccentric well head upper bracket, well head lower base, pressure bearing and oil pipe, eccentric well head upper bracket install in on the well head lower base, be provided with between eccentric well head upper bracket and the well head lower base pressure bearing, oil pipe suit in eccentric well head upper bracket with in the well head lower base.
The utility model discloses it is preferred, eccentric well head seat of honour with vacuole formation between the base under the well head, pressure bearing install in the cavity.
The utility model discloses it is preferred, the upper end of eccentric well head seat of honour is provided with the sleeve, the sleeve with eccentric well head seat of honour integration shaping, and its one end put in the eccentric well head seat of honour.
The utility model discloses it is preferred, be provided with the screw thread on the telescopic inner wall, oil pipe suit in the sleeve, and through threaded connection.
The utility model discloses it is preferred, eccentric well head seat of honour with it is sealed through the sealing washer under the well head between the base.
The utility model discloses it is preferred, one side of base is connected with oil well top layer sleeve pipe under the well head.
The beneficial effects of the utility model reside in that:
the utility model has the advantages that by arranging the eccentric wellhead upper seat and the pressure bearing, when the center of the horsehead rope of the oil pumping unit deviates, the center of the wellhead and the center of the horsehead rope can easily meet the requirements by rotating the eccentric wellhead upper seat, thereby effectively reducing the labor intensity and improving the labor efficiency; the utility model has the advantages of simple structure, stable performance and longer service life.
Drawings
Fig. 1 is a schematic sectional structural view of an adjusting device for wellhead eccentricity.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1: the utility model provides an adjusting device for well head is eccentric, includes eccentric well head seat of honour 1, well head base 4, pressure bearing 2 and oil pipe 5 down, and eccentric well head seat of honour 1 is installed under the well head on base 4, is provided with pressure bearing 2 between eccentric well head seat of honour 1 and the well head base 4 down, and oil pipe 5 suit is in eccentric well head seat of honour 1 and well head base 4 down.
As shown in fig. 1, a cavity 9 is formed between an eccentric wellhead upper seat 1 and a wellhead lower base 4, a pressure bearing 2 is installed in the cavity 9, a sleeve 6 is arranged at the upper end of the eccentric wellhead upper seat 1, the sleeve 6 and the eccentric wellhead upper seat 1 are integrally molded, one end of the sleeve is arranged in the eccentric wellhead upper seat 1, threads 7 are arranged on the inner wall of the sleeve 6, an oil pipe 5 is sleeved in the sleeve 6 and is connected through the threads 7, the eccentric wellhead upper seat 1 and the wellhead lower base 4 are sealed through a sealing ring 3, and one side of the wellhead lower base 4 is connected with an oil well surface casing pipe.
As shown in fig. 1, when the center of the wellhead and the center of the horsehead rope are not concentric, the eccentric wellhead upper seat 1 is rotated to drive the oil pipe 5 to rotate on the pressure bearing 2, so that the center of the eccentric wellhead upper seat 1 and the center of the horsehead rope meet the requirement of coaxiality.
To sum up, the eccentric wellhead upper seat and the pressure bearing are arranged, when the center of the horsehead rope of the oil pumping unit deviates, the eccentric wellhead upper seat is rotated, so that the center of the wellhead and the center of the horsehead rope can easily meet the requirements, the labor intensity can be effectively reduced, and the labor efficiency is improved; the utility model has the advantages of simple structure, stable performance and longer service life.
The present invention can be implemented by various modifications without departing from the spirit and spirit of the present invention, and the above description is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, and all the equivalent structural changes made by using the contents of the present invention and the accompanying drawings are included in the scope of the present invention.
