Embodiment 1

[0024] In order to overcome the problem that in the existing compression packer rubber cartridge experiment, a set of packer prototypes should be scrapped for each experiment, the experiment cost is high, and the problem of time-consuming is long, this embodiment provides a method such as figure 1 , figure 2 and image 3 The compression packer rubber cylinder experimental device shown includes a pressure-bearing cylinder 1, a mandrel 3, an upper joint 7, a hanger 9, and an extension cylinder 12. The pressure-bearing cylinder 1 is a circle with a closed lower end and an open upper end. The cylinder body, the side of the outer wall of the pressure-bearing cylinder 1 is provided with a liquid inlet hole 2, the mandrel 3 is placed in the pressure-bearing cylinder 1, the outer wall of the mandrel 3 is sleeved with a rubber cylinder 4 and an upper joint 7, The upper end of the rubber tube 4 is separated from the lower end of the upper joint 7 by a spacer 26, and the upper end of t...

Embodiment 2

[0034] On the basis of Example 1, such as figure 1 As shown, the assembly process of the compression packer rubber cartridge experimental device of the present invention is as follows: the rubber cartridge 4 of the compression packer and the spacer ring-5 are as follows figure 1 Put them on the mandrel 3 in turn, the number of rubber tubes 4 and spacer 1 can be changed; then connect the upper joint 7, the hanger 9, and the extension tube 12 with threads, put them on the mandrel 3, and tighten the pressure ring 13. Make the rubber tube 4 and the spacer ring 5 closely fit, but the rubber tube 4 is not compressed; then put the assembled mandrel 3 into the pressure-bearing tube 1, make the tapered surface of the hanger 9 and Fit the conical surface of the pressure-bearing cylinder 1, and tighten the top cap 11; finally, connect the liquid inlet 2 to the corresponding high-pressure pipeline.

[0035] Such as figure 1 As shown in the assembled experimental device, the high-pressur...

Abstract

The invention particularly provides an experimental device for a rubber cylinder of a compression packer. The experimental device comprises a pressure bearing cylinder, a mandrel, an upper connector, a hanger and an extension cylinder, wherein the pressure bearing cylinder is a cylinder body with the lower end closed and the upper end open; liquid inlet holes are formed in the side surface of an outer wall of the pressure bearing cylinder; the mandrel is arranged in the pressure bearing cylinder; an outer wall of the mandrel is connected with the rubber cylinder and the upper connector in a sleeving manner; the upper end of the rubber cylinder and the lower end of the upper connector are separated via a second spacer; the upper end of the upper connector is connected with the hanger; the two ends of the hanger are cylindrical; a middle section of the hanger is frustum-cone-shaped; the upper end of the hanger is connected with the extension cylinder; the upper end of the mandrel is connected with a pressing ring via screw threads; the lower end surface of the pressing ring clings to the upper end surface of the extension cylinder; the upper end of the extension cylinder is connected with a pressing cap; an inner wall of the upper end of the pressure bearing cylinder is connected with a top cap; the lower end surface of the top cap is pressed on a frustum cone surface of the hanger; and the extension cylinder is connected with the outer wall of the mandrel in a sleeving manner. The experimental device can simulate working processes such as sealing, unsealing, pressure bearing and packing of the rubber cylinder of the compression packer, thereby providing reference for selection and optimization of the packer and the rubber cylinder.

Description

technical field [0001] The invention specifically relates to an experimental device for a compression packer rubber cylinder, which is suitable for performance experiments such as pressure bearing, sealing and fatigue of the compression packer rubber cylinder. Background technique [0002] In the traditional compression packer rubber tube experiment, the assembled packer is generally lowered into the simulated wellbore, the packer is fixed, the packer is set, and the upper and lower chambers of the packer are subjected to a pressure test. A set of packer prototypes should be scrapped for this experiment, which is costly and time-consuming. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of high cost and long time consumption in the experiment of the existing compression packer rubber cylinder, in which a set of packer prototypes should be scrapped for each experiment. [0004] Therefore, the present invention provides a ...
