Problems solved by technology

[0003] In the existing technology, it is difficult to accurately detect the sealing performance of the rubber cartridge
Therefore, when the rubber cartridge is used for downhole operations, it is often encountered that the operation fails due to improper selection of the rubber cartridge
Due to the high cost of downhole operations and difficult operation, this kind of failure is very unfavorable and will have a very bad impact on the progress of downhole operations and the environment in the well

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] figure 1 The general structure of an embodiment of the device (hereinafter simply referred to as the device) 100 for testing the sealing performance of the rubber cartridge according to the present invention is schematically shown.

[0023] Such as figure 1 As shown, the device 100 includes a sleeve 12 and a mandrel 14 coaxially sleeved in the sleeve 12 . A substantially annular receiving annulus is formed between the sleeve 12 and the mandrel 14 . During detection, the rubber tube 13 can be tightly sleeved on the outside of the sleeve 12 . At this time, the rubber cartridge 13 will be in the containing annulus. In addition, the first pressing piece 9 and the second pressing piece 16 that seal the ends can also be respectively arranged at the two ends of the accommodating annular space, and the first pressing piece 9 and the second pressing piece 16 can carry out...

Abstract

The invention relates to a device for detecting packing property of a rubber sleeve. The device comprises a hollow sleeve, a central spindle, a first pressing piece, a second pressing piece and a first pressurization mechanism, wherein the central spindle is coaxially arranged inside the sleeve in a sleeving manner; a containing annulus is formed between the sleeve and the central spindle; the first pressing piece is arranged on one side of the containing annulus and can seal the containing annulus; the second pressing piece is arranged on the other side of the containing annulus and can sealthe containing annulus; the first pressurization mechanism is capable of pressurizing the containing annulus; at least one of the first pressing piece and the second pressing piece can move relative to the other of the first pressing piece and the second pressing piece. According to the device, the packing property of the rubber sleeve can be accurately detected.

Description

technical field [0001] The invention relates to the technical field of oil and gas well operation tool testing, in particular to a device for testing the sealing performance of a rubber cartridge. Background technique [0002] In oil and gas well operations, rubber cartridges are an important tool for sealing off the space in the well. Rubber cartridges are widely used in drilling and completion, workover and oil and gas production. The commonly used compression rubber cartridge can radially expand when its two ends are compressed, so as to realize the function of isolating the annular space in the well. [0003] In the prior art, it is difficult to accurately detect the sealing performance of the rubber cartridge. Therefore, when the rubber cartridge is used for downhole operations, it is often encountered that the operation fails due to improper selection of the rubber cartridge. Because the cost of downhole operation is very high and the operation is difficult, this ki...
