Problems solved by technology

In this way, if the sealing performance of the packer rubber sleeve cannot meet the design requirements, then the seal between the packer rubber sleeve and the drill pipe cannot be tightly sealed, which will lead to blowout accidents and threaten the safety of operators

Embodiment Construction

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

[0022] figure 1 An embodiment of the test device 100 for the sealing performance of the packer rubber cartridge of the present invention is schematically shown.

[0023] The device 100 for testing the sealing performance of a packer rubber cartridge includes an experimental box 10 and an experimental drill pipe 20 accommodated in the experimental box 10 . like figure 1 As shown, when the packer rubber sleeve 30 is tested, the packer rubber sleeve 30 is put into the packer rubber sleeve 30 in a manner that it is sleeved outside the experimental drill pipe 20 .

[0024] The experimental box 10, the experimental drill pipe 20 and the packer rubber tube 30 can form a simulated packer, which is a model of the packer used in practice, and is used to simulate the real condition of the packer rubber tube 30 that is similar to that used in the well. surroundings.

Abstract

The invention relates to a device for testing sealing of a packer glue cylinder, comprising a test cabinet, a test drilling rod contained in the test cabinet and a first pressure control assembly communicating with the internal of the test cabinet. The packer glue cylinder is contained inside the test cabinet in a mode of sleeving the test drilling rod; the packer glue cylinder can be radially contracted and seated on the test drilling rod; a first pressure application cavity is formed on one side of the packer glue cylinder and is connected to the contact part of the packer glue cylinder and the test drilling rod; the first pressure control component is communicated with the first pressure application cavity; fluid is poured into the first pressure application cavity through the first pressure control assembly to squeeze the contact of the packer glue cylinder and the test drilling rod so as to test the sealing of the packer glue cylinder. Through the above arrangement, the device disclosed by the invention can effectively detect the sealing of the telescopic packer glue cylinder.

Description

technical field [0001] The invention relates to the field of drilling, in particular to a device for testing the sealing performance of a packer rubber cylinder. Background technique [0002] Blowout is a phenomenon in which fluid in a well (for example, oil) is ejected out of the wellhead uncontrollably under pressure. The packer rubber cylinder in the retractable packer is an important component to ensure the effective sealing of the packer, and is used to seal the wellhead to prevent blowout. However, only when the packer rubber sleeve is tightly sealed with the drill pipe at the wellhead can the occurrence of blowout accidents be effectively prevented, otherwise the effective plugging effect cannot be achieved. [0003] In the prior art, there is no special device for testing the sealing performance of the packer rubber cartridge of the retractable packer, and the retractable packer is usually used directly in the well. In this way, if the sealing performance of the pa...
