Abstract

The invention discloses a test detecting tool for compression-type packer rubber sleeves. The test detecting tool comprises a center tube (1), a deblocking tube (24) and a canister-shaped hydraulic cylinder sleeve (10). The right end of the hydraulic cylinder sleeve (10) is in seal connection with the deblocking tube (24) by a canister-shaped connecting ring (16); a closed annular cavity (26) is formed between the hydraulic cylinder sleeve (10) and the deblocking tube (24); a canister-shaped piston (13) and a measuring ring (11) which is sleeved outside the deblocking tube (24) are disposed in the annular cavity (26); the piston (13) can push a baffle ring (5), a piston rod (7) and the measuring ring (11) to slide along the axis of the center tube (1); and a through hole (27) is disposed on the sidewall of the deblocking tube (24) and between the piston (13) and the connecting ring (16). The test detecting tool of the compression-type packer rubber sleeves not only can detect a plurality types of packer rubber sleeves, but also has the advantages of simple detection mode, high efficiency, high accuracy, low cost and the like.

Description

technical field [0001] The invention relates to a test and detection tool for a compression packer rubber cylinder used in an oil field. Background technique [0002] The packer is one of the essential tools in oil field production engineering, and the rubber cartridge is the core component of the packer. Therefore, the sealing performance of the packer rubber cylinder is the key to ensure the success of the packer. Conventional packers can be divided into compression and expansion types. In order to detect the rubber cartridge of the packer, Chinese patent CN2580434Y, published on October 15, 2003, discloses "Rubber cartridge pressure test device", and Chinese patent CN201372765Y, published on December 30, 2009, discloses " Packer rubber cartridge test device". However, the above-mentioned packer rubber tube test device has the disadvantages of low measurement accuracy and inconvenient use. Contents of the invention [0003] In order to solve the technical problem of ...
