The invention provides a test detection tool for a high temperature packer glue cylinder. The test detection tool for the high temperature packer glue cylinder includes a column assembly, a pressure transmission assembly and a hydraulic cylinder jacket. The column assembly is provided with an installation section for installation of a detected glue cylinder; the pressure transmission assembly sleeves outside the column assembly, the left end of the pressure transmission assembly is located at the right end of the installation section, and the pressure transmission assembly can slide along the axial direction of the column assembly; and the hydraulic cylinder jacket is arranged outside the column assembly, the right end of the pressure transmission assembly is provided with a piston, the piston is arranged between the hydraulic cylinder jacket and the column assembly, the hydraulic cylinder jacket, the piston of the pressure transmission assembly and the outer wall of the column assembly form a sealed space; and the sealed space can expand and drive the pressure transmission assembly to slide along the axial direction of the column assembly. The test detection tool for the high temperature packer glue cylinder can reach the purpose of testing the driving force of a high temperature expanding agent.
Description
technical field [0001] The invention relates to a high-temperature packer rubber cylinder test and detection tool. Background technique [0002] The main function of the packer is to separate the production layer and the construction layer from each other, so as to prevent the interference of fluid and pressure between layers. The advantages and disadvantages of the packer are mainly reflected in the sealing performance. As the sealing element of the packer, the rubber sleeve is divided into normal temperature and high temperature. Its sealing performance is the key to ensure the success of the packer. The research on the expansion agent used in the source of the driving force is very meaningful for the high temperature packer rubber sleeve. Therefore, it is very necessary to select the corresponding parameters of the packer rubber cylinder and to perform indoor inspection before the packer goes downhole.
