Abstract

The invention relates to a packer performance test testing device, and belongs to the field of oil-gas well downhole work tools. The packer performance test testing device is composed of an oil storage tank, a testing box and a hydraulic cylinder, wherein an oil inlet pipe is arranged at the bottom of the oil storage tank, an oil return pipe is arranged at the top of the oil storage tank, the testing box is arranged at one side of the oil storage tank, the oil storage tank is communicated with the testing box through the oil inlet pipe and the oil return pipe, clamping bases are symmetrically installed in the testing box, the hydraulic cylinder is installed at one end of the testing box, and a piston rod of the hydraulic cylinder extends into the testing box. The packer performance test testing device is simple in structure and convenient to operate, and assembly and disassembly of the packer performance test testing device and a packer are convenient; the packer performance test testing device is high in universality, conventional packers can be tested, and other accessory downhole tools can be sufficiently verified at the same time.

Description

technical field [0001] The invention relates to a packer performance test device, which belongs to the field of downhole operation tools for oil and gas wells. Background technique [0002] The packer is one of the important downhole tools in the oil field drilling and production process. The performance of the packer affects the operation effect of fracturing, oil testing, layered water injection and other processes. The failure of the packer will increase the construction period and construction cost. etc. Therefore, the performance test of the packer is an important technical link. [0003] Due to the complex environment at the bottom of the well during actual construction, the length of the pipe string will be deformed due to temperature effects or pressure effects, resulting in axial tensile or compressive loads acting on the packer. In order to make the function of the packer meet the requirements of the use environment and actual construction, during the development ...
