Abstract

The invention discloses a device and a method for testing anchoring and sealing performance of a pipeline plugging device. The device comprises a simulation pipeline and a simulation plugging device, wherein the simulation pipeline is a test bench used for simulating an oil and gas pipeline, one end of the simulation pipeline is closed and is used for injecting a pressurized liquid medium, and the other end of the simulation pipeline is in an open state; the simulation plugging device is arranged in the pipeline, the simulation plugging device is provided with a central shaft, sliding teeth and glue seals, the sliding teeth and the glue seals are arranged in the circumferential direction of the central shaft and are in clearance fit with the inner wall of the pipeline, and after axial force is applied to the central shaft, the sliding teeth move outwards in the radial direction and form anchoring on the inner wall of the pipeline; and a glue seal is pressed under the action of axial force and expands in the radial direction to seal the pipeline. The key performance of the designed plugging device can be effectively verified, that is, the sealing performance of glue sealing and the anchoring performance of radial sliding teeth are effectively verified.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline plugging, in particular to an anchoring and sealing performance testing device and testing method for a pipeline plugging device. Background technique [0002] Pipeline transportation has unique advantages such as less one-time investment, low transportation cost, high safety, and environmental protection. It is especially suitable for long-distance transportation of flammable and explosive oil and gas. With the wide application of these pipelines in natural gas transportation and the increase of service life, the requirements for pipeline maintenance and repair technology are getting higher and higher. [0003] At present, the hanging occluder, also known as the disc occluder, is widely used in the non-stop sealing operation. The premise of using the hanging occluder is that a pipe with the same diameter as the inner diameter of the pipe must be opened. holes, so that the strength o...
