Bag descaling pipe cleaner

Abstract

The invention belongs to the field of pipeline descaling devices, and in particular relates to a cloth bag descaling pig, including a bag type pipe pig, a spring skeleton type pipe pig, an umbrella resistance plug and a pull rope. The spring skeleton type pipe pig is located in the bag Between the bag-type pipe pig and the umbrella-type resistance plug, the bag-type pipe-cleaner and the umbrella-type resistance plug are connected by a pull rope; Installed on the surface of the elastic cloth bag, the scraping nails are arranged in an axial line on the surface of the elastic cloth bag, the coil spring is located inside the elastic cloth bag, and the coil spring is wound at least one on the scraping nail when passing through each scraping nail ring, so that the scraping nail is fixed by the coil spring, the elastic filler is filled in the elastic cloth bag, and the two ends of the elastic cloth bag are sealed; compared with the prior art, the jet water pressure required by the present invention is smaller, and one Clean the dirt inside the pipe to avoid the temperature loss of the jet water.

Description

technical field [0001] The invention belongs to the field of pipeline descaling devices, in particular to a cloth bag descaling pipe pig. Background technique [0002] Oilfield pipelines that have been used for a long time have serious fouling. If they are not cleaned and descaled, production efficiency will be affected. At present, the methods of cleaning oilfield pipelines mainly include physical cleaning and chemical cleaning. Among them, the chemical corrosion of the pipeline is serious, which reduces the service life of the pipeline. There are two physical methods, one of which is the cavitation jet, which has a better descaling effect, but the water pressure required by the cavitation jet is relatively high, and there are certain safety hazards in high-pressure operation; the other is to use the jet to add Scaling is carried out by scraping the pipe cleaner, but the diameter of the pipe cleaner is fixed, and it is easy to get stuck in the pipeline, and when the fouli...

There are two physical methods, one of which is the cavitation jet, which has a better descaling effect, but the water pressure required by the cavitation jet is relatively high, and there are certain safety hazards in high-pressure operation; the other is to use the jet to add Scaling is carried out by scraping the pipe cleaner, but the diameter of the pipe cleaner is fixed, and it is easy to get stuck in the pipeline, and when the fouling is serious, the jet also needs a lot of water pressure to push the pig forward, which is different from the air. Acupoint jets have the same safety hazards
