Description

Anti-blocking pipe cleaning tool

Technical Field

The utility model belongs to the technical field of pipeline cleaning, and particularly relates to an anti-blocking pipe cleaning tool.

Background

In the process of gathering and transporting oil and gas pipelines, because of reasons such as ambient temperature and pressure change, the heavy component fluid substance or oil gas carried out from the stratum has partial residual heavy component substance in the oil and gas pipe transportation process after preliminary treatment, the heavy component substance can produce deposit and the absorption on the pipeline inner wall in the pipeline, cause the pipeline circulation passageway undergauge because of continuous deposit and adsorption process, lead to the defeated pressure of pipe to rise unusually, the back pressure increases, transportation pressure consequently and increase, influence oil and gas well output, increase stratum energy consumption, cause serious potential safety hazard to the defeated production of oil and gas gathering, therefore, need the pig to dredge the natural gas pipeline.

The natural gas pipeline cleaning device has various types, including a rubber ball, a resin leather cup, a mandrel pipe cleaning device, a water soluble pipe cleaning device and the like. However, the cleaning process of the spherical pig is only a small contact surface effect, and the cleaning effect is not ideal. The mandrel pipe cleaner has troublesome operation, and the bent part (turning) is easy to block due to larger resistance; the water soluble pipe cleaner is made of pure water soluble material, can be dissolved when meeting water, and has the characteristic of dissolving when meeting water and generates abrasion on the sealing surface of the pipe cleaner when passing through a welding line and residues connected by the pipeline in the long-distance pipeline conveying process, so that the sealing performance of the pipe cleaner is greatly reduced, and the pipe cleaning effect cannot be achieved.

Therefore, the problem that the cleaning effect is poor and the blocking problem often occurs in the pipe cleaner in the prior art, when the blocking problem occurs, the pressure behind the pipe cleaner needs to be increased to force the pipe cleaner to pass through the blocked place, so that the pipeline pressure is increased abnormally, if the blocking condition of the pipe cleaner is serious, the production of the pipe cleaner and the surrounding natural gas is stopped and emptied, the blocked pipe section is cut off and taken out of the pipe cleaner, and thus the overall production benefit of an enterprise is reduced and the production safety risk is increased; if the pig damages and stops the operation, need to send a pig again and push out damaged pig, can cause manufacturing cost to increase.
