Description: Well casing through regulation is within the thin-walled tubular tool to detect casing bore size. I pass by the original well regulated with a bypass circulation channels, in addition to the circulation through the well annulus regulation between outer and inner diameter of the sleeve, you can also pass the annulus between the well from the cited regulation shoes the formation of a new cycle path, which through well regulated only with our company to carry out the new MFC-one through the integration of operations work well scraper hydraulic scraper mate job. Because MFC hydraulic scraper blade is in the recovery state, do not go down the path scraper scraping process, so that the situation does not appear clogged wells through regulation, but when the whole process is completed through the well proven casing situation, pressure from the wellhead by pitching the blade open, from the string while you can achieve scraper operations, scraped solids are circulating through the mud back to the wellhead. Solved through conventional wells regulatory and conventional scraper can not perform the job through scraping one problem. Thereby reducing the time from the drilling operations, effectively improve the operating efficiency and reduce operating costs.
How it works: At the end of normal operations through wells, are circulating rinse well bore until the lower back all the mud from the well after pitching can be opened from the wellhead pressure - scraper scraper blades, blade fully open after guarantee continued pressure switch open sleeve loop holes, you can reverse circulation flushing.
You can rotate, decentralization, put on the string operation scraper operations, this time due to the circulation hole has been opened, when put on the operating string scraping the wall, the liquid column does not return within a rig, thus ensuring the safety of civilized production. After scraping the walls were again positive cycle wash well to back out of concrete blocks and other debris cleared.
Pipe string configuration: scraping the wall through the integration work well pipe string structure.
