APPLICATION
Milling scrapers “SF-Tekhno” are designed for dewaxing/ removal asphaltene, resin, and paraffin deposits from tubing ID in high rate wells. Rotation of cutting head created by a substantial flow, i.e. over 30 cubic meters per day, effectively ensures cutting paraffin layer from tubing internal surface.
Effective cleaning is achieved through regularity of tubing cleaning using automatic well dewaxing unit “UDS-Tekhno 101” or semiautomatic slickline winch “LKI-Tekhno”.
Scrapers made by LLC NPF “TehSmart” have similar design as other scrapers such as dynamic scraper “SD”, expandable scraper, Bolotov’s scraper, PUR.55, TU.55, PU.55, DI.55, KI.55, PA.55, KP.55, PL.55, SR-73, SL-73, Stroev's scraper.
Scrapers by LLC NPF “TehSmart” are suitable for use with well dewaxing units of the following types: UDS, UDS-Tekhno, UDS-3000T, UDS-1M, UOK-NKT, PADUS, PADU-3M, DSA-18, MDS-010, Suleymanov’s winch.
To ensure effective wax removal, wellbore and fluid condition should be considered when selecting scraper elements for a cleaning job. Cutting ends are replaceable elements, and can be changed upon prior agreement with Client. Diameter of cutters, weights size and mass, scraper configuration can be agreed on prior to a cleaning job. Lead weight while preserving smaller size provides for larger mass for a more effective operation result.
A mandatory element is a swivel joint in order to prevent twisting of wire followed by kinks formation resulting in a potential job failure on a wellsite.
To prevent damage of tubing with internal polymer coating, heavy duty plastic mills are used in a scraper. They keep the internal coating of the tubing intact.
