APPLICATION
Spear -type scratchers “SP-Tekhno” are used for initial punching through asphaltene, resin, and paraffin plugs built up inside of the tubing string. For subsequent regular cleaning jobs, bladed scrapers “SL-Tekhno” and milling scrapers “SF-Tekhno” are used in combination with automatic 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 end is a replaceable element, 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 that can result 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.
