METHOD OF TREATMENT OF BOTTOM-HOLE ZONES OF WELLS PRODUCING HEAVY OILS AND NATIVE BITUMENS Russian patent published in 2002 - IPC

Abstract RU 2178070 C2

FIELD: oil producing industry, particularly, methods of treatment of bottom-hole zones of producing wells with reduced production rate of heavy oils or native bitumens due to deposition of asphaltene-resinous-paraffin materials. SUBSTANCE: hydrocarbon fluid for treatment of bottom-hole zone is used in the form of fraction of alpha-olefins with carbon molecular formula C6-C20 and temperature of fractional distillation of 70-300 C. Said fluid is injected into formation, forced in it and left to stand in bottom-hole zone. Then, products of dissolving are removed. EFFECT: higher efficiency of treatment and higher production rate of wells. 1 tbl, 1 ex
