(RU) ПРИМЕНЕНИЕ ВОДОРАСТВОРИМЫХ АЛКАНСУЛЬФОКИСЛОТ ДЛЯ ПОВЫШЕНИЯ ПРОНИЦАЕМОСТИ ПОДЗЕМНЫХ, КАРБОНАТНЫХ НЕФТЕ- И/ИЛИ ГАЗОНОСНЫХ ПОРОДНЫХ ФОРМАЦИЙ И ДЛЯ РАСТВОРЕНИЯ КАРБОНАТНЫХ И/ИЛИ КАРБОНАТСОДЕРЖАЩИХ ПРИМЕСЕЙ ПРИ НЕФТЕДОБЫЧЕ
Abstract
(EN)

The invention relates to the use of alkane sulfonic acids, in particular methane sulfonic acid for increasing the permeability of underground petroliferous and/or gas-bearing carbonate rock formations and for dissolving carbonate contaminants and/or contaminants containing carbonates during petroleum production, especially at a temperature of at least 100°C.

(RU)

Применение алкансульфокислот, в частности метансульфокислоты, для повышения проницаемости подземных, карбонатных нефте- и/или газоносных породных формаций, а также для растворения карбонатных и/или содержащих карбонат примесей при добыче нефти, в особенности при температуре не меньше 100°С.
