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 DEG C.

(ZH)

本发明涉及特别在至少100℃的温度下烷基磺酸、尤其是甲磺酸在提高地下含石油的和/或含有气体的碳酸盐岩层的渗透性以及在溶解石油生产期间的碳酸盐杂质和/或含有碳酸盐的杂质中的用途。
