俄罗斯针对阿尔兰油田的构造严重非均质、低渗透和原油高粘度的碳酸盐岩油藏 ,用常规酸处理效果不断下降的情况 ,研制成功了一种SNPX(DN)— 90 10盐酸酸化液 ,并已成功地将其用于阿尔兰石油公司的碳酸盐岩地层油井的增产处理 ,见到了明显的增油效果。
Russia developed a SNPX (DN) - 90 10 Hydrochloric Acid Acidification for serious structural heterogeneity, low permeability and crude oil high viscosity carbonate reservoirs in the Arland Oilfield under the conditions of conventional acid treatment. Liquid and has successfully been used to ramp up production wells in Allan Oilfield’s carbonate formations to see significant oil enhancement.
