| 摘 要： | 酸化压裂是碳酸盐岩油气藏提高单井产量的常用增产工艺措施之一。酸压裂缝的长度和导流能力则是评价酸化压裂施工有效性的两个主要指标。复杂岩性储层的酸压反应机理、酸压工艺方法不同于常规碳酸盐岩储层，而目前国内外对于复杂岩性储层岩石导流能力认识较少。针对玉门青西油田复杂岩性储层，开展了一系列的室内酸蚀导流能力的实验研究，获得了一些重要结论。实验结果不仅指导了油田生产，而且提高了人们对复杂岩性油气藏增产机理的认识。

| Abstract: | Acid fracturing is one of the conventional and the effective method to stimulate in carbonate formations.The effectiveness of acid fracturing is generally evaluated by the efficient length of fracture and the residual conductivity.The kinetic mechanism of the rock with acid and the fracturing methods of complex lithology,on which people have little knowledge,have much different from common carbonate formations.This paper presents lots of the research results of the complex lithology from Yumen Qingxi oilfield on etched-fracture conductivity.The research not only gives us some light on the complex lithology stimulation,but can extend to production in practice. |
