油气藏酸压工艺技术现状与发展

酸压是油气藏增产、注水井增注的重要措施,在油气田开采中得到了广泛运用。酸压效果的成败取决于对地层因素的认识和合理的选择酸液体系及酸压工艺。介绍了目前国内外所应用的酸液体系类型及酸压工艺技术,对各种酸压工艺方法、原理、特点及适合酸压的地层因素进行了分析,总结了目前酸压的经验和存在的问题。酸压将会在水平井,复杂砂岩储层的改造工艺中得到普及。建议在以后的工作中加大针对不同物性的储层进行酸液、工艺的优选研究,以达到最佳的改造效果。

Present situation and development of oil and gas reservoir acid fracturing technology

Acid fracturing is the major measure to improve the production of oil and gas reservoirs and water injection well stimulation, which has been widely used in oil and gas field exploitation. The acid fracturing effect depends on the knowledge of formation factors, selection of reasonable acidizing fluid system and acid fracturing technology. Various acidizing fluid systems and acid fracturing technologies applied in the world are introduced in this article. The paper analyzes the different acid fracturing met...
