对砂岩储层实施酸化压裂技术,存在诸多影响成效的因素,本文详细分析了在油田深井的砂岩储层采取酸化压裂工艺的条件以及具体的技术要点,认为对砂岩储层中裂缝天然发育、地应力高油井、注水井及气井等改造效果显著,分析其原理,概括性地阐述了应用砂岩储层酸压的工艺与酸液体系的工艺办法,同时配上在砂岩储层酸压的现场应用实例,并归纳出相关应用结论。
There are many factors influencing the effectiveness of acid fracturing in sandstone reservoirs. In this paper, the conditions of acid fracturing in sandstone reservoirs of oilfields and the technical points are analyzed in detail. It is considered that the natural development of fractures in sandstone reservoirs, , High geostress wells, injection wells and gas wells and other transformation effect is significant, analysis of its principles, a general description of the application of sandstone acid pressure process and acid system process, coupled with acid pressure in the sandstone reservoir Field application examples, and concluded the relevant application conclusions.
