| 摘 要： | 常规加砂压裂过程中往往会给储层和支撑裂缝带来伤害,导致压裂效果有限,甚至无效.为了改善压裂增产效果,提出了酸化加砂压裂复合增产技术,加砂压裂效果显著改善.以长庆油田为例,系统分析了压裂过程中的主要伤害因素,深入剖析了酸液在改善压裂效果方面的作用机理.研究成果为指导和优化施工设计提供了理论依据和技术支持,对类似油田的增产改造具有重要的借鉴意义.

| Abstract: | The damage of reservoir and fracture often happens during conventional sand fracturing,which leads to a poor postfracture response and even invalid fracturing. Comprehensive stimulation technology of sand-adding acid fracturing is put forward in order to improve the stimulation effect of fracturing. This paper analyzes the main damage factors during fracturing,and dissects the mechanism of acidizing fluid in improving postfracture response,taking Changqing Oilfield as an example. The research results provid... |
