摘要
交联酸体系具有良好的温度、剪切稳定性,携砂性能、缓速性能和高粘度、低滤失的作用,可满足储层深度改造的目的。结合狮子沟油田深度酸压技术与狮31井储层特点,应用新型交联酸酸压加砂工艺,提高裂缝沟通深度与酸液作用距离,连通远井断层裂缝系统和储集空间;且裂缝被支撑,不能闭合,形成高导流能力油气渗流通道,达到提高油井产量的目的。由于狮24井区E32层组上部油层动用程度低,该井措施改造与增产效果将为这一构造勘探与开发提供指导作用。
Cross-linked acid system has many good characteristics such as temperature and shearing resistances, sand carrying ability, delayed action, high viscosity and low filtration that can stimulate the farther region from the well bore. Combing deep acid fracturing in Sizigou oil field with reservoir characteristics, cross-linked acid fracturing tech has been used to raise crack communication and influencing distance of acid fluid, link fault crack at far away well and reserve space. that been supported of crack results in much more oil-gas flow channel with much higher conductivity. The experience acquired in the stimulation course of well Shi31 will be a better guide to the exploration and the exploitation of this region.
