一种兼具洗油作用的自生酸诱导增粘调控体系及制备方法 技术领域
本发明属于油田化学领域，具体地，涉及一种用于中低温油藏的兼具洗油作用的自生酸诱导增粘调控体系及制备方法。
技术背景
我国是世界上注水开发油田比例较高的国家之一，水驱开发储量占总储量的70％以上。但油田的长期注水开发，导致地层的非均质性加剧，水驱波及不均进一步演变成大孔道窜流，导致注入水沿高渗层向油井突进，油井产出水过多，逐步进入高含水期，势必造成采收率过低。但高含水期开发阶段的油田仍有大量的剩余油未被挖潜，只是由于储层的分异严重，导致储层的动用程度受到限制。因此，高含水期开发阶段的油田仍具备挖潜的潜力。目前提高高含水期开发阶段油田剩余油高效挖潜的措施主要从两个方面开展工作：一个途径是通过向地层中注入调控剂，提高驱油剂的波及系数；另外一个途径是向地层中注入可以改变岩石表面的润湿性和减小毛细管阻力效应的驱油剂，提高驱油剂的洗油效率。CN103980872公开了一种适用于低温油藏的环境友好型冻胶堵剂，该调控剂由两亲聚合物和有机锆组成，能够适用于25～35℃的油藏地层深部调控。该调控剂具有环境友好型的特点，但成胶温度窄，尤其不适于夏季矿场的施工。CN86108877公开了一种锆冻胶堵水调控剂，由聚丙烯酰胺(PAM)或甲叉基聚丙烯酰胺(MPAM)与交联剂无机锆化合物组成。无机锆化合物有氧氯化锆、四氯化锆、硫酸锆、硝酸锆等。该锆冻胶调控剂可满足温度低于70℃油藏堵水，由于锆冻胶体系成胶时间快，现场施工过程中只能采取聚丙烯酰胺(PAM)或甲叉基聚丙烯酰胺(MPAM)溶液与交联剂无机锆化合物交替顺序注入，增加了矿场施工工序，且形成的锆冻胶调控体系成胶迅速，施工过程中存在一定的工程风险。目前研发的储层调控剂主要通过提高驱油剂的波及系数实现原油采收率的提高，较少兼顾储层调控剂本身的洗油效率。CN103254883A公开了一种用于提高高温高盐高硬度油藏原油采收率的驱油剂，由氧化胺型两性表面活性剂和烷基酚聚氧乙烯醚羧酸表面活性剂组成，能够降低油水界面张力达10 -2mN/m。但该 驱油体系适用于相对均质的地层，对于存在渗流优势通道的高含水非均质油藏，注入的驱油剂单独使用时流度不能很好的控制，容易沿高渗层指进，降低了驱油效果。
鉴于中低温油藏常规调控剂无法兼顾洗油效率、单一表面活性剂高含水油藏适应差的难题，需要研发一种新的储层调控体系既能够提高驱油剂的波及体积，同时又能够提高驱油剂的洗油效率，达到长期有效的水驱效果。
发明内容
针对现有技术的不足，本发明提供一种用于中低温油藏的兼具洗油作用的自生酸诱导增粘调控体系及制备方法。该体系初始阶段具有降低油水界面张力提高洗油效率的能力，粘度增加后可实现地层深部调控扩大波及体积的双重作用。
