摘要:
酸压是深层、超深层海相碳酸盐岩油气藏增产的核心技术,而如何在超高温和高闭合应力下保持住酸蚀裂缝导流能力是酸压改造能否成功的关键。利用自研的高温高压酸蚀裂缝导流能力测试装置开展不同酸液及组合下灯影组岩样裂缝导流能力实验,使用三维激光扫描仪获取酸刻蚀裂缝形貌,基于此,采用Airy(艾里)应力函数和复变量法,描述酸蚀裂缝闭合程度,结合局部立方定律,耦合酸压模型,形成了酸蚀裂缝导流能力数值计算方法。结果表明:与低闭合应力(5 MPa)相比,高闭合应力(90 MPa)下多数酸液及其组合的导流能力降低了一个数量级;闭合应力增加,不同酸液及组合的导流能力降低模式有较大区别,可能会出现2次快速下降阶段;不同酸液组合注入可在一定程度上改善超高温和高闭合应力下酸蚀裂缝导流能力;酸蚀裂缝导流能力计算模型与实验结果平均误差较小,约10.6%,且能表征缝内各处导流能力分布及大小;相同工程参数条件下,四川盆地灯影组四段酸压裂缝导流能力较灯影组二段更高,可为四川盆地深层、超深层海相碳酸盐岩酸压改造方案优化设计提供理论指导。
