drill core

According to characteristics of carbonate reservoir and primary matrix leakoff experimental model,We has established three leakoff models,such as broken core leakoff model,bored core leakoff model,and parallel plate core leakoff model,and determined each using range and object.

根据碳酸盐岩储层的特点 ,初步建立了三种滤失模型 ,在原有基质滤失实验模型基础上 ,新建立了岩心破开滤失实验模型、岩心钻孔滤失实验模型及平行板岩样滤失实验模型 ,并确定了各自的适用范围及对象 ,提高了室内实验模拟作业真实情况的程度 ,形成了较为规范的酸液滤失室内评价技术 ,对推动碳酸盐岩储层控制酸液滤失技术的发展具有重要意义。
