摘要:
我国目前在碳酸盐岩油气勘探阶段常用的储层分类评价标准已难以满足溶蚀孔洞缝广泛存在及构造裂缝发育的古岩溶储层评价的实际需要。选择塔中西部上奥陶统良里塔格组古岩溶储层, 在系统分析储层特征的基础上, 通过表征残余岩溶和开展构造裂缝预测, 引入残余岩溶强度(R)和岩体破坏接近度系数(η)2个参数, 作为古岩溶储层评价的重要定量指标;并与多项储层地质参数综合, 进一步完善了碳酸盐岩古岩溶储层的分类评价标准, 并用于对该地区良里塔格组叠加型古岩溶储层的评价预测。将本区良里塔格组古岩溶储层划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ4类, 并应用多因素综合分析叠合成图法在平面上进行储层评价预测, 认为Ⅰ、Ⅱ类储层主要分布于S2井TZ45井TZ12井一带和 Z11井TZ10井TZ11井一带。
