| 摘 要： | 川中南部地区下二叠统栖霞组在钻探中发现栖二段细—中晶白云岩是良好的储层,并且多口井获得工业气流,展示出一定勘探潜力。为进一步预测川中南部地区白云岩的储层分布特征,加快研究区下一步勘探开发,应用储层岩性特征识别、碳氧同位素、包裹体测温、阴极发光以及稀土元素分析研究白云岩储层成因,结果表明栖霞组白云岩无石膏或其他蒸发盐岩伴生,储集岩以细—中晶白云岩和灰质白云岩为主,主要分布于栖二段;栖霞组白云岩C、O同位素测试δ~(13)C为4.03‰~4.77‰、古盐度为131.74~133.39,包裹体均一温度为110~180℃,阴极发光较弱,基质白云岩发紫红色光,溶洞充填马鞍状白云岩不发光;稀土元素的轻稀土和重稀土分布趋势一致,保持了原岩的稀土配分趋势;综合分析认为栖二段白云岩为埋藏成因,其中裂缝和溶洞充填的马鞍状白云岩为热液成因。
