摘要:
利用物性数据分析、铸体薄片鉴定、扫描电镜观察、图像分析技术等手段,探讨了临南洼陷沙三段砂岩储层孔隙度控制因素,并运用灰色关联等研究方法量化各因素的影响程度,最终建立储层孔隙度综合预测模型。结果表明,控制临南洼陷沙三段砂岩储层孔隙度的因素包括与沉积相关的粒度因素和分选因素,以及与成岩相关的压实因素、胶结因素和溶蚀因素。在限定压实条件下,孔隙随埋深的变化和岩石粒度、分选系数具相关性;粒度较粗的储集层物性相对较好,且分选性对原始物性的影响要大于粒级的影响;碳酸盐岩胶结物质体积分数大于5%时,孔隙度与碳酸盐岩体积分数呈负相关;以长石颗粒溶蚀为主的溶蚀作用具有明显的增孔效应;随着黏土矿物含量增高,孔隙度逐渐降低。运用灰色关联法量化各项地质参数对储层孔隙度的影响,进而在设定现今储层孔隙度为正常埋藏压实保存孔隙度与其他成岩作用对孔隙度贡献的叠加的前提下,建立了孔隙度综合预测的数学模型。经17组数据的验证,该预测方法的准确率可达90.5%。
