| 摘 要： | 松辽盆地北部泉三、四段发育3个异常高孔隙带,主要由有机酸溶蚀储层形成。为预测次生孔隙发育带的横向展布,应用成岩作用数值模拟技术,对松辽盆地北部泉三、四段成岩阶段和成岩相的展布进行研究,探讨影响次生孔隙发育的地质因素并对异常高孔隙带进行预测。结果表明:次生孔隙发育的储层主要形成于曲流河、三角洲平原和三角洲前缘砂体,目前处于中成岩阶段A1亚期,发育中期溶蚀成岩相;从盆地边部到中心,早期压实相、早期胶结相、早期溶蚀相、中期溶蚀相、晚期溶蚀相和晚期胶结相呈环带状展布,在纵向上相邻的成岩相,在横向上也相邻,可称之为"成岩相律";泉三段Sq3异常高孔隙带主要分布在中央坳陷周围的边缘地区。 |

| Abstract: | There exist three anomalously high porosity zones vertically in the K1q3 and K1q4 of northern Songliao Basin.The anomalously high porosity zones were formed mainly by dissolution.In order to predict the lateral distribution of secondary porosity zones,the distributions of diagenetic stages and diagenetic facies were studied by numerical modeling,the geofactors affecting the secondary porosity developing were discussed and the anomalously high porosity zones were predicted.The results show that the anomalous... |
