研究区延10油层组沉积相特征分析的研究,对该地区油藏开发具有显著意义,通过对各个地层的岩电特征、沉积构造类型研究,可将沉积相分为河道、河道间、河漫等亚相和滞留沉积、心滩、河道砂、河道边缘、泥和薄层砂、河漫滩、河漫沼泽等微相。并采用优势相编图法,绘制研究区延10各小层沉积微相平面分布图和砂体厚度等值线图。从而得出河道砂体厚度较大,且主要发育河道亚相,心滩、河道砂和河道边缘砂为主的沉积微相。
The research on sedimentary facies analysis of Yan10 oil-bearing formation in the study area is of great significance to reservoir development in this area. Based on the research on the lithologic characteristics and sedimentary structure types of various strata, the sedimentary facies can be divided into river channels, river channels, Such subfacies and sediment deposition, heart beach, river sand, river edge, mud and thin sand, floodplain, river Man swamp and other microfacies. And the advantage of the phase diagram method, draw the study area of 10 small sedimentary microfacies plane distribution map and sand body contour map. The result shows that the sedimentary microfacies are mainly composed of thick channel sand bodies, mainly subfacies, heart beaches, channel sand and marginal sand of the channel.
