资阳地区灯影组储层段为一套受波浪作用为主的浅水台坪白云岩沉积,由17种岩石微相和5种相序组成的地层中米级——亚米级沉积旋回明显。其储层段由三个不完整的层序构成,高水位体系域沉积构成了层序的主体,层序界面为I型和Ⅱ型。沉积和层序特征受到海平面变化、构造沉降和碳酸盐沉积速度的共同控制。
The Dengying Formation reservoir zone in Ziyang is a wave-dominated shallow-water daping dolomite sedimentary. The Mi-level-sub-grade sedimentary cycle in the strata composed of 17 kinds of rock microfacies and five kinds of phase sequences is obvious. The reservoir section is composed of three incomplete sequences. The sediments of high-level system tract constitute the main body of the sequence, and the sequence interfaces are Type I and Type II. Sediment and sequence features are jointly controlled by sea level changes, tectonic subsidence and carbonate deposition rate.
