泌阳凹陷安棚深层系成岩作用与成岩阶段划分

为了对泌阳凹陷安棚深层系的成岩作用与成岩阶段划分有一个明确的认识 ,以储层类型及其岩石学特征、沉积相研究为基础 ,将该区的成岩作用划分为机械压实作用、胶结作用及溶蚀作用 ,建立了成岩作用序列 ;将成岩阶段划分为 4个期 5个亚期 ,安棚深层系主要为晚成岩 A3 亚期及晚成岩B期 ;最后对安棚深层系核三段 - 砂组及大仓房组上部的成岩作用和阶段划分进行了归纳 .本文的研究对安棚深层系寻找有利储集带具有一定指导意义

Diageneses and division of diagenetic stage of deep strata series in Anpeng area,Biyang Sag

Based on the studies of the type, lithologic feature and sedimentary facies of the reservoirs of the deep strata series, it is held that the diagenesis of the reservoirs includes compaction, cementation and corrosion, the sequence of diagenesis is established. Diagenetic stage is divided into 4 stages and 5 substages. The deep strata series in Anpeng area belongs to mainly A 3 substages and B stage of late diagenesis. At last, the diageneses and the division of diagenetic stage of the deep strata series in the lower of 3 member of Hetaoyuan formation and the upper of Dacangfang formation are summed up. The result of the study in this paper is of significance to finding favorable oil and gas reservoir zones in Anpeng deep series.
