摘要
本文主要应用岩石学理论 ,对雪 1井三叠系雷口坡组、嘉陵江组储集层段的沉积、成岩作用进行综合研究。探讨了雪 1井三叠系雷口坡组、嘉陵江组储集层段的沉积模式 ,划出了有利的沉积相带 (滩亚相 )。认为三叠系雷口坡组、嘉陵江组储层气藏的形成主要受控于沉积和成岩作用 ,储层主要发育于滩亚相发育部位 ,滩亚相沉积物必须配之与有利的成岩作用及成岩演化序列 ,才有可能发育成有利储层。
By applying the petrologic theory, the sedimentation and diagenesis of reservoir layers and sectors in Leikoupo group and Jalingjiang group of Xue-1 well of Triassic are studied in the paper synthetically. The sediment mode of reservoir layers and sectors in Leikoupo group and Jalingjiang group of Triassic system of Xue-1 well is researched, the effective deposition_facing belts (sub_beach facing) is drawn. It is thought that the formation of reservoir gas pool of Leikoupo group and Jalingjiang group is mostly controlled by deposition and diagenesis, and the reservoir mostly is developed in development of sub_beach facing. The sub_beach facing sedimentation may turn into well reservoir with advantageous diagenesis evolution sequence.
