摘要 根据沉积特征、孔隙类型及孔隙充填物的地球化学特征认识到川东北地区飞仙关组储层中有2期埋藏溶蚀作用:第一期埋藏溶蚀作用与上二叠统海槽相烃源岩成熟产生的有机酸有关;第二期埋藏溶蚀作用与热化学硫酸盐还原反应产生的H2S有关。两期埋藏溶蚀作用主要发生在台地边缘鲕粒滩相中,台地内泻湖及点滩相中溶蚀作用则相对较弱。分析认为:台地边缘成为天然气勘探的有利地区,台地内为欠有利地区。 Based on the depositional features, pore types, and geochemical behaviors of pore filler, two stages of burial dissolution are identified in the Feixianguan Formation reservoirs in Northeast Sichuan Basin. The first stage was related with the organic acid generated by the mature Upper Permian source rocks of trough facies, while the second stage was related with the H_2S generated from thermochemical sulfate reduction reaction. The dissolution mainly occurred in the oolitic beach facies at platform margin, while it was weak in the lagoon and point bar facies in platform interior. Analysis shows that the platform margin is favorable for gas exploration, in contrast to the unfavorable platform interior.
