摘要

较之长兴组、飞仙关组一、二段而言,川东北飞仙关组飞三段鲕滩储层发育的整体格局不清楚,制约了飞仙关组飞三段的油气勘探。为此,结合区域沉积演化分析,通过河坝地区单井层序划分对比,将飞仙关组飞三段下部鲕滩储层分为5个高频旋回,通过储层地震响应特征分析和属性提取,指出了不同期次储层发育的有利区。结果表明鲕滩储层由早到晚有逐渐向东迁移的趋势,并且不同期次鲕滩储层的发育受沉积古地貌高的控制。
An integral pattern on oolitic-shoal reservoir of Feixianguan 3 Member,northeastern Sichuan Basin,is not well known so far,resulted in a slow exploration speed.In this study,the oolitic-shoal reservoir of lower Feixianguan 3 Member in Heba area can be classified into 5 high-frequency cycles by sequence classification and correlation.In addition,some favorable plays are presented for different reservoir-developed stages by both analysis on seismic response feature and attribute acquisition.Results show that:(1) this kind of reservoir appears a trend of gradual east-ward migration from early to late;and (2) the development of oolitic-shoal reservoir in different stages might be controlled by pa leogeomorphy.
