Structural features and preservation evaluation of shale gas reservoirs in the Fuling area, Sichuan Basin

  • 摘要: 四川盆地涪陵页岩气田五峰组-龙马溪组含有丰富的页岩气资源,但该区经历了多期构造叠加作用,对页岩气保存条件造成了重要影响。系统研究了涪陵地区的构造特征和保存条件。该区发育北东向、北西向2组构造体系,主要形成于晚燕山期,受3套滑脱层系影响,纵向上变形特征存在差异性,可划分出3个构造形变层,中构造层变形相对强烈。将构造样式、断裂规模、剥蚀程度、裂缝密度作为构造变形的主要评价指标,可将涪陵地区平面上按构造变形分为东、西2带,西带构造变形较弱,保存条件较好。为进一步落实页岩气开发有利区,在"东西分带"认识的基础上,通过构造变形定量表征和地震预测,建立了一种涪陵地区保存条件量化评价方法。根据评价结果,在西带优选出3个有利目标区,在东带优选出2个有利目标区。
