资福寺洼陷位于江陵凹陷东南部,在晚侏罗-早白垩世基底形成之后经历了晚白垩-始新世新沟嘴组、始新世荆沙组-渐新世荆河镇组和新近纪-第四纪3期构造演化阶段,洼陷总体上表现为NW向的“凹-隆”相间构造格局.古近系盐湖沉积体系发育有沙市组上段和新沟嘴组下段烃源岩,新沟嘴组下段Ⅱ油组烃源岩具有较高的生烃潜力,Ⅰ类生烃区主要分布在洼陷中心;发育了新沟嘴组下段自生自储的原生油藏储盖组合和新沟嘴组下段-荆沙组下生上储的次生油藏储盖组合.原油以来源于本地区的烃源岩为主,断裂和三角洲砂体成为油气运移的主要通道,位于主要生烃区域两侧的构造带为油气运移的主要指向,形成了新沟嘴组自源式成藏模式和荆沙-潜江组异源成藏模式.洼陷北部的荆州背斜带西部为勘探潜力较大的Ⅰ级勘探区,荆州背斜带东部和洼陷以西为Ⅱ类勘探区.“,”The Zifusi Sag,located in the southeast of the Jiangling Depression,has experienced three phases of tectonic evolution since the basement formed,i.e.the first phase from Late Jurassic to Eocene when Xingouzui Formation deposited,the second phase from the Eocene Jingsha Formation to the Oligocene Jinghezhen Formation,and the third phase from Neogene to Quaternary.The sag is characterized by the alternation of uplifts and depressions in a northwest direction.Source rocks are found in the Paleogene brine lake ...
