Abstract:

随着震旦系—下寒武统天然气勘探取得重大发现,对古构造格局有了新的认识,该地质时期发育呈南北向展布的隆坳构造。桐湾期、加里东期、印支期为四川盆地3期关键构造变革期,其不整合分析是构造演化研究的重要手段,因此有必要通过关键构造变革期不整合研究,分析构造变革对古构造演化的影响。基于钻井、野外露头、地震资料分析,并结合区域地质资料,探讨关键构造变革期不整合发育特征,研究震旦纪—早寒武世古构造演化及其对震旦系天然气成藏的影响。结果表明1)3期关键构造变革形成了震旦系—下寒武统(桐湾期)、中上寒武统—二叠系(加里东期)及上三叠统—侏罗系(印支期),7个区域性不整合;2)不整合具有叠合性、迁移性特征,叠合性主要反映构造继承性,迁移性主要反映古构造的变迁过程,依据不整合发育特征,高石梯-磨溪构造区构造演化划分为发育期、调整期及稳定期3个演化阶段;3)不整合与隆起区丘滩体叠加控制了震旦系岩溶储层发育,不整合面可作为油气运聚优势通道,不整合迁移性有助于分析古构造圈闭的形成与消亡。分析认为,关键构造变革期不整合特征分析对认识震旦纪—早寒武世隆坳构造后期演化及油气运聚具有重要意义。
