摘要

根据钻井资料和地震剖面,分析了江陵凹陷盐构造特征和盐构造形成的动力条件,探讨了江陵凹陷盐构造类型、成因机制及演化。分析表明,江陵凹陷发育盐枕、盐背斜、盐脊三种盐构造类型;将盐构造活动划分为沙市组晚期-新沟嘴组沉积期为盐构造孕育阶段、荆沙期-荆河镇早期为盐构造生长阶段、古近纪末期-新近纪早期盐构造盐构造定型三个阶段;同时总结盐构造的活动对油气聚集成藏的影响。
According to drilling data and seismic profile, salt structure features, dynamic conditions of salt structure formation, its genetic mechanism and evolution have been discussed and analyzed in this paper. The analysis indicates three structural types, salt pillow, salt anticline and salt-apex, have been developed in Jiangling depression, which divides the salt tectonic activities into three stages. The sedimentary period of late Shashi formation-Xingouzui formation is the structural generation stage, the Jinsha period-Jinhezhen early period is he structral growth stage and the late Paleogene-early Neogene period is the structral formation stage. At the same time, the effect of salt structure activities on hydrocarbon accumulation has been summarized.
