摘要

摘要: 莺歌海盆地属南海北部被动大陆边缘新生代异常高温高压盆地,其异常高温高压地层系统主要展布于盆地中部莺歌海坳陷区泥底辟构造带,因此,泥底辟热流体上侵活动,尤其是上新世后期的热流体活动与异常高压区带的展布,控制了天然气及CO₂的运聚富集特征。根据所获大量地质地球化学、地球物理资料及近年来天然气勘探成果,重点对盆地异常高温高压特征、高温高压环境下天然气成藏主控因素及运聚规律等进行了综合剖析与探讨,以期对该区进一步天然气勘探及研究有所裨益。

Abstract: Yinggehai basin developed in the Cenozoic is an abnormal high geotemperature and superpressure basin that belongs to the passive continental margin in the north of the South China Sea. The high geotemperature and superpressure system is mainly located in the diapir belt of the Yinggehai depression in the middle of the basin, so the intrusion of heat flow in the diapir belt, especially the movement of heat fluids of the late Pliocene and the distribution of abnormal high geotemperature and superpressure control the migration-accumulation of gas and CO₂.Based on close relationships between the distribution of abnormal high geotemperature and superpressure in the basin and the characteristics of migration-accumulation of gas, we can analyse and predict the regulation of migration-accumulation of gas so as to provide a decision-making for gas exploration plan.
