摘要 在广泛调研国内外相关文献的基础上,利用地震资料最新重处理和解释成果,结合最新收集的国外地质研究资料,系统总结分析了北康盆地构造演化特征、沉积特征、油气地质条件。研究认为盆地总体上经历了断陷期、坳陷期和区域沉降期三大构造演化阶段,主要发育三角洲相、滨浅海相、半深海—深海相,局部古隆起地区发育碳酸盐台地。北康盆地普遍发育中始新统、上始新统—下渐新统和上渐新统—下中新统3套烃源岩;油气储层主要有古近系砂岩、中中新统石灰岩/礁灰岩两大类;上新统—第四系泥质岩层为区域性盖层。北康盆地油气资源潜力巨大,石油地质资源量为8.86×10~8t,天然气地质资源量为14855×10~8m^3。 Based on the extensive investigation of related literatures in China and abroad, the latest seismic data reprocessing and interpretation results, and the latest collections of foreign geological studies, systemic summarization and analysis were completed on the tectonic evolution, sedimentary characteristics, and petroleum geological conditions in the Beikang Basin. The results show that the Beikang Basin generally experienced three tectonic evolution stages, i.e. fault depression, depression and regional subsidence, giving rise to delta facies, littoral neritic facies, and bathyal-abyssal facies, or carbonate platform in local paleo-uplifts. Three sets of source rocks are developed in the Middle Eocene, the Upper Eocene-Lower Oligocene, and the Upper Oligocene--Lower Miocene, respectively. Oil and gas reservoirs have been identified within the Paleogene sandstone and the Middle Miocene limestone/reef limestone. The Pliocene-Quaternary mudstone acts as the regional caprock. In conclusion, the Beikang Basin has huge potentials of oil and gas resources, with geological resources of oil and gas of 8.86× 108t and 14855 × 108m3, respectively.
