摘要
随着盆地模拟和地质建模技术的不断进步,油气成藏研究逐渐向定量化、动态化和3D可视化方向发展。通过集成PetroMod多维度盆地模拟和Petrel数据处理的功能,搭建起多维度、动态化、可视化技术平台,建立了勘探阶段空间地质建模技术的流程及方法,包括构造建模、岩相建模、参数设置和模型校正。应用该技术,首次建立了琼东南盆地宝岛凹陷空间地质模型,重点实现了深水区南部断阶带油气成藏动态化和成藏3D可视化,恢复了4个关键时期的空间成藏动态过程,研究表明,南部断阶带早期成藏时空配置良好,成藏规模小,晚期成藏时空配置优越且纵向叠置,成藏规模大。南部断阶带成藏模式为煤系和浅海源岩供烃、断裂-砂体-构造脊阶梯型输导、大型海底扇储集、多层系复式聚集,主力聚集层系是陵三段和三亚一段,下一步勘探应积极寻找多期叠置成藏的大型储集体。
        With the technology development of basin simulation and geologic modeling,the study of hydrocarbon accumulation goes in quantitative,dynamic and 3 D-visual direction.Combined with multi-dimension simulation of PetroMod software and data management of Petrel software,a technology platform called"multi-dimension,dynamic and visual"was constructed,and the technological process of spacial geologic modeling for exploration was built,which consisted of structure modeling,lithofacies modeling,parameter setting and model correction.By the former technology,the spacial geologic model of Baodao Sag in Qiongdongnan Basin was built in first time,while the dynamic and 3 D-visual accumulation of southern fault terrace zone in deepwater was realized;finally,the spacial and dynamic accumulation process of southern fault terrace zone was restored on 4 critical periods.In conclusion,the earlier spatiotemporal relation was fine with smaller accumulation scale in southern fault terrace zone,and the later spatiotemporal relation was excellent with larger accumulation scale.In conclusion,the accumulation pattern in southern fault terrace zone could be described as hydrocarbon supplied by coal and neritic source rocks,migrated with faults,sand and ridges in stair shape,accumulated in large submarine fans,also compositely in multilayers,the 3 rd Lingshui member and the 1 st Sanya member should be selected as the major layers,and the next exploration target will be the large reservoirs accumulated in multi-periods and multi-layers.
