通过对白垩系石油地质条件的系统分析和勘探实践的思考,认为白垩系具有多层系烃源岩供给和良好储盖组合的成藏特点,油藏类型以构造和构造-岩性油气藏为主,有利的沉积相带和局部构造控制油气分布,侧向运移聚集成藏为主,具备好的成藏条件,存在有大的勘探潜力,白垩系资源总量2928×104t。并提出了实行规模化勘探策略,动态分析、综合研究,多技术应用,以实现油气突破和新油田发现。
Based on the systematic analysis and exploration practice of the petroleum geological conditions in the Cretaceous, it is considered that the Cretaceous has the reservoir forming characteristics of multi-layer source rock supply and good reservoir-cap assemblage. The reservoir types are characterized by structural and tectonic-lithologic reservoirs The main and favorable sedimentary facies belts and local structures control the distribution of oil and gas, mainly lateral migration and accumulation, with good reservoir forming conditions and great exploration potential. The total Cretaceous resources are 2928 × 104t. And proposed the implementation of large-scale exploration strategy, dynamic analysis, comprehensive research, multi-technology applications in order to achieve oil and gas breakthroughs and new oil field discovery.
