【摘要】 "二次勘探"是针对富油气凹陷提出的一种新的勘探思路和方法,其实质是对富油气凹陷待发现资源分布规律的再认识,核心是整体认识、整体评价和整体部署。富油气凹陷丰富的待发现油气资源,不同区带、领域间油气勘探的不均衡性奠定了实施"二次勘探"的基础;油气成藏理论与认识的发展为"二次勘探"提供了理论指导;高精度三维地震重新采集与连片处理等勘探技术的快速发展与广泛应用,为"二次勘探"提供了强有力的技术支持。更多还原

【Abstract】 Secondary exploration is a new petroleum exploration idea and method for oil-rich sags. Essentially it is the reappraisal of the distribution law of undiscovered petroleum resources in oil-rich sags. The core is to cognize, evaluate and deploy on the whole. Oil-rich sags have favorable conditions for carrying out secondary exploration, which include abundant residual petroleum resources, and unbalanced exploration in different zones and domains. New exploration theories and recognitions provide theoretical guides for secondary exploration. High accuracy acquisition techniques and large area processing techniques of 3D seismic data have witnessed a rapid development and have been widely applied, providing strong technical support for secondary exploration.更多还原
