高勘探程度区富油气凹陷二次勘探方法及应用
|
摘要
渤海湾盆地富油气凹陷油气资源丰富,岩性地层油气藏和隐蔽型潜山油气藏是今后发现规模储量的重要勘探方向。以成藏理论新认识为指导,以先进适用勘探技术为支撑,形成了富油气凹陷"二次勘探"新思路。提出了以"整体认识、整体评价和整体部署"为核心的富油气凹陷二次勘探方法,主要包括构建全凹陷整体三维地震数据平台、重建凹陷构造、沉积和储层等地质模型、油气资源分布量化表征重描、多领域油气成藏模式创建、多领域目标整体预探以及上产增储一体化实施等。该方法的提出,对深化渤海湾盆地富油气凹陷勘探,实现油气勘探持续规模增储,具有现实的指导意义。
Hydrocarbon enriched depressions in Bohai Bay Basin is rich in oil and gas resources. Lithological stratigraphic oil and gas reservoirs and subtle buried hill oil and gas reservoirs are the important exploration targets for discovery of large-scale reserves in the future. Guided by the new knowledge about hydrocarbon accumulation theory and based on advanced exploration technology, Huabei Oilfied Company has developed a new mindset of òsecondary explorationófor hydrocarbon enriched depressions. It also comes up with the secondary exploration method for hydrocarbon enriched depression, which is focused onòcomprehensive knowledge, comprehensive assessment and comprehensive deployment.óThe method includes construction of 3D seismic data platform for the whole depression, re-construction of geological models for the structure, sedimentation and reservoir of depression, re-description of quantitative characteristics of hydrocarbon distribution, creation of multi-area hydrocarbon accumulation models, and unfolding comprehensive preliminary exploration of multi-area targets. This method is of great realistic significance to exploration of hydrocarbon enriched depressions in Bohai Bay Basin and increase of large-scale reserve through sustainable exploration.
