【摘要】 利比亚LP区块位于Sirte盆地,该区储层多样,礁体发育,横向相变快,储层展布状况难于预测。通过地震分形技术建立了该区的地质模型。在此基础上,应用叠前反演技术准确预测了礁体发育的范围。同时针对该区开发历史长、油气水关系变化快等特点,通过敏感因子分析,优选叠前参数,建立了一套适合本区实际叠前反演技术。结合区块的开发历史,对油气水的变化规律进行了动态跟踪,利用叠前反演技术实时监控油气的产油气情况以及对下步勘探目标进行优选。该方法在利比亚LP区取得了较好的应用效果。更多还原

【Abstract】 According complexities of LP Block(Lybia) such as diversed reservoir,reef body developed and rapid facies change,etc.,pre-stack inversion technology is designed for accurate prediction on range of reef developed.Through sensitive factor analysis and pre-stack parameter optimization,a suitable and practical pre-stack inversion technology is established in this area based on the facts like a long development history and rapid changes in gas-water relations.The application of this technology has achieved real-time monitoring of oil and gas production situation,changes of water,oil and gas,and oprimization of oil and gas exploration targets for the next step combining block development history.更多还原
