【摘要】 本文针对敖南储层特薄、非均质性强等特点,在沉积特征分析的基础上,应用地震波阻抗反演与岩性预测、序贯指示或序贯高斯相控随机建模方法及综合地震相、沉积微相、岩心单井相和测井相的地质综合分析方法,对敖南油田特低丰度低渗透薄互储层进行了精细预测。经完钻的水平井验证,薄差层储层预测精度达到87.5%,满足了特薄层水平井优化设计、钻井与开发的要求,使储层预测突破到1m以下的薄差层,该方法适合大庆外围特低丰度低渗透薄互储层,是薄层水平井开发的关键技术之一。更多还原

【Abstract】 The purpose of the paper is to accurately predict low abundance and low permeability thin reservoir of Aonan by using seismic inversion,lithology prediction,sequential index and random geological model building under facies controlling,and integrated geological analysis combination of seismic facies,microfacies and core facies on sedimentation facies analysis.The prediction have met the request of horizontal wells’ design and drilling success in specially thin reservoir.更多还原
