摘要
针对琼东南盆地崖南凹陷盆地成藏条件和油气聚集规律复杂、目标埋藏深、储层横向变化大、处于压力过渡带以及物性非均质性强的特点,在充分研究储层特征和对比精选储层预测与油气检测技术的基础上,运用声波阻抗反演和频谱成像分析、吸收衰减分析等技术,对三亚组岩性油气藏储层空间展布进行了精细描述,圈定了有效储层的分布区域,确定了油气藏勘探的有利区带和目标,取得了良好的应用效果。
The Yanan sag of Qiongdongnan Basin is located in pressure transition zone,and it is characterized by complicated reservoir-forming conditions and oil & gas accumulation rules,deeply buried targets,great lateral variation of reservoir,and strong physical heterogeneity.On the basis of fully study of reservoir characteristics and selecting the technology for reservoir prediction and oil & gas detection,the spatial distribution of lithologic reservoir of Sanya Formation is described,the distributed areas of effective reservoir are confirmed,and favorable zone and targets for oil and gas reservoir exploration are identified,by using the acoustic impedance inversion technology,the spectral imaging analysis technology,the technology for analysis of attenuation by absorption and other technologies.
