摘　　要：薄差储层具有"薄、小、散"的特点,储层精细刻画难度较大.本文分析了薄差储层精细刻画的若干问题及对策,重点阐述了4项针对性的关键技术——基于小尺度-高密度的精细构造解释技术、虚拟泥岩层段技术、基于频率补偿的曲线重构技术和基于地震反演的层间属性提取技术.在大庆长垣外围油田M402-3区应用效果证明:综合地震、测井、录井等资料,结合薄差储层预测成果图,实现了薄差储层主力单元沉积微相有效绘制;结合构造、薄差储层地质认识,辅助完成了M402-3区PI1层的水平井地质参数和井轨迹参数设计.因此,笔者提出的技术对策可以作为薄差储层刻画的有效技术手段,为下一步薄差储层含油潜力挖潜奠定了基础.The thin and poor reservoir has the characteristics of＂thin,small and loose＂,the meticulous depiction of the reservoir is difficult. After analysis several problems and countermeasures of the meticulous depiction of the thin and poor reservoir predicts emphases on four pertinence key technology—fine structural interpretation technology based on the small scale-density, virtual mudstone technology, curve reconstruction technique which based on the frequency compensation and layer attribute extraction technology which based on seismic inversion demonstration of application effect in M402-3 Area of Daqing Changyuan Oilfield is proved： Integrated the data of comprehensive seismic,logging and logging,combined with the prediction results of the thin and poor reservoir, the effective plot of the main unit sedimentary microfacies make the effective plot of sedimentary microfacies of main unit of the thin and poor reservoir realized combined with structural, the geological knowledge of thin and poor reservoirs,asstists the design of M402-3 area PI1 layer＇s horizontal well geological parameters and well trajectory parameters. To this end proposed the technical countermeasures can be taken as an effective mean to characterize thin and poor reservoirs moreover it has also laid a foundation of the next step to thin and poor reservoirs＇ potential for oil potential.
