摘要: 露头储层沉积体系的准确划分是建立储层地质知识库和研究随机建模方法的基础和关键.储层岩石相的模拟与预测是储层沉积学和油田实际生产的主要课题之一,通过对扇三角洲露头岩石相的模拟研究,总结出了该类扇三角洲沉积体储层建筑结构的模拟与预测方法,经对不同岩石相多种模拟方法的试运算,给出了对于该类沉积体系的最佳模拟方法,并通过实际检验证明是可信的.在本研究中,随着井距的扩大,原始数据点的减少,沉积相模拟的效果逐渐变差,但是该方法能够反映扇三角洲沉积相的分布规律,特别是扇三角洲平原亚相,基本可以恢复露头的原模型.

Abstract: Exact classification of the outcrop depositional system is the base for building geological knowledge data-base and studying stochastic simulation.Simulation and prediction of reservoir lithology is one of the main subjects of reservoir sedimentology and oilfield production.By fan-delta lithology simulation study,a set of technology about reservoir structure simulation and prediction of fan-delta had been established.Through test calculation of different lithologies by using many simulation methodogies,the best simulation methodology for this depositional system had been determined and it is proved to be reliable by practice.With the widening of well spaces and the sparsity of original data,the simulation precision of depositional microfgces decrease gradually.The SIS method can reflect the distribution of fan-delta microfaces,especially the fan-delta plain,and the outcrop prototype model can be basically rebuilt.

Key words: lithology, simulation, fan-delta, proto-type model
