摘要
基于野外地质露头、现代河流展布规律研究结果,通过对典型井组曲流河点坝体几何特征参数的分析,提出了曲流河道点坝体内部侧积夹层识别、描述和侧积体确定性建摸方法,并应用于大庆萨尔图油田南一区甲块水平井设计与实施,夹层的预测精度为76.5%.实践表明,在密井网条件下,该方法用于曲流河点坝砂体内侧积夹层空间展布规律预测和地质模型建立是可行的.
According to the researches of field geology outcrop and the modern rivers distribution law,through analyzing meandering river point bar sandbodies geometry characteristic parameter of the typical well group,this paper proposes the recognition and the description of lateral accretion sandwich interior meandering river point bar bodies,and puts forward a determining modeling method about lateral accretion bodies,and uses it for horizontal well design and the implementation of armor block of south-1 area in Daqing.The practice indicates that this method is feasible,can be used in forecasting the distribution of lateral accretion sandwich in meandering river point bar sandbodies and in establishing the geological model under dense well pattern conditions.
