摘要
针对塔河油田石炭系卡拉沙依组砂岩储集层埋藏深、砂层薄、横向变化快、非均质性严重、地震识别困难等问题,通过对地震资料提频,利用地震切片、曲线重构下的测井约束反演和相控储层预测等多手段技术综合分析,将地震属性和反演波阻抗有机结合,指导储集层砂体相控解释,确定了含油砂体的空间展布与描述.实践表明,该方法能有效地利用地震数据体进行薄层储集体预测.
The Carboniferous Kalashayi reservoir in Tahe Oilfield is characterized by great buried depth,thin sand-layers,great lateral variation,strong heterogeneity and difficult seismic identification,so the spatial distribution of thin oil-bearing sandbodies in the reservoir is predicted by using the multi-means comprehensive analysis method of seismic data frequency-increasing,seismic slice,logging curve reconstruction,logging constrained inversion and facies-controlling reservoir prediction. The method is combining seismic attributes with acoustic impedance inversion to guide the interpretation of facies-controlling sand-bodies. Practice proves that the method can effectively utilize seismic data to forecast thin reservoir bodies.
