摘要
塔河油田盐体覆盖区下奥陶统碳酸盐岩埋深大,储层非均质性强,给储层预测带来极大的难度。波形分析法根据碳酸盐岩储层裂缝和孔洞结构特有的非均质性,建立地质模型,结合地震波形分析和反射机理研究,确定储层与地震响应之间的对应关系,进而对未知区域作储层预测。塔河油田的应用实例表明了这种方法的有效性。
The deep Ordovician series carbonate rocks that are underlying salt bodies are characterized by strong heterogeneity, challenging the interpretation of carbonate reservoirs. Based on an analysis of the heterogeneity caused by fractures, karst and caves in carbonate reservoir, this paper proposes to establish the relations between carbonate reservoirs and seismic responses with waveform analysis. Reservoirs are predicted. The feasibility of the method is demonstrated on real data from Tahe Oilfield.
