摘要

以塔河油田碳酸盐岩储集层的孔隙空间结构所特有的非均质性为出发点,根据碳酸盐岩岩溶储集体的形态、规模、组合形式、距奥陶系风化面的距离等,设计了多种碳酸盐岩缝洞型储集层理论地质模型和实际地质模型,研究波形的全方位特征及合成机理,通过正演模拟,结合钻井、测井等资料,获取了塔河油田碳酸盐岩缝洞型储集层发育度与地震波形特征的对应关系。根据建立的碳酸盐储集层地震识别模式,对塔河油田地震资料进行了全方位的波形特征识别与追踪,编制了研究区各类波形异常及碳酸盐岩缝洞型储集层级别分类图,利用波形分析技术和钻井资料对塔河油田碳酸盐岩缝洞型储集层进行了有效预测,在塔河油田实际应用中,取得了良好效果。
The theoretic and actual geological models are developed based on heterogeneity or anisotropism of carbonate reservoir in Tahe oilfield, and its karst body's shape, scale, combination and distance apart from the Ordovician weathered surface, etc., in order to study the omnidirectional characteristics and synthetical mechanism. The corresponding relationship between degree of fissure-cavity reservoir development and character of seismic waveform is acquired. The category charts of various waveforms abnormities and such a reservoir are worked out. Effective prediction of such a reservoir is made using waveform analysis technology and drilling data. Case study shows good results for this technique application to the seismic development and drilling allocation in Tahe oilfield.
