【摘要】 针对先巴扎地区石炭系小海子组(Cx)碳酸盐岩储层复杂的缝洞系统,设计了溶蚀洞和垂直裂缝两种物理模型。通过对这两种模型的正演记录分析,与实际地震记录响应特征对比认为,裂缝模型能更好地反映该储层特征。最后利用相干体技术和分频解释技术刻画了储层中裂缝和断层的分布。更多还原

【Abstract】 Base on complex carbonate fracture-cavity reservoir of Carboniferous system in Xiaohaizi Formation(Cx)of Xianbazha Area,corrosion cave and vertical fracture models were designed.Through analysis of seismic forward records of these two models,and compared with the response characteristics of real seismic records,it was considered that fracture model can better reflect the reservoir characteristics.Finally the coherence cube technology and the frequency-division interpretation techniques are used to characterize the distribution of fractures and faulted zones in the reservoir.更多还原
