摘要
以川东建南气田区为例,在综合测井和地质资料的基础上,从AVO正演模拟入手,分析了含气碳酸盐岩储层的AVO异常响应特征。在AVO截距与斜率交会图上,含气碳酸盐岩样点位于第4象限;AVO技术能够分辨的含气碳酸盐岩储层的最小厚度为10m。这些认识对应用AVO方法检测碳酸盐岩地层的含气性具有重要作用。
Taking the Jiannan gasfield area in eastern Sichuan basin as an example, the abnormal AVO responses to carbonate gas reservoir are analyzed according to comprehensive well logging and geological data and AVO forward modeling. The sample points of gas-bearing carbonate rock are located in the 4th quadrant on the crossplot of AVO intercepts and slopes, and the least reservoir thickness resolved by the AVO technique is 10 meters. These results are important to predicting gas potential in carbonate rocks by AVO techniques.
