AVO技术正演特征研究

Forward modeling of AVO Technology

AVO技术是油气勘探中十分有效的技术手段,在流体识别、裂缝检测等方面应用广泛;前人利用AVO技术在煤层裂缝检测,煤层厚度研究以及煤层气识别上取得一定的研究成果。本文在前人的研究基础上,建立煤层的AVO正演模型,研究了煤层顶底界面的AVO曲线特征,其煤层裂缝及煤层气对煤层AVO特征的影响,对煤层勘探有一定的指导意义。

AVO technology is very effective in oil and gas exploration, widely used in the fields of fluid identification and crack detection; previous studies show that： AVO technology is also widely used in coal seam crack detection, coal seam thickness and the coal seam gas identification. On the basis of previous research, the establishment of coal seam AVO forward model, study the characteristics of coal seam AVO curve of the top and bottom interface, the influence of coal seam crack on AVO characteristics of coal and coal seam gas, has a guiding significance to coal exploration.
