摘　　要：以地球化学和物理化学理论为基础，结合实测酸解烃数据，提出了垂向上酸解烃背景和异常的概念，建立了砂岩、泥岩酸解烃背景的数学模型，提供了垂向上识别酸解烃异常的方法。对依─舒地堑某断陷内两口探井的应用结果表明，用此方法发现的异常与气藏有着良好的对应关系。Based on the theory of geochemistry and physico-chemistry and acidolysis hydrocarbon data, this paper puts forward a concept of vertical acidolysis hydrocarbon background and anomaly, a mathematics model of the background in sandstone and mudstone and a method of distinguishing the anomaly, thereby establishes the spplication base of vertical geochemical prospecting for oil and gas. The results of making use of the method to two exploratory wells in a rift of Yilall-Shulan graben indicate that there is a well corresponding relation between discovered anomalies and gas pools.
