油气化探中△C与烃类异常的相互配置关系

A MUTUAL DISPOSE RELATION BETWEEN EPIGENETIC CARBONATE (△C) ANOMALY AND HYDROCARBON ANOMALY IN GEOCHEMICAL EXPLORATION FOR OIL GAS

通过对△Ｃ（即后生碳酸盐）成因机理的分析，结合典型实例，对△Ｃ异常与烃类异常的相互配置关系及其与地下深处油气藏联系的研究，大量事实证明，△Ｃ异常并不总是与烃类异常一致的，只有当△Ｃ异常与烃类异常较一致时，△Ｃ异常才具有找油气藏的意义。

On the basis of analysis to genetic mechanism of epigenetic carbonate (△C),combined with the typical example,the mutual dispose relation between △C anomaly and hydrocarbon anomaly and its relation to the oil gas underground were detailly discussed.In fact,the △C anomaly was not always identical with the hydrocarbon anomaly .The △C anomaly can just have significance for oil gas exploration,only as it is relatively consistent with hydrocarbon anomalies.
