土壤ΔC法在综合油气化探中的应用

综合油气化探系指多种化探方法和多种化探指标的联合使用,比使用单一方法和单一指标具有许多优点.多年来我们一直采用综合油气化探.土壤△C法是一个新方法.本文首先就△C的浓度分布特征及其与吸附烃和汞的关系进行讨论;接着阐述了土壤△c在油田上的异常特征;最后论述了土壤△C在综合油气化探中的应用.结果表明,土壤△C法在综合油气化探中是有效的.

THE APPLICATION OF SOIL △C METHOD IN COMPREHENSIVE GEOCHEMICAL OIL-GAS PROSPECTING

The comprehensive geochemical Oil-gas prospecting means the combinedutilization of various geochemical prospecting techniques and varied geocbemicalindicators. It evidently has much more advantages than the mere use of a sin-gle technique or a singe indicator, as is evidenced by our application of thiscomprehensive method in recent years. The soil △C method is a new technique.This paper first gives a discussion on the concentration distribution of △C inrelation to absorbed hydrocarbon and mercury, then describes anomaly charac-teristics of soil △C over the oil field, and finally deals with the application ofsoil △C in comprehensive geochemical oil-gas prospecting. It is proved that thesoil △C method is effective in the comprehensive geochemical oil-gas prospec-ting.
