突变理论及其在油气检测中的应用

Catastrophe theory and its application to hydrocarbon prediction

本文详细阐述了尖点突变理论，在此基础上建立了尖点突变模型和累加尖点突变模型，提取其实跳势、突跳间隔、突跳时间等参数；然后将突变理论应用于油气检测，并探讨其各参数的地质意义，发现突跳势、突跳时间曲线与油气分布呈一定程度的正相关关系。由此可见，利用突变参数进行油气检测是可行的。

Point catastrophe theory is detailed in the paper. The point catastrophic modeland the accumulative point catastrophic model are described here, from which onecan derive some parameters such as catastrophic potential, catastrophic interval,catastrophic time and so on. This catastrophic theory is introduced to predict hydro-carbon- Authors also illustrate definite geological meanings of some parameters. It isfound that catastrophic potential curve and catastrophic time curve show positive cor-relation to hydrocarbon distributi0n. Hydrocarbon prediction using catastrophic pa-rameters is thus feasible.
