摘　　要：本文扼要介绍了油气放射性勘查的历史和现状,着重叙述了勘查模式的基本论点:油气藏边界(油水界面或气水界面)在相应地表所反映的放射性异常,一般要高于油气田顶部地表附近所反映的放射性异常(场),而后者相对于围岩的放射性场,则随着不同地区地质条件、地球化学环境和放射性元素本身特点等因素的不同而异。即有时反映相对高场,有时则是低场。异常在平面上的反映形式有:环状、串珠状、面状、以及其它复合状。文章最后列出6个例子说明模式应用的可行性。After briefly introducing the history and present status of radioactive exploration for oil and gas, this paper emphatically describes the fundamental view on exploration model. The view includes that radioactive anomalies(fields) reflected from the corresponding surface at the boundary(oil-water or gas-water interface) of oil and gas deposit are generally higher than those reflected from the surface adjacent to the top of oil and gas fields; the latter are different with variations of various factors such as geological conditions, geochemical environments in different regions and the features of radioactive elements themselves, that is, radioactive anomalies sometimes indicate relative high, sometimes, relative low. The anomaly patterns reflected on the plan are ring, bead-like, planar and other composite shapes. At the end of this paper six examples are enumerated to illustrate the feasibility for the model application.
