摘　　要：通过近几年的研究，寻找油气藏的放射性方法技术取得了较大进展。在数据采集技术方面，以γ能谱测量和电离室α杯法为主，采用自行研制的微机化仪器开展高灵敏度、高精度、多参数数据采集，可以快速提供多种参数。在数据处理研究中，以地面放射性测量工作站为基础，利用成图成像、人机交互处理与解释等技术，初步形成了油气藏上方放射性测量数据的预处理和异常分离方法。应用上述方法技术，在四川进行了放射性方法找油气的试验，预测了产油气有利区，初步取得了成功。实践证明，放射性方法是一种简便、快速、经济、实用、安全的找油气方法，其推广应用可望取得良好的经济效益。Through the research in recent years,much progrcss has been made in applying radioactivity to hydrocarbon's detection. By mcans of γ spectroscopic analysis and ionization chamber α-cup method, our data acquisition is dcsigned to perform on a selfdeveloped microcomputerized instrumcnt, with which multi-parameters can be rapidly acquired in high-precision. In data processing,many techniques including imaging, interactive interpretation are adopted to run in a surface workstation of radioactivity survey, through which the techniques for data prc-processing and anomaly separating are tentatively developed. As a result of applying the above mentioned techniques to the trial of radioactivity survey in oil/gas detection, we have successfully predioted some prospecting areas in Sichuan Province. Practice shows that the radioactivity survey should be a good method in oil/gas detection, whose properties of rapidity,economy,practicality and safety may result in dramatic cconomic benefits.
