摘　　要：利用石油勘查放射性测井资料开展砂岩型铀矿调查评价是获得深部铀矿化信息的一个有效手段。在实际工作中,由于找矿目的层位不同,很多油田浅部1000 m以内自然伽马资料缺失。提出在油田工作中进行铀矿调查评价的一种新方法“油田石油孔老井伽马复测技术”,该方法是利用油田作业队在对措施井检泵或者维修取出抽油杆时,利用FD-3019探管进行放射性测量,从而达到搜集石油老井放射性异常,是采油区快速获取铀矿化信息的一种高效的技术手段。因此,利用“油田石油孔老井伽马复测技术”是一种在油区进行铀资源调查评价的可行且高效的方法。It was an effective method to carry out the deep sand stone type uranium deposit information by using the radioactive logging data of petroleum exploration to develop the survey and evaluation for uranium.In actual work,for the different position of ore prospecting,the data of natural gamma ray within 1000 m in the shallow part of many oil fields were missing.A new method of“gamma ray reiteration technology for the old oil wells”for the survey and evaluation of uranium deposit in oil field work had been proposed,the method used the FD-3019 probe tube to carry out the radioactive measurement when the oil field operation team checked the pump or removed the sucker rod in the measure well,so it could collect the radioactive anomalies in the old oil wells,which was an efficient technical means to quickly obtain the uranium mineralization information in oil production areas.Therefore,it was a feasible and efficient method to survey and evaluate the uranium deposit in the oil fields by using“gamma ray reiteration technology for the old wells that were in oil fields”.
