摘要
针对同位素示踪测井法中同位素的使用剂量无理论依据、盲目性较高的问题,构建了单孔示踪法测定地下水流向的计算模型,通过室内试验验证了模型的正确性,并结合室内和野外试验分析了射线强度对流向计算精度的影响,给出了流向测量精度与射线强度间的函数关系,克服了工程应用过程中同位素使用的盲目性,具有一定的工程指导意义。
According to the problem of lacking theory basis of using the isotope dose by isotope logging method, the model of groundwater flow measurement is built, and the correctness is examined according to the experiment in door. The influence of ray strength on calculation precision is analyzed according to the experiments in door and in field. The function relationship between measurement accuracy and radial intensity is also given and it overcomes the blindness of using isotope in engineering application, which has engineering directive function.
