摘　　要：注硼中子寿命测井是近年来发展起来的确定剩余油饱和度,判断水淹层的一种测井方法,但是由于中子寿命测井仪要用到中子发生器,价格昂贵,使用寿命有限,同时是一种军工用品,购买受到限制,使得该技术大量推广应用带来困难。文章介绍了注钆代替注硼,中子伽马代替中子寿命的测井方法,对其优点作了分析,并列举了一些实例。In order to determine the remaining oil saturation and identify the water flooded zones,Boron-Injected Neutron Lifetime Logging was developed recently.However,several disadvantages of Boron-Injected Neutron Lifetime Logging restrict its being applied widely.These disadvantages include high price,limited working life,and the order of it is strictly limited because it belongs to military products.In addition,neutron generator is necessary in the logging.This article introduces the new logging method which uses Gadolinium-injecting instead of Boron-injecting and uses Neutron-Gamma Logging instead of Neutron Lifetime Logging.Here are several examples to show the advantages of Gadolinium-Injected Neutron-Gamma Logging technology.
