注硼中子寿命测井技术在濮城油田的应用

Application of boron injection NLL technology in Pu-cheng oilfield

注硼中子寿命测井是中子寿命测井方法的发展,是为解释产层水淹程度而开发的一项技术。注硼中 子寿命测井是用硼元素作为一种示踪剂,用中子寿命进行"测-注-测"施工,根据两次测井曲线幅度之间 的变化,直接评价射孔井段内地层的水淹状况,找出水层和潜力层,现场应用效果良好。

Boron injection neutron lifetime logging (NLL) is a new NLL technology that has been developed to solve the logging problems in mature oilfields where part of the pay zones are strongly watered out. Boron injection NLL technology uses boron element as tracer and performs ' log -inject- log' operation by using neutron lifetime. It directly evaluates the water out behaviors of formations in perforated intervals and identifies water yield zones and potential pay zones according to amplitude variations between the two logs.
