摘　　要：结合吐哈油田的地质特点 ,推导出了低孔低渗透低矿化度砂岩储层的饱和度方程和产层进入两相流动的分流量方程 ,对有关参数进行了研究 ,并在测井工艺、解释方法上进行了较大改进 ,解决了注硼中子寿命测井中未进硼层解释不准的难题。对部分油井的油层水淹级别进行了评价 ,并计算了各层的含水率 ,经过 2 8口井卡堵水措施验证 。From the geologic characteristics of Tuha Oilfied, the saturation equations of sandstone reservoir with low porosity, low permeability and low salinity, and subflow rate formulas of two phase flow in pay zones are derived herein. Meanwhile, the relevant parameters are studied. The technology of boro injection neutron lifetime logging and its log interpretation method are fairly improved so that the incorrectly interpreted zones without boron imbibition have been successfully interpreted. After evaluating waterflooded level in oil zones for part of oil wells and calculating each pay zone′s water cut, the measures of water shutoff for 28 wells are implemented. Field logging examples show that using boro injection neutron lifetime logging to determine water cut in pay zones in Tuha Oilfield with low porosity, permeability and salinity is a better logging technology.
