So field experiments of borehole SP logging in the steel cased Wells are made in Daqing petroliferous area.
为此，大庆油区进行了钢套管井井内自然电位测井现场试验。
SP logging is one of logging methods which can effectively distinguish resistivity of mixed liquid in formation after oil layer being water flooding.
自然电位测井是油层水淹后能够有效识别地层混合液电阻率信息的测井方法。
