摘要
本文主要根据克拉玛依油田注水资料、井口采出水矿化度资料和其他生产资料,用数理统计方法给出油层水淹过程中,地层混合水溶液电阻率与含水饱和度的相互制约关系,进而得出地层电阻率随含水饱和度的变化规律。利用这一规律,可以更有效地解释、判定水淹层。
Mainly based on the waterflooding data of the Karamay oil field,the salinity data of wellhead water output and other real production data, this paper applies mathematical statistics to formulate the interactive relations between the mixed formation—water resistivity and the water saturation during water—flooding, thus, to establish the variation patterns of the formation resistivity via water saturation. These patterns,along with the resistivity data , can be used to interprete and determine the waterflooded layers more effectively.
