利用测井参数交会法确定油水层下限

以铸体薄片分析其岩性并以试油资料为依据,对自然电位、声波、电阻率测井资料进行标准化校正,选取储集层的电阻率（Rt）、声波时差（△t）、自然电位相对值（ASP）、自然伽玛相对值（△GR）、Sw一含水饱和度（Sw）、孔隙度（垂）等六种测井参数分别交会以确定鄂尔多斯盆地旦八区长4＋5储层的油层、油水层下限,该方法具有简单、实用、便于现场解释与判识的优点,并以正285井为例,说明解释结果和生产实际吻合程度较高。

Use of logging parameters to determine oil, oil-water limit

In order to analyze the casting sheet rock and test data based on oil, natural potential, aoustic, resistivity log data standardization correction, Select the reservoir of resistivity （Rt）, acoustic （At）, the relative value of the natural potential （ASP）, the relative value of the natural gamma （AGR）, Sw-water saturation （Sw）, porosity （Ф）, etc. Logging in the six parameters to determine Ordos Basin DanBaChang4＋5 eight head of the oil reservoir, the water level lower limit, The method is simple, practical, on--site to facilitate the identification and explanation of the benefits, and Zheng 285 wells, for example, explained that the results of actual production and a higher degree of agreement.
