摘要
在陆相碎屑岩储油层内部非均质比较严重,油层内部常常夹有泥岩、粉砂质泥岩等低阻夹层,有些油层内还有较薄的钙质层条带等高阻夹层,它们不含油或对工业油流没有贡献,在划分油气层有效厚度时应扣除。根据这些夹层在测井曲线上的响应特征,采用微电极和八侧向测井曲线,研究了其对应的扣除方法,使有效厚度划分更加准确,提高了油气储量的计算精度。
In land facies detrital reservoirs,mudstones and silty mudstones with low resistance are very common,and sometimes thinner calcareous interlayers with high resistance are also found,resulting in strong nonhomoge-neity.Those interlayers are oil free or not contributive to commercial oil and gas flows,hence should be deducted when calculating the effect thickness of reservoir.The deducting method of interlayer thickness has been studied based on micro-electric-log and Laterolog 8,improving the reliability of effective thickness calculation and reserve prediction.
