摘要
过套管电阻率测井是一种测井新技术,能在普通的金属套管井中测量地层电阻率,在油藏监测和剩余油气资源评价方面展现了独特的优势。由于套管和地层之间存在水泥环,过套管电阻率测井不可避免地受到水泥环的影响。利用修正的传输线方程,采用数值模拟方法,全面分析了水泥环厚度和电阻率对俄罗斯过套管电阻率测井仪(ЭКОС)的影响,建立了一套水泥环影响校正图版;并且编制了相应的计算机程序,实现了ЭКОС水泥环影响校正的自动处理。
Formation resistivity logging through casings was a new technology of well logging.It had distinctive advantage in reservoir monitoring and residual oil-gas resource evaluation.Because of the cement sheath between casings and formation,the data of formation resistivity through casings were affected inevitably by cement sheath.The influences on Russian resistivity log tool through casing from thickness and resistivity of cement sheath were systematically analyzed by numerical simulation based on modified transmission-line equation,and a set of chart-boards for correcting cement sheath influence were built.According to the chart-boards,a corresponding computer program is developed to realize the correction of cement sheath for Russian resistivity log tool through casing,which runs automatically to increase work efficiency.
