【摘要】测井曲线作为测井和地震相结合的桥梁,是测井约束反演的基础和核心。测井曲线的准确性决定了整个反演工作的成败,因此需要在前期通过曲线预处理来保证测井曲线的准确性。在煤田波阻抗反演中通过测井曲线预处理,提高了反演成果的精度。更多还原

【Abstract】 As the bridge of combining seismic with logging,logging curve was the the basis and core of inversion with well log constraint.The success or failure of inversion work was determined by the accuracy of logging curve,so it was required to ensure the the accuracy of the curve through pretreatment in the prophase.The accuracy of the inversion results was improved through pretreatment of logging curve in the impedance inversion of coalfield.更多还原
