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。 Logging curves, as a combination of logging and seismic logging, are the basis and core of logging constrained inversion. The accuracy of the logging curve determines the success or failure of the entire inversion work. Therefore, it is necessary to ensure the accuracy of the logging curve by pre-processing the curve in the early stage. Through logging curve pre-processing in the impedance inversion of coalfields, the accuracy of the inversion results is improved.
