The Pretreatment of Log Curve in Wave Impedance Inversion of Coal Field

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.
