复杂地质条件下的地震,测井资料综合约束反演

利用测井资料中垂向分辨率和地震资料横向密集采样特点的综合约束反演技术，极大地提高了波阻抗剖面的分辨率。反演依靠一维合成声波测井的结果，以地震地质解释的成果为约束，顺层横向递推形成初始波阻抗模型。然后，以声波测井曲线的外包络为约束，不仅加快了反演的收敛速度，而且使反演结果与实际值更加接近。该方法在陡倾斜和多断层的复杂地质条件下，比其他宽带约束反演方法具有更好的实用性。

Comprehensive Well and Geological Constrained Seismic Inversion Under Complex Geological Condition

Comprehensive constrained inversion makes full use of detailed vertical resolution of well data and horizontal dense sampling, greatly improves resolution of impedance profile greatly.Combined with the result of one dimensional synthetic acoustic curve and seismic geological interpretation,comprehensive constrained inversion forms primitive impedance model along with layers.Then constrained by encircle of acoustic curves, comprehensive constrained inversion not only makes convergence quickly but also makes inversion result closely to reality.This method has better practicability than other Board Constrained Inversion under sharp layers and multi faults condition.
