多参数约束反演及其应用

多参数约束反演方法是利用已知测井资料丰富的高频信息和完整的低频信息来补充实际地震记录有限带宽的不足，通过迭代反演来求取一个具有较高分辨率和较宽频带的近似反射邓列，在反演中酌情加入层位信息以控制剖面的信噪比，由于该方法以宽频带的测井资料为约束，因此可直接利用所求得的优化的波阻抗剖面来求取地层岩性等参数，为进一步进行岩性解释和薄储集层的横向追踪，对比，预测提供较可靠的地震依据。

MULTIPLE PARAMETERS CONSTRAINT INVERSION AND APPLICATION

A technique of multiple parameters constraint inversion is presented in this paper. Its core is to obtain an approximate reflection coefficient or wave impedance section of higher resolution and broaded band using ample high frequency and complete low frequency information of known logging to make up for the lack of limited band width of real seismic recording by intervative inversion. Layers information are used in inversion to control signal noice ratio of section. The wave impedance section obtained by width band logging constraint can be used directly to invert lithology parameters and provide more reliable seismic evidence for further lithology interpretation and lateral tracking, correlation and prediction of thin reservoirs.
