多井约束反演技术在东濮文东地区储层预测中的应用

多井约束反演技术Interwell-3D是一种基于三维模型的交互式地震地层反演，具有层位标定、构造解释、快速建模等功能。引入三维地质模型约束机制，以钻井、测井资料为约束，采用网格反演的算法，反演出高精度波阻抗数据体，为进一步研究储层的空间分布、物性特征等提供可靠基础资料。应用该技术对文东地区目标区Es^33-Es^43地层进行了储层预测，对砂体的空间分布、厚度变化、物性特征做了精确描述，与钻井符合较好，为圈定有利储层提供了可靠依据。

The Application of Well Logging-Constrained Inversion Technique to Reservoir Prediction in Wendong Area of Dongpu Depression

Mulri-well logging-constrained inversion technique, that is interwell-3D, is based on the interactive seism-stratum inversion of 3-D model. It possesses functions of horizon calibrating, structural interpretation and rapidly model building etc. It takes 3-D geologic model andlogging data as a constrained condition and adopts arithmetic of gridding inversion to obtain high precise wave impedance and provides the dependable data for further studying spacial distribution and property of reservoirs. Applying the technique predicted reservoir within Es_3~3 ~ Es_3~4 in Wendong area, Dongpu depression, described spacial distribution and thickness variance and property of the sandstone. The conclusion coincides with drilling result very well and provides dependable evidence for searching available reservoirs.
