模型反演技术在浅层储集层研究中的应用

反演技术是目前用于储集层预测的重要手段。该方法的实质是将常规的界面型反射剖面转化为岩层型测井剖面，为地质学家直接研究储集层横向变化提供方便。我院1998年引入的荷兰Jason公司的Invermod模块便是实现上述转化的技术之一。从简单介绍反演基本原理及Invermod工作流程出发，指出非阻抗反演与波阻抗反演结合使用，对识别薄层更为有效。通过一年的开发和在神泉油田支储集层预测中的应用，取得了较好的效果。

Application of Invermod Technique to Reservoir Study in Shenquan Oilfield

Inversion technique is an important tool used in reservoir prediction at present- The technic principle is to convert conventional contact-type reflection profile into stratigraphic log response, providing convenience of direct research areal reservoir variations. The inversion module introduced from Jason Company in Holland in 1998 is one of techniques intended to realize the conversion. This paper briefly introduced basic principle and working flowsheet, and suggested that using nonimpedance inversion combined with wave impedance to investigate thin layer will be more effective. After applied for one year in development and prediction of shallow reservoirs in Shenquan oilfield, better results have been obtained by using Invermod technique.
