复杂断块油藏精细构造解释和应用效果

Fine structural interpretation for complex fault block oil reservoirs and its application effect

随着油气勘探开发工作不断深入,断裂系统复杂的小断块油藏已成为油田增储上产的研究对象。如何有效利用三维地震资料,准确发现和落实复杂断块构造是油气勘探工作中的重要环节。本文针对传统的复杂断块构造精细解释工作存在的问题,以三维可视化为基础,结合方差体技术,提出开展复杂断块构造精细解释的方法与流程。此方法在潜江凹陷应用中,取得良好效果。

With the deepening of the petroleum exploration and exploitation,complex fault block oil reservoirs have been the research target for increasing oil reserves and productions. How to use the 3D seismic data to find and verify some complex fault block structures exactly is an important link for oil and gas exploration. Aiming at some problems in traditional interpretation about complex fault block structures,based on 3D visualization and combined with variance cube technique,this paper has provided the method and process of fine interpretation for complex fault block structures. This technique has gained good effects when being applied in Qianjiang Depression.
