隐蔽油气藏勘探对三维可视化技术的需求主要体现在复杂地质界面的三维显示、多学科研究成果的相互印证和三维可视化成果的人机交互等方面。通过对油气勘查三维可视化技术研究现状的分析,提出了以地理信息系统(GIS)为基础平台,通过对成果、三维建模、三维显示和评价过程的反复修正,实现三维可视化技术在隐蔽油气藏勘探中的应用。其中,三维建模技术采用地质统计学方法快速构造三维曲面;三维显示技术包括多个三维图层的联合显示和三维贴图显示技术;三维操作包括三维旋转、平移、飞行模拟等一系列三维图像显示方法。将上述技术综合应用于金湖凹陷隐蔽油气藏勘探中,取得了较好的效果。

The main demands for 3-D visualization in subtle reservoir research are the realization of 3-D display of complicated geological interfaces, inter-verification of multi-discipline research, and interactive visualization, etc. Through an analysis on the new advancement of 3-D visualization technology in oil and gas exploration, the paper put forward a GIS-based solution that can satisfy the demands through a repetitive process of results modification 3-D modeling 3-D display and evaluation. 3-D modeling can make a rapid construction of 3-D curved surfaces by geological statistical methods. 3-D display includes a unified display of various 3-D map layers and 3-D show of paste maps. 3-D operation involves a series of image enhancement methods including 3-D rotation, translation and flying simulation. The above methods and technologies have gotten a good effect in the research of subtle reservoir in JinHu Depression.
