摘要
虚拟现实技术是近几年发展起来的一门新兴的综合技术,简要介绍了虚拟现实的特点和国内外研究和应用现状,并以鄂尔多斯盆地塔巴庙区块为例,重点探讨了虚拟现实技术在该区地震资料构造解释和储层预测方面的应用。实践表明,运用该技术能够在交互的状态下实时完成层位的全三维自动追踪解释,并通过体透视、子体检测、地质异常体雕刻和属性提取等技术,研究储层空间展布特征进而预测含气富集部位。这一新技术在鄂尔多斯盆地塔巴庙区块应用结果显示,它可以减少地震资料解释的周期,增强三维解释的准确性,提高储层预测的效率,已取得了显著的地质效果,该技术在油气勘探中有广阔的应用前景。
Virtual Reality (VR) technique is a new synthetic technique developed in recent years.The purpose of this paper is to introduce briefly some features and recent research of VR technique,and discuss in detail its applications in tectonic interpretation of seismic data and in the prediction of reservoirs in the Tabamiao region in Ordos Basin.Our studies showed that VR technique can be used to interpret horizons through auto-picking in interactive and real-time status,to study the spatial distribution of reservoirs,and to predict the distribution of gas-bearing favorable areas with VR techniques, such as three-dimensional object perspective,small object inspection,geologic abnormality sculpture, and attribute extraction.In conclusion,our results reveal that through the applications of VR technique, the interpretation cycle time can be decreased,the accuracy of 3D interpretation can be increased,the efficiency of reservoir prediction can be improved, and positive geological results have been obtained in exploration and production of gas in the Tabamiao region of the Ordos Basin.The VR technique has great application prospect in oil and gas exploration.
