虚拟现实技术在塔河油田油气勘探中的应用
|
摘要
阐述了虚拟现实技术的基本概念、虚拟现实技术理论和构成虚拟现实系统的软、硬件技术,并介绍了石油行业中虚拟现实系统“Petro-One”的特点和功能。塔河油田碳酸盐岩储集层具有埋藏深、地震反射信号弱和非均质性强的特点,引入虚拟现实系统进行石油勘探研究,在多井空间立体标定的基础上,利用虚拟环境下的精细构造解释技术进行层位追踪,采用多属性分析来预测储集层,并将塔河油田奥陶系大型缝洞体系进行三维可视化及立体刻画,再结合钻井等资料进行塔河油田碳酸盐岩储集层预测,最后对虚拟现实系统发展和应用前景进行了讨论。
The basic concept of the theory of virtual reality technique and its software and hardware are presented.The feature and function of Petro-One of the virtual reality system in petroleum industry are discussed and introduced into the petroleum exploration study of carbonate reservoir in Tahe oilfield,which is characterized by large buried depth,weak seismic reflection signal and high heterogeneity.On the basis of multi-well spatial calibration,the fine structural interpretation in virtual environment and the multi-attribute analysis are adopted to horizon tracking and reservoir prediction,respectively.3D visualization and description are conducted for large-scale fracture-vug system of Ordovician in Tahe oilfield.The carbonate reservoir prediction is made using well data.Finally,the prospects of development and application of such a virtual reality system are discussed.
