钻井地质设计的科学性、准确性和可操作性的高低,直接影响钻井工程的质量,也决定了整体钻探工作的成败。随着计算机三维图像技术的发展,在钻井地质设计中,利用Earth Vision软件可以建立工区三维地质构造模型、砂体模型及井身轨迹空间展布模型等三维数据体,利用三维地质数据体,设计人员可全方位地分析工区地质构造、掌握地质构造特征、对比地层层位、预测地层压力、合理设计钻井液密度。井身轨迹的可视化,为地质设计中进行防碰提示、防斜预警及修改、补充地质设计提供了重要参考依据。
The scientific, accuracy and operability of drilling geological design directly affects the quality of drilling engineering and also determines the success or failure of overall drilling. With the development of computer 3D image technology, in 3D geological well drilling design, three-dimensional data bodies such as 3D geological structure model, sand body model and borehole trajectory model can be established by using Earth Vision software. With 3D geological data body, The staff can comprehensively analyze the geological structure of the work area, master the geological structural features, compare the stratigraphic positions, predict the formation pressure, and design the drilling fluid density rationally. The visualization of borehole trajectory provides an important reference for anti-collision warning, anti-ramp warning and modification in geological design and supplementing geological design.
