摘要
随钻地质导向是目前复杂油气藏开发的高端应用,三维井筒可视化是其关键基础技术之一.基于随钻获得的井斜工程数据和测井地质属性数据,研究了建立均径井筒和非均径井筒模型的方法,采用成像原理实现了地质属性的可视化表达,并实现了井筒模型和地层可视信息的有机融合,即在井筒壁上显示钻遇地层的属性信息.基于OpenInventor对该方法进行了原型实现,实际运行测试表明,系统能形象、直观、准确地从井筒中观察钻遇地层情况,为随钻地质导向的实现奠定了基础.
Geosteering while drilling is a high-quality application of complex reservoirs development, and 3D visualization of wellbore is one of the essential and indispensable technologies for it. The methods of modeling wellbore which have equable or unequable radius are researched, and the visualization of geological properties is achieved by using imaging principle, based on the well inclination data and well logging data getting from LWD. Then the 3D wellbore model and the imaging information would be combined together, which means showing the drilling stratum attributes in the wall of the wellbore. A system model is implemented based on Open Inventor, of which running tests show that attributes of drilling stratum from wellbore can be observed vividly and accurately, and it laies a solid foundation for the implement of geosteering while drilling.
