【摘要】 美国哈里伯顿公司的六臂地层倾角测井解释软件SHIVA,采用基于球面映像技术的地层产状计算方法。该方法从视倾斜向量在球面及投影平面上的投影出发,依据同一层面上两个互不相关的视倾斜向量可以唯一地确定一个层面的基本原理,将地层产状的计算转化为映像平面上点的坐标的确定。该方法适用于六臂地层倾角测井仪器的特点。本文详细探讨了基于球面映像技术确定地层产状的基本原理,并分析了该技术在六臂地层倾角测井资料处理中的应用。更多还原

【Abstract】 The logging interpretation software SHIVA of six-arm dipmeter which developed in American Hallibuton Logging Service Company uses calculation method for stratigraphic attitude based on spherical projection technology, which comes from mapping of apparent dip vector on spherical plane and projection plane and transforms the definition of stratigraphic attitude to definition of coordinate of points in mapping plane according to the basic principle that the two incorrelate apparent dip vectors in a same plane can uniquely define a plane. The method is suitable for character of six-arm dipmeter. The paper deeply and in detail approached the basic principle of stratigraphic attitude definition based on spherical projection and analyzed the application of the technology to logging data processing of six-arm dipmeter.更多还原
