    • A method (100) of enabling at surface orientation data transfer from a contactless orientation system (11) coupled with an inner core tube (12) to one or more record carriers on or associated with a core sample (14) held in the core tube, the core sample (14) having a longitudinal core axis (16) and a core face 18 accessible from an end of the inner core tube (14), involves three broad steps. A first step is to couple an instrument guide (20) to the end of the core tube (12) from which the core face (18) is accessible so that an axis (26) of the guide is parallel to the core axis (16). A second step is to generate correlation information between a rotational orientation of a known point P on the instrument guide (20) or an instrument (28a) supported by the instrument guide (20) about the guide axis (26) and core orientation data known to the contactless orientation system (11). A third step is to use or otherwise operate the instrument (28a) to: act as the record carrier; or generate the record carrier provided with the correlation information enabling orientation of the core sample (14) to its in-situ orientation when released from the core tube (12).
    • 一种使表面取向数据从与内芯管(12)耦合的非接触式定向系统(11)转移到芯样品上或与芯样品相关联的一个或多个记录载体的方法(100) (14)保持在芯管中,具有纵向芯轴(16)和可从内芯管(14)的端部接近的芯面18的芯样品(14)涉及三个宽步骤。 第一步是将仪器引导件(20)联接到芯管(12)的可从其接近芯面(18)的端部,使得引导件的轴线(26)平行于芯轴线(16) )。 第二步是生成仪器导向器(20)或由仪器导向器(20)支撑的仪器(28a)上已知点P围绕导向轴(26)的旋转取向与已知的芯取向数据 到非接触式定向系统(11)。 第三步是使用或以其他方式操作仪器(28a)以:充当记录载体; 或产生提供有相关信息的记录载体,当从芯管(12)释放时,使得芯样品(14)能够取向成其原位取向。
