发明名称 Gravity-based casing orientation tools and methods
摘要 Disclosed are systems and methods of orienting wellbore tubulars using gravity. Some disclosed orientation indicating devices include a housing defining a first flow channel and being arrangeable within a wellbore tubular, an orientor movably arranged within the housing and defining a second flow channel in fluid communication with the first flow channel, and an eccentric weight arranged within the orientor and having a center of mass radially offset from a rotational axis of the orientor, the eccentric weight being configured to maintain the orientor pointing in one direction as the housing and the wellbore tubular are rotated, wherein, as the housing rotates, the first and second flow channels become progressively aligned or misaligned.
