Description

一种旋转导向钻井装置 技术领域
本申请属于地下勘探技术领域，尤其涉及一种旋转导向钻井装置。
背景技术
地下勘探技术(例如石油勘探技术、页岩气勘探技术等)在国民经济事业的发展中起着至关重要的作用，在实地勘探过程中，离不开旋转导向钻井装置。旋转导向钻井装置伸入地下的伸入端包括多种功能单元，这些功能单元包括通信单元、测量单元、导向执行单元等，如何能够对这些单元提供电力对旋转导向钻井装置的正常工作及信息的精准反馈具有至关重要的意义。
由于旋转导向钻井装置的伸入端的职能较多，各种职能机构包覆于多个相互连接的筒体内，如何实现筒体之间安全、可靠的电力连接成为本领域极难以攻克的技术难题；需要注意的是，传统做法是通过电力连接单元经过单通道电力连接单元实现电力连接，传统的做法是将电力传输和通信传输共用同一电力通道，这种传输方法如果不增加复杂的电路设计，极易造成信号的干扰，进而使获取的信息不够准确，严重影响旋转导向钻井装置的勘探性能；除此之外，不同的用电单元所需要的电力特性(例如电压、电流)不同，传统的供电方式却只能供送一种电力。
另外，由于筒体之间往往通过螺纹连接的方式实现彼此的连接，在连接过程中需要的扭矩极大，导致筒体连接处的接电环在连接过程中会产生较大的摩擦力，会使接电环的接线处受力，多次拆装后，极易导致导电通路的短路或者与筒体形成短路。为此，急需要发明一种具有结构简单、形成多路导电通路、导电可靠性高等优点的旋转导向钻井装置。
需要说明的是，上述内容属于发明人的技术认知范畴，并不必然构成现有技术。
