| 摘 要： | ReelWell钻井是一种新的控压钻井技术,主要由双壁钻杆、滑动活塞、双浮动阀等组成.钻井液从双壁钻杆环空泵入井内,并从内部钻杆返回,能够实现钻井液的闭路循环及对井底压力的精准控制.该技术具有井底压力精确控制、钻井液微流量控制、井眼清洗、水力加压钻头、井底压力隔离、保护储层的特征,对于控压钻井、大位移井钻井、海洋深水钻井、无隔水管钻井、尾管钻井,提高钻井安全性与作业效率以及有压力挑战性的地层钻进方面具有较大的潜力和优势.文章详细地分析了ReelWell钻井的系统组成、工艺原理、特点及其应用情况,并建议我国结合实际情况,尽快开展这方面的相关配套钻井技术研究.

| Abstract: | Reelwell is a new managed pressure drilling technology,the main component is double-wall drilling pipe,sliding piston,dual floating position valve etc. The drilling fluid pump into the annulus of double-wall drill pipe and return to inner drill pipe,thus closed loop circulation and precise downhole pressure control could be achieved. The Reelwell technology has the features of precise downhole pressure control,fluid micro-flow control,hole cleaning,hydraulic weight on bit,bottom hole pressure isolation,and ... |
