推出一种新型底部钻具组合(BHA)及利用连续油管进行分支井修井作业技术。由于BHA工具穿过分支井段并不安装在井内进行完井 ,因此 ,BHA的作用就是通过裸眼井或下套管井的连接点进行智能导向。其导向成功的关键取决于连接点处的几何尺寸。
Introduced a new type of bottom hole assembly (BHA) and coiled tubing for branch well servicing. Since the BHA tool does not penetrate the branch wellbore to complete the well, the role of the BHA is to be intelligently guided through the connection point of the openhole or cased well. The key to its success depends on the geometry of the connection point.
