    • A tubular string is advanced with a bottom hole assembly as the hole is drilled and reamed in a desired direction with the aid of directional drilling equipment adjacent the bit. When the advanced tubular forms the desired lap to the existing tubular, the assembly can be configured to cement the tubular and expansion can then be accomplished to fill the annular space and enhance the cement bonding. The expansion equipment can create a bottom bell on the expanded tubular and expand the top end into a bell of the existing tubular so that a monobore is created as the process is repeated with each added string. Numerous variations are contemplated for each single trip including but not limited to the direction of expansion, whether cementing or expansion occurs first, reforming folded tubing in the hole as well as the nature of the expansion tool and pressure control when drilling.
    • 随着孔与钻头相邻的定向钻井设备的钻孔和延伸在所期望的方向上,一个管状柱带有一个底部孔组件。 当先进的管状物形成所需的搭接线到现有的管状物时,该组件可被构造成使管状物水泥化,然后可以实现膨胀罐以填充环形空间并增强水泥粘结。 膨胀设备可以在膨胀的管子上形成底部的钟罩,并且将顶端膨胀成现有管状物的钟形,从而当每个加入的绳子重复该过程时,产生单孔。 考虑到每次单次行程的许多变化,包括但不限于膨胀方向,首先发生固井或膨胀,在孔中重新形成折叠管,以及在钻孔时膨胀工具的性质和压力控制。
