摘要： In aspects, the present disclosure provides a monobore wellbore construction apparatus and method, which in one embodiment may include a series of overlapping expandable liner sections. In one aspect, the overlapping liner sections may be expanded and pressed to provide no gaps along the length of the liner system. In another aspect, the liner sections may include centralizers and/or circumferential seals that provide sealing functions and spaces between the overlapping liner sections. The liner sections may be lined with a suitable sealing material, including an epoxy or may be filled with cement or another desired materials.
摘要翻译：在一些方面，本公开提供了一种单孔井筒施工装置和方法，其在一个实施例中可包括一系列重叠的可膨胀衬套部分。在一个方面，重叠的衬垫部分可以被膨胀和压制，以沿衬垫系统的长度不提供间隙。在另一方面，衬套部分可以包括提供重叠衬里部分之间的密封功能和间隔的中心器和/或周向密封件。衬里部分可以衬有适当的密封材料，包括环氧树脂或可以用水泥或其它所需材料填充。

摘要： A string to be expanded is run in with a running string that supports a swage assembly. The running string is secured to the existing tubular and the top of the string to be expanded is sealed around the supported running string. The pressure applied to the annular space above the seal drives the liner over the swage. A cement shoe is affixed to the lower end of the string that is expanded after becoming detached from the running string assembly. When the expanded liner bottoms on a support, generally the hole bottom, the cement is delivered through the shoe and the expansion of the top of the string into a recess of the string above continues. The swage assembly with the seal and the anchor are then recovered as the running string is removed during the process of expanding the top of the expanded string into the lower end recess of the existing string already in the wellbore.
摘要翻译：要扩展的字符串将使用支持标准组合的运行字符串运行。运行的绳子被固定到现有的管状物上，待膨胀的绳索的顶部被密封在所支撑的行驶绳上。施加到密封件上方的环形空间的压力驱动衬套穿过模具。水泥鞋被固定在弦的下端，该绳的下端在从运行的绳组件脱离后被膨胀。当膨胀衬垫在支撑件上时，通常是孔的底部，水泥通过鞋被输送，并且将绳的顶部膨胀到上述绳索的凹部中继续。随后，在将膨胀的柱的顶部扩展到已经在井眼中的现有柱的下端凹部的过程中，随着运行的绳索被移除，带有密封件和锚固件的挤压组件被恢复。
