摘要： An expandable threaded connection between segments of expandable tubulars that provides a high bearing pressure seal at a specific area along the pin and box members is disclosed. The invention utilizes a “groove” in a surface of the box member and a corresponding “rib” on the pin nose. The radial expansion of the tubulars causes the pin to become shorter in length, thereby causing the pin nose to retract from the back of the box member. As the pin nose retracts, the rib on the pin nose moves backward until a portion of the rib contacts a portion of the groove in the box member. The point of contact between the rib and the groove creates a metal-to-metal seal between the pin and box members. Because the point of contact between the rib and the groove is a relatively small area, the force acting on the point of contact generates a high bearing pressure that is equal to or greater than the internal pressure within the expandable tubulars and, thus, generates a high pressure seal.

摘要： An expandable threaded connection between segments of expandable tubulars that allows the threaded tubular connection to withstand the stresses and deformations imposed on the connection by the tubular expansion process is disclosed. The present invention is a unique hybrid threaded connection that utilizes two complementary thread segments to form the expandable threaded connection. The first segment of the threaded connection utilizes standard box and pin threads such that the threads on the pin member in the area of the first segment fully engage the mating threads on the box member. The second segment of the threaded connection has the threads machined on the pin member in a manner such that material is removed from the stab flank of the pin threads to reduce the standard width of the pin threads. In contrast to the pin threads of the second segment, the box threads of the second segment are standard thread width and, thus, are the same thread width as the box threads in the first segment. The use of the reduced thread width in the pin threads of the second segment allows for a loose fit between the pin threads of the second segment and the box threads of the second segment. As the threaded connection is expanded, the loose fit between the pin and box threads of the second segment allows radial and axial movement between the pin and box threads of the second segments of the threaded connection without causing disengagement of the threaded connection. The disclosed hybrid threaded connection thus utilizes multiple thread segments in which the second thread segment accommodates the stresses and deformations generated by the radial expansion process while the threads of the first segment maintain the coupling strength and the pressure integrity of the threaded connection.
摘要翻译：公开了一种可扩展管状部分之间的可扩展螺纹连接，其允许螺纹管状连接经由管状膨胀过程承受施加在连接件上的应力和变形。本发明是独特的混合螺纹连接，其利用两个互补螺纹段形成可扩展螺纹连接。螺纹连接的第一段使用标准的盒和销螺纹，使得第一段的区域中的销构件上的螺纹完全接合箱构件上的配合螺纹。螺纹连接的第二段具有在销构件上加工的螺纹，使得材料从销螺纹的刀头侧面移除以减小销螺纹的标准宽度。与第二段的销螺纹相反，第二段的箱螺纹是标准螺纹宽度，因此与第一段中的箱螺纹具有相同的螺纹宽度。在第二段的销螺纹中使用减小的螺纹宽度允许在第二段的销螺纹和第二段的箱螺纹之间松动地配合。当螺纹连接膨胀时，第二段的销和箱螺纹之间的松配合允许在螺纹连接的第二段的销和箱螺纹之间的径向和轴向运动，而不会导致螺纹连接的脱离。所公开的混合螺纹连接因此利用多个螺纹段，其中第二螺纹段适应由径向膨胀过程产生的应力和变形，而第一段的螺纹保持螺纹连接的联接强度和压力完整性。
