摘要： A spherical blow out preventer annular seal is provided for sealing around a pipe (16). The blow out preventer includes a housing (12) adapted to be disposed around the pipe (16) and having a generally spherical interior surface (18). A seal body (20) includes a plurality of metallic inserts (22) arranged side by side in an annular pattern and each includes a base portion (24) and a wedge shaped extension (26) having a partially spherical outer surface (28) terminating at a tip end (30). An annular elastomeric body (32) is over-molded on the base portions (24) of the plurality of metallic inserts (22) with the partially spherical outer surface (28) of each of the wedge shaped extensions (26) being supported in engagement with the interior spherical surface (18) of the housing (12). A piston (52) is engaged with the seal body (20) to press the metallic inserts (22) upward and inward against the generally spherical interior surface (18) of the housing (12) so as to come together tangentially around the pipe (16).

摘要： A system and method to determine and adjust positioning of a subsea test tree (“SSTT”) within a blowout preventer (“BOP”), the system including an SSTT, at least one sensing mechanisms to detect the position of one or more BOP rams and a fluted hanger. Once the assembly is deployed, the ram positions are detected and the position of the fluted hanger is adjusted while deployed to accordingly adjust the spacing between the SSTT and the fluted hanger, thereby eliminating the need of a dummy run. Another system and method improves a dummy run by providing a lightweight joint and dummy hanger deployed on a line (e.g., wireline, slickline, etc.). Through the use of a line and the lightweight of the joint and dummy hanger, the dummy run operation is conducted quickly and efficiently.
摘要翻译：一种用于确定和调整防喷器（“BOP”）内的海底测试树（“SSTT”）的定位的系统和方法，所述系统包括SSTT，至少一个感测机构，用于检测一个或多个BOP系列的位置和一个有槽的衣架。一旦组装被部署，就检测到冲头位置，并且在部署时调整有槽衣架的位置，从而相应地调整SSTT和带槽的衣架之间的间距，从而不需要虚拟跑道。另一种系统和方法通过提供部署在线路上的轻质关节和虚拟衣架（例如，电缆，钢丝绳等）来改善虚拟跑步。通过使用线路和轻量化的联合和虚拟衣架，虚拟运行操作快速有效地进行。

摘要： A system and method is provided for a low profile rotating control device (LP-RCD) and its housing mounted on or integral with an annular blowout preventer seal, casing, or other housing. The LP-RCD and LP-RCD housing can fit within a limited space available on drilling rigs. An embodiment allows a LP-RCD to be removably disposed with a LP-RCD housing by rotating a bearing assembly rotating plate. A sealing element may be removably disposed with the LP-RCD bearing assembly by rotating a seal retainer ring. Alternatively, a sealing element may be removably disposed with the LP-RCD bearing assembly with a seal support member threadedly attached with the LP-RCD bearing assembly. The seal support member may be locked in position with a seal locking ring removably attached with threads with the LP-RCD bearing assembly over the seal support member. Spaced apart accumulators may be disposed radially outward of the bearings in the bearing assembly to provide self lubrication to the bearings.
