MODULE OF SATELLITE TREE AND FLOW LINE STRUCTURE FOR INTERCONNECTION OF A SATELLITE WELL TO A SUBSEA PRODUCTION SYSTEM |
摘要 |
A satellite tree module (STM) (10) for controlling flow between a satellite well and a subsea production system includes at the bottom of the STM a connector (12) of an internal-latch, hydraulically operated type. A lower structure (14) consists of a central ring and projecting arms terminating in guide funnels. An upper structure (18) supports a reentry pole (20) integrated to the STM assembly (10) via an orientation key, a reentry mandrel (22) and a cap (24) for protection of the external profile of the reentry mandrel (22) and its receptacles. A flow system is arranged above the lower structure (14) and inside the upper structure (18). The flow system consists of a set of pipes and valves through which production/injection, production testing and lift-gas fluids flow. A flow line terminal (26) and a control system responsible for the activation of the STM (10) components during the operational phase are amounted to one of the upper and lower structures.
