Subsea Completion with Crossover Passage

摘要

A system for producing or injecting fluids through a tubing hanger connected with a tubing string. The system includes a subsea tree with a tree flow passage and a tree annulus flow passage. The system includes a spool assembly separate from the subsea tree that includes a body with a spool longitudinal passage. The spool assembly also includes a spool lateral flow passage extending laterally from the spool longitudinal passage and configured to transfer the fluids to or from the tree flow passage. The spool assembly also includes a spool annulus flow passage in fluid communication with an annulus. The system includes a mating hub connection between the spool assembly and the subsea tree. The mating hub connection includes a connection configured to fluidly connect the spool lateral passage and the tree passage and an annulus connection configured to fluidly connect the spool annulus passage with the tree annulus passage.

1. A system for producing or injecting fluids through a tubing hanger connected with a tubing string, comprising:
a subsea tree comprising a tree flow passage and a tree annulus flow passage; a spool assembly separate from the subsea tree and comprising:
a body comprising a spool longitudinal passage configured to receive and support the tubing hanger, there being an annulus between the tubing string and the body;a spool lateral flow passage extending laterally from the spool longitudinal passage and configured to transfer the fluids to or from the tree flow passage; anda spool annulus flow passage in fluid communication with the annulus; and a mating hub connection between the spool assembly and the subsea tree comprising:
a flow connection configured to fluidly connect the spool lateral flow passage and the tree flow passage; andan annulus flow connection configured to fluidly connect the spool annulus flow passage with the tree annulus flow passage.
