Selection Method for Subsea X-tree

摘要

Subsea production system has been widely used in deep-water oil and gas field development.Subsea Christmas tree(X-tree) is the key equipment used to control the flow of oil and gas to or from a well.First of all,the paper gives a summarization of the subsea X-tree design parameters since the configuration of subsea X-tree must be based on design parameters.And then, the advantages and limitations of the vertical and horizontal subsea X-tree are discussed, and in the meanwhile, the selection principle of the subsea tree layout is presented.Finally, characteristics and applicability of the components and the control systems of the subsea X-tree are analyzed.
