Abstract:
一种具有采油树（107、207）和井口（103）的水下油井组件。油管从油管悬挂器（113）延伸到油井中。产油流动通道的一部分从所述油管悬挂器（113）竖直地延伸到所述采油树的竖直孔（111）中。失灵自动关闭式的生产主阀（PMV）（117）被布置在所述产油流动通道中。所述油管悬挂器（113）被布置在所述采油树（107）的下方，例如被布置在所述井口（103）中。所述采油树（107）呈现有从所述竖直孔（111）分出的支路（115），所述支路构成所述产油流动通道的一部分。所述失灵自动关闭式的生产主阀（PMV）（117）被布置在所述支路（115）中。
Abstract(English):

Subsea well assembly having a Xmas tree (107, 207) and wellhead (103). From a tubing hanger (113) a tubing extends into the well. A part of a production flow passage extends vertically from the tubing hanger (113) in a vertical bore (111) of the Xmas tree. A fail close production master valve (PMV) (117) is arranged in the production flow passage. The tubing hanger (113) is arranged below the Xmas tree (107), such as in the wellhead (103). The Xmas tree (107) exhibits a branch (115) that deviates from the vertical bore (111), which branch constitutes part of the production flow passage. The fail close type production master valve (PMV) (117) is arranged in the branch (115).
