Detailed description of the invention
The utility model is described in further detail to contrast drawings and embodiments below.
Refer to shown in Fig. 1, the integrated form tree body construction of a kind of subsea production tree, comprise a production tree body 1, production tree body 1 is overall, and in order to have the body of certain wall thickness, central authorities are main pipeline 3, and the upper port of main pipeline 3 and lower port are respectively arranged with metal sealing steel ring, and the lower port place of main pipeline forms Spring Card cotter way 7, hydraulic control spring detent in Spring Card cotter way 7, can clamp metal sealing steel ring, and metal sealing steel ring is pinned.On the main pipeline wall near lower port place, be provided with the test channel 8 that runs through this main pipeline sidewall, preferably, this test channel 8 is axially inclined to set with main pipeline 3 sidewalls.The outer wall of part body forms flange 6, make the wall thickness of the adjacent tube wall of subregion wall ratio of flange 6 correspondences large, the valve passage (41,42,43) running through in the interior setting of this flange 6, described valve passage (41,42,43) is communicated with main pipeline 3, the inside of described valve passage (41,42,43) is provided with and produces valve (21,22,23), and the better system of described production valve (21,22,23) is positioned at the central authorities of each valve passage.On the main pipeline sidewall of production tree body, be provided with the hydraulic channel 9 that runs through main pipeline sidewall, this hydraulic channel 9 is positioned at the step place of production tree body 1 inside at the opening of main pipeline inwall.
Wherein, valve passage 41 is perpendicular to the sidewall of main pipeline 3, and because its valve passage diameter is larger, therefore as main valve passage, its inner production valve of installing 21 is for producing main valve, main valve number of channels can be set to more than one.On main pipeline 3 sidewalls, main valve passage is set, is located among this main valve passage 41 and produce main valve 21, exempt producing the two ends of main valve 21 and the sealing of three-way device terminal interface, reduced the possibility of revealing, improved sealing performance.
In this flange of main pipeline 3, also be provided with the valve passage (42,43) that radially or is axially to tilt extension of relative main pipeline 3, described valve passage (42,43) is all communicated with main pipeline 3, intersect the axis of described valve passage (42,43), be positioned at same plane and be preferably, and on this flange and the intersection point place that is positioned at described axis be arranged with a deep gouge 5, this valve passage (42,43) collects and is connected in this deep gouge 5 to the outlet in main pipeline 3 outsides, and this deep gouge 5 is as the external interface of main pipeline 3.By this interface of sealing, can realize the described valve passage of sealing (42,43) simultaneously.
When the projection of the axis of described valve passage (42,43) is intersected and while not being positioned at same plane, on this flange, also can be provided with a larger deep gouge 5 of length, as long as the outlet of two passages (42,43) is all communicated with this deep gouge 5, still can be by establishing a hermetically-sealed construction in this deep gouge 5, and realize the sealing to two valve passages (42,43).
Production tree body 1 of the present utility model is by this interface and other pipeline communications, and interface arranges hermetically-sealed construction.Compared with main valve passage 41, described valve passage (42,43) internal diameter is less, general as producing flutter valve passage; Described flutter valve number of channels can be set to two or more, but all can be by the method for deep gouge is set at all flutter valve passage axis intersection points, realizes unified sealing; The inside of described valve passage (42,43) is separately installed with pumping valve 22, annular space valve 23.The described interface arranging on production tree body, all docks with other seals for pipe joints.Two passages (42,43) share an external interface, thereby have reduced the quantity that needs the interface of sealing, have reduced the possibility of revealing, and have saved equipment cost.
In addition, the top of production tree body is provided with the draw-in groove for card tooth clamping that coordinates tubing hanger assembly connection, and this draw-in groove quantity setting is more than at least two, and preferably, this draw-in groove is set to 3; The top of production tree body is also provided with the cannelure of an assembling support ring.
The function that the integrated form tree body construction of the utility model subsea production tree is integrated produces valve, has improved the sealing performance of production tree structure, and compact conformation, has improved reliability, has reduced the set-up time of production tree, provides cost savings.
Below be only preferred embodiment of the present utility model, anyone makes a little simple change, modifies or is equal to replacement according to content of the present utility model and all falls into protection domain of the present utility model.
