Abstract
一种接受提升管并装在近海浮动装置上的悬链线提升管支承管。该支承管与垂直方向成一角度装在该近海浮动装置上,该角度与被安装的悬链线提升管在地磁平静日的自然角度一致。该支承管在沿支承管长度不同点处安装固定到近海浮动装置上,这样,可绕其装设点向浮动装置挠曲,从而使悬链线提升管上的应力为最小。
Description
本发明涉及从海底形成物生产碳氢化合物,具体涉及用于这种生产的提升管。
在从海底形成物生产碳氢化合物时一般并不是在生产过程中所用装置范围的正下方或大致范围内的海底位置处钻若干个井。所生产的碳氢化合物其后通过海底管道输出。其结果是生产和输出提升管在装置与海底之间的提升管中具有一悬链线。浮动生产平台的运动在提升管中引起相应的弯曲和应力。现有技术是通过在提升管中管道部分之间的连接部适当位置处装设球接头来适应提升管的弯曲。球接头的问题在于,与焊接的管道部分相比较为昂贵而较不可靠。
本发明的目的在于解决上述问题。
本发明提供一种可接纳提升管并装在近海浮动装置上的悬链线提升管支承管。该支承管与垂直方向成一角度装在该近海浮动装置上,该角度与被安装的悬链线提升管在地磁平静日的自然角度一致。该支承管在沿支承管长度不同点处安装固定到近海浮动装置上,从而可绕其装设点向浮动装置挠曲。支承管从该浮动装置向外延伸,以使第一装设点位于与支承管下端成一距离处。通过将第二装设点位于与支承管下端进一步成一关键距离处,使支承管获得附加的柔性。支承管可具有一从第一装设点到支承管下端变化的弯曲刚度。
为进一步理解本发明的实质和目的,以下结合附图进行具体描述,图中相同零件采用同一标号,其中:
图1为表示本发明用于一近海浮动装置上的侧剖面示意图。
图2为示意性地表示本发明支承管的一实施例的形状。
在图1中,一近海浮动装置10系通过多根系缆12加以定位。系缆12一端装在浮动装置10上,另一端装在未图示的海底14的锚或桩上。悬链线提升管16从海底14向上并穿过一装在浮动装置10中的中心井18延伸到未图示的生产装置。以支承管20的形式为悬链线提升管提供支承。
支承管20具有一可接纳悬链线提升管16穿过的内径尺寸。支承管20的上端装在浮动装置10上用A表示处,该支承管并与垂直方向成一个与悬链线提升管16在平静海面安装位置的自然角度一致的小的角度。支承管20具有一伸出浮动装置10下端的长度并在用B表示处以及用字母C、D和E表示的预定点处安装固定到浮动装置10的下端。支承管20与浮动装置10之间装设点的数目和位置取决于支承管20所要求的柔性。例如,可通过将装设点C进一步向离开浮动装置10下端处的装设点B移动得到向支承管20下端的较大的柔性。允许支承管20绕其与浮动装置10的各装设点挠曲可使悬链线提升管16上的应力保持在允许范围。
例如通过改变支承管的壁厚和/或直径,可使支承管20从装设点B到其下端具有逐渐增大的柔性。
如图2所示,支承管20可以制成一曲线部分和直线部分的组合,以使该支承管的上端基本垂直并将悬链线提升管沿一基本垂直方向引导到浮动装置的水面上方的一所需位置。在本发明一实施实例中,支承管20的22部为直线状,24部为曲线状,26部为直线状。浮动装置10为180英尺高。支承管的22部为30英尺长,24部为90英尺长,26部为60英尺长。24部具有432英尺的曲率半径,从而在浮动装置10的底部形成一12度的出口角,以与提升管16的自然悬链线相适应。应当理解,图2只是用来表示本发明的一个可能的结构,且未示出支承管20在浮动装置10下面的整个长度。
可采用三种不同方法将提升管16安装在支承管20中。
在预置方法中是在将浮动装置10系在位置上之前将提升管放在海底14上。一旦浮动装置10固定就位,即将提升管16的端部在支承管20的底端定位并穿过支承管拉到一在水面上方的提升管16的端点处。在拉入阶段,提升管16和支承管20的角度假定为不同于自然悬链中性(无弯曲应力)位置的角度。在拉入的开始阶段,角度小于所需中性位置。在拉入阶段结束处,出口角可等于所需中性位置或可大于中性角度。如果出口角大于所需中性位置,一旦提升管16的端部到达表面则提升管需加上附加部分。将现在较长的提升管的上端降低并根据需要加上几段,直至从支承管20出口点处实现所需的平静日中性角度。通过在表面处水平移动浮动装置10,可实现对出口角的另外调节。也可通过一些滔动装置使该装置及所装设的支承管20倾斜,在安装时采用压载物以更精确地调节到支承管的进入点处提升管中性悬链角度。
在现置方法中,未图示的提升管安装船在该安装船在海底设置提升管时接近浮动装置10。通过电缆使提升管16的端部从安装船下降,直至该提升管对于支承管20处于入口点。然后采用一穿过支承管的电缆将提升管16穿过支承管拉到一水面上方的点。然后如上所述完成安装。
在搁置方法中,系通过一穿过支承管20的电缆从提升管安装船对提升管16进行拉动。适当长度的提升管悬吊在提升管安装船与外侧浮动装置10之间以在支承管20的进入点处保持所需的中性入口角。采用这种方法不需要在浮动装置10处的提升管端部增加几段提升管。
本发明不需要昂贵的海底挠性接头和提升管连接装置。采用预置方法可在浮动装置定位后立即安装提升管并可立即使用。这就能尽快开始油、气生产。同时,通常认为全焊管要比带有机械连接装置和挠性接头部件的管道更为可靠。
由于在本发明构思的范围内可以作出许多各种不同的实施例,并由于可以按照本说明书所述的实施例作许多修改变动,因此应理解本说明书的具体描述将被解释为示意性的而并无限制意义。
