Method for fixing underwater production manifold in steel cylinder below seabed mud surface through fixing pins
The invention discloses a method for fixing an underwater production manifold in a steel cylinder below a seabed mud surface through fixing pins. The method for fixing the underwater production manifold in the steel cylinder below the seabed mud surface through the fixing pins comprises the following steps: construction of a bearing foundation of the underwater production manifold is carried out; reserved holes are formed; the production manifold is placed into water and is in place; a mounting hole of the fixing pin is chiseled; a fixing pin is mounted; and other steps are carried out. According to the method for fixing the underwater production manifold in the steel cylinder below the seabed mud surface through the fixing pins, after the underwater production manifold is in place, the holes are formed in the concrete foundation bearing the underwater production manifold, the fixing pins are installed on the concrete foundation, so that the underwater production manifold can be fixed to the concrete foundation, and therefore the method is not limited by the in-place position of the underwater production manifold. The method for fixing the underwater production manifold in the steel cylinder below the seabed mud surface through the fixing pins disclosed by the invention is convenient to construct and low in manufacturing cost, can meet the fixing requirement of the underwater production manifold in the steel cylinder below the seabed mud surface, is an economical and efficient fixing method, is suitable for fixing the production manifold in the underwater steel cylinder in a navigable area, and has a wide application prospect in oil and gas development engineering in the navigable area of the Bohai Sea.
本发明公开了一种位于海床泥面下钢圆筒内水下生产管汇的固定销固定方法，包括：水下生产管汇的承载基础施工；设置预留孔；生产管汇入水与就位；凿设固定销的安装孔；以及安装固定销等步骤。本发明公开的固定销固定方法，在水下生产管汇就位后，在承载水下生产管汇的砼基础上开孔并安装固定销，能够将水下生产管汇固定在砼基础上，因而不受水下生产管汇就位位置的限制。本发明公开的方法，施工方便、造价低廉，可以满足位于海床泥面下钢圆筒内水下生产管汇的固定要求，是既经济又高效的固定方法，适用于通航区水下钢圆筒内生产管汇的固定，在渤海通航区域内的油气开发工程中具有广阔的应用前景。
