Standardized movable wellhead platform installed by adopting floatover method

The utility model discloses a standardized movable wellhead platform installed by adopting a floatover method. The wellhead platform comprises a topside module and four-leg jacket legs. The topside module comprises a bottom-layer deck, a middle-layer deck and a main deck. The bottom-layer deck, the middle-layer deck and the main deck are sequentially arranged from the bottom to the top. The topside module is in threaded connection with the jacket legs.The standardized movable wellhead platform installed by adopting the floatover method has following beneficial effects: repeated utilization of topside module facilities for oilfield development can be achieved; by flanged joint and an installing method of floatover, time spent on installation at sea is considerably shortened; construction and installation time and investment in engineering facilities are reduced; construction cost and dependence on construction equipment are reduced; cost of oilfield development and risks can be shared; and therefore the standardized movable wellhead platform has a wide application prospect of oilfield development in inland offshore areas.
