Well Drilling Rig Erection Method

Different weights, different types of Well Drilling Rig construction and installation are different. For example, the Well Drilling Rig, a large-scale Liwan 3-1 gas field, has its lower jacket and upper structure (for production and life) built separately and then lifted by tides on the sea, and the Well Drilling Rig ships to the destination. Land can be towed by tugboats or by means of barges (semi-submerged barges). Nowadays the large ocean Well Drilling Rig is constructed in sections, closed at the slipway (dock), or transported to the sea by large floats. Hang or special methods (such as tidal jacking, etc.) to close. Offshore operations are divided into working conditions. Offshore drilling and oil extraction are required for the displacement of a platform (a platform can usually only be drilled or can only be produced). When the displacement is too large, it cannot be drilled. In fact, the drilling is separated from the mass production of the oil field. Generally, after discovering the possible geological structure of the oil, Well Drilling Rig firstly called an exploration well to determine whether the storage address structure is worth developing. If there is development value, it will continue to be used for drilling. After Well Completion Well Drilling Rig withdrew from the production platform for oil production. The new Well Drilling Rig is equipped with a DP (dynamic positioning) system, which may keep the displacement of the platform from exceeding the limit. Since the production platform will continue to work in the oil field for more than ten years, it may encounter a big storm, so TLP, SPAR is generally used. Jackets, FPSOs, such as fixed or inflexible platforms, prevent disasters.
