Abstract

DC60 submersible installations for use in offshore oil and / or gas well drilling and production. Respectively, at deep and medium depths consisting of an intermediate station in the form of a buoyant hollow body (16) attached to the seafloor (10) by a tension receiver. At least one hydrocarbon conveying tube extends between the floating bodies (16) and the depths of the seabed. To transfer hydrocarbons from the source to the floating material (16), at least one cable of the protrusion tube (18a-18h) constitutes the pin / tension receiver holding the floating object (16).

Claims (4)

1. An underwater installation for drilling near the shore of a single or multiple hydrocarbon wells in deep sea wells and sufficiently deep water for hydrocarbon production from the seabed, with one or more wells sheathed. A single or multiple casings opened on the seabed Which installation Such includes The central station in the form of a hollow body with buoyancy. Which the body was completely submerged under Water surface And above the seabed at a depth where there is little influence from the waves The hollow body was Positioned over a single or multiple wells: Tensile anchor method for binding of a central body to the seabed over a single or multiple wells.Such anchoring path consists of at least one pipeline. Hydrocarbons that are formed from extension tubes from casings that extend between and are coupled to a single or multiple open casings of a single or multiple wells on the seabed. And hollow hulls for the formation of traction-bearing pathways for hollow bodies and for the transfer of hydrocarbons from the seabed to the hollow hull. Way of holding the legs The pull forms a one-way path for the binding of such a sunken hull to the seabed and a path for the supply of hydrocarbons from the hollow hull to the surface of the water. 2. The underwater installation according to claim 1 continues to include scaffolds on the seabed for single or multiple open casings of a single or multiple wells. 3.Methods for creating an underwater installation for drilling near the shore of a single or multiple hydrocarbon wells in the deep sea. And deep water sufficient for the production of hydrocarbons from Cistern The installation will feature a fully submerged central station in the form of a floating hollow body. Along with the pipe line extending above for the hollow body to convey Such hydrocarbons to the surface of the water The method consists of the steps of a) using a seabed frame. By drilling one or more wells in the seabed to leave the casing B) Submerged hollow bodies under the surface of the water. C) hollows over a single or multiple ponds; d) retention of the body over the pond by means of tethering to the bottom frame. Sea and hollow body e) To form hydrocarbon protrusions from open sheaths of single or multiple wells to hollow hulls; f) Removing the bindings for retrieval of the casing extents. So that the casing will It becomes a tension leg forming a one-way path for the bonding of a hollow body that is submerged to the seabed, and g) removes a single or multiple sump filling to supply hydrocarbons to the overhang. Expand casing pipe cable 4. Procedures as previously set out in claim 3 include the seizure preparation process. In the form of threads on a single or multiple open ends of a single or multiple casings and they are connected to the adjacent ends of the pipe containing the protrusion of the opposing casing pipe. Will be bound to the hollow body
