Abstract
The utility model relates to an offshore oil underwater operation system which comprises a control system installed on a drilling ship, a monitoring system arranged underwater, a buoyancy cabin, a water-resisting pipe, a blowout preventer and a tie back stem. The upper end of the water-resisting pipe is connected with the drilling ship. The lower end of the water-resisting pipe is installed on the blowout preventer. The blowout preventer is arranged on the buoyancy cabin. The upper end of the tie back stem is fixed on the lower part of the buoyancy cabin. The buoyancy cabin is an elliptic enclosed metal barrel comprising a plurality of enclosed chambers. A plurality of spiral propellers are respectively arranged above, below and on the periphery of the buoyancy cabin. The monitoring system and the spiral propellers are connected with the control system through cables. The monitoring system is capable of transmitting the condition of underwater operation back to the control system. The spiral propellers are capable of responding to the control signals of the control system and driving the buoyancy cabin from above, below and the periphery so as to enable the buoyancy cabin to incline or rotate, further to adjust the orientation and the inclination angle of the whole underwater operation system.
Description
Technical field
The utility model relates to offshore oil operation field, specifically, relates to a kind of offshore oil underwater work system.
Background technology
Offshore oil circle mainly adopts offshore boring island to exploit the petroleum resources of continental shelf, sea bed at present.Yet the cost of offshore boring island is extremely expensive, and installs and waste time and energy.
Utility model content
The utility model is the solution proposing for above problem, and specifically, the utility model provides a kind of offshore oil underwater work system.
Offshore oil underwater work system of the present utility model comprises: be arranged on the control system on drill ship, underwater surveillance is set, buoyancy compartment, marine riser, preventer and tie back stem, the upper end of marine riser is connected to drill ship, the lower end of marine riser is arranged on preventer, preventer is arranged on buoyancy compartment, and buoyancy compartment bottom is fixed in the upper end of tie back stem; Wherein, described buoyancy compartment is the oval closed metal bucket that comprises several closed in space, and at buoyancy compartment, upper and lower and surrounding is respectively arranged with a plurality of spiral propellers; Surveillance and spiral propeller are connected to control system by cable respectively, this surveillance can send back control system by underwater operation situation, spiral propeller can be in response to the control signal of control system, from upper and lower, surrounding, advance buoyancy compartment, thereby buoyancy compartment tilted or rotate, and then adjusting orientation and the angle of inclination of whole underwater work system.
Accompanying drawing explanation
Now with reference to the exemplary embodiment schematically showing in the accompanying drawings, the utility model is explained in more detail to explanation.In the accompanying drawings:
Fig. 1 illustrates according to the schematic diagram of offshore oil underwater work system of the present utility model;
The specific embodiment
Offshore oil underwater work system of the present utility model comprises: be arranged on the control system 2 on drill ship 1, underwater surveillance 9 is set, buoyancy compartment 5, marine riser 3, preventer 4 and tie back stem 6, buoyancy compartment is used for making whole operating system to be suspended in water, marine riser and tie back stem are for delivery of the resource gathering, and preventer is for when drill bit runs into the high-pressure oil gas on stratum under water, it can be closed rapidly, to prevent that high-pressure oil gas from upwards spraying well head passage.The upper end of marine riser 3 is connected to drill ship 1, the lower end of marine riser 3 is arranged on preventer 4, and preventer 4 is arranged on buoyancy compartment 5, and the upper end of tie back stem 6 is fixed on described buoyancy compartment 5, sea bed is goed deep into 8 times by subsea equipment 7 in its lower end, thereby gathers oil or natural gas under sea bed.Wherein, described buoyancy compartment is the oval closed metal bucket that comprises several closed in space, and at buoyancy compartment, upper and lower and surrounding is respectively arranged with a plurality of spiral propellers 14,15; Surveillance 9 and spiral propeller 14,15 are connected to control system 2 by cable respectively, and this surveillance 9 can send back underwater operation situation control system 2, and for example, whether underwater instrument normally works, and whether has foreign matter around, whether has oil leakage etc.; Described spiral propeller 14,15 can advance buoyancy compartment from upper and lower, surrounding in response to the control signal of the control system 2 on drill ship, thereby buoyancy compartment is tilted or rotate, and then adjusts position and the angle of inclination of whole underwater work system.
