Major label description in figure:
1 main platform body, 2 spud legs, 3 oil storage chambers, 4 hydraulicefficiency elevation structures, 5 crude oil production treatment facilities, 6 crude oil exporting equipment, 7 suction pile bases, 8 are advanced, oil exit pipe, 9 inlet pipe, drain pipe, 10 sea level, 11 seabeds.
The specific embodiment
As shown in Figure 1-Figure 3, the present invention includes: elevating platform main body 1, crude oil production treatment facility 5, crude oil exporting equipment 6, living facilities and several various productions and living facilities such as hydraulicefficiency elevation structure 4 are installed on the main platform body 1, are equipped with on the hydraulicefficiency elevation structure 4 and are located at spud leg 2 in the slide guide hole; Can make the main platform body 1 can be by hydraulicefficiency elevation structure 4 along spud leg 2 free liftings to adapt to the job requirements in different depth of waters oil field.The bottom of spud leg 2 adopts welding manner that one oil storage chamber 3 is installed, and oil storage chamber 3 adopts double-decker, adopts ramp structure around the upper surface of oil storage chamber 3.Can effectively reduce the seawater scouring effect, avoid occurring washing in a pan empty phenomenon.
Adopt welding manner that 2 or 4 suction type pile foundations 7 are installed on the oil storage chamber 3.2 or 4 suction type pile foundations 7 run through oil storage chamber 3 respectively and adopt welding manner to be installed on the oil storage chamber 3, but receipts are installed and are removed in the self-operation of its implementation platform, and guarantee the job stabilization of platform.
Operating principle: as shown in Figure 4, after portable production platform arrives the operation on the sea scene, at first, utilize elevating mechanism 4 to put down spud leg 2, the bottom oil storage chamber 3 that is installed in spud leg 2 sinks to 11 mud face places, seabed, suction pile basis 7 on the oil storage chamber 3 pours into seabed mud face and forms air-proof condition, the switch of opening submersible pump on the suction pile basis 7 draws water, with exclusive of the water in the suction pile basis 7, make the interior negative pressure that forms of staving on suction pile basis 7, rely on the inside and outside surperficial pressure reduction of staving, staving is pressed into the seabed desired depth.Simultaneously, also oil storage chamber 3 is fixed on the seabed.Then, according to the job requirements in different depth of waters oil field, by the hydraulicefficiency elevation structure 4 that is arranged on main platform body 1, make main platform body 1 can along spud leg 2 free liftings to the sea level appropriate location more than 10, just can carry out production operation.After production operation finishes, utilize lifting elevating mechanism 4 that production platform main body 1 is dropped to the water surface, then, spud leg 2 is risen, and the bottom oil storage chamber 3 of spud leg 2 is packed up, and be fixed on the bottom of portable production platform.At this moment, can move boat and sail for the elsewhere.Bottom oil storage chamber 3 behind the empty cabin can also provide buoyancy for portable production platform in the towage process.
Utilization of the present invention is installed on the main platform body 1 crude oil production facility, to carry out processing from the crude oil that well head is exploited up, and adopt crude oil after crude oil transportation by lighter pump will be handled by be injected into oil storage chamber 3 storages of platform bottom through the advancing of spud leg 2 inside, oil exit pipe 8 and the pouring orifice that is positioned at oil storage chamber 3 inside upper part; Simultaneously, the seawater that utilizes ballast pump will be positioned at oil storage chamber 3 bottoms is discharged outboard by inlet pipe, drain pipe 9 suction inlets of oil storage chamber 3 side lower parts by the inlet pipe, drain pipe 9 through spud leg 2 inside, finishes the oil and water displacement process of oil storage, oil extraction.
During crude oil exporting, by Cargo Oil Pump and oil exit pipe with the crude oil exporting in the oil storage chamber 3 to alongside regularly in the Tanker-Transport of platform, and seawater is pressed into oil storage chamber 3 from oil storage chamber 3 side lower parts by ballast pump and water inlet pipe, finish the oil and water displacement process of oil extraction.
Advantage of the present invention is:
1. reduced the cost of winning in single oil field;
2. realize the marine oil extraction pattern of honeybee formula in a plurality of oil fields of platform development, greatly reduced the cost of winning of a plurality of marginal oil fields;
3. utilize oil storage chamber oil storage under water to satisfy the needs of platform oil storage, saved cost of production;
