Description
Technical field:
The utility model relates to oil ocean engineering field, particularly relates to a kind of oil marine drilling platform.
Background technology:
China's oil and gas development equipment technology is being introduced, is digesting, absorbing, is being innovated and achieve rapid progress in production domesticization.Offshore oil drilling platform is that drilling equipment bases oneself upon marine basis.From 1970 so far, domestic building together makes mobile drilling platform 53, retired 7, then uses 46.Current China technology in the construction of offshore oil equipment reaches its maturity, and marine drilling platform is the offshore structures being mainly used in drilling well.Platform fills the equipment such as drilling well, power, communication, navigation, and safe life-saving and personnel's living facilities, be that exploratory engineering of off-shore petroleum/gas reservoir develops indispensable means.Mainly be divided into mobile platform and the large class of fixed platform two.Wherein divide by structure and can be divided into: bottom-supported platform, jack-up unit, drill ship, semisubmersible platform, tension leg type platform, the tower platform of guy rope, jacket platform, concrete gravity platform, deep water comply with tower platform.
At present, what domestic and international existing well drilling of shallow sea platform generally adopted is hydraulic lifting mode and the drilling well of well head slot type, and inefficiency, increases operating cost, is not suitable for shallow-water oilfield operation.Simultaneously; current offshore boring island is all generally that deck platform main body directly connects; although this structure is easily manufactured; but shock resistance is poor; when impacting deck when there is falling object from high altitude in the course of the work, usually can cause damage to deck, time serious, even can damage platform; and inconvenience is keeped in repair after damaging in deck, affects the progress of operation on the sea.
Vital effect is played in the development of exploration and development to domestic economy of offshore oil natural gas, but, the self-elevating drilling platform for offshore of domestic production, due to the equipment of its offshore boring island not movement, and complex structure, gravity is larger, therefore all to manufacture in ship business, then discharge water into dock, make it floating, the manufacture of therefore present offshore drilling platform can only utilize seashore or region along the river just can carry out, the place of dried up a little far point is just inconvenient, rationally effective utilization also just can not be carried out in land place away from water bank, result is that the production cycle of self-elevating drilling platform for offshore is lengthened, producing cost increases.
Utility model content:
In order to solve the problem, the utility model provides that a kind of structure is simple, operating efficiency is high and offshore boring island not easily impaired technical scheme:
A kind of oil marine drilling platform, comprise offshore boring island main body, spud leg, shoe, stepping mechanism, lifting mechanism, spud leg adopts bolt to be connected with offshore boring island bottom part body, install vertical hydraulic oil cylinder between shoe and spud leg, lifting mechanism adopts vertical hydraulic oil cylinder to be connected to offshore boring island bottom part body.
As preferably, between vertical hydraulic oil cylinder top and described offshore boring island, brute spring is installed.
As preferably, offshore boring island surface is installed dull and stereotyped, and backing plate is arranged on dull and stereotyped upper surface, is provided with some reinforcing ribs between dull and stereotyped and offshore boring island.
As preferably, stepping mechanism is made up of horizontal hydraulic pressure oil cylinder, trapped orbit, sliding rail
As preferably, be connected on sliding rail bottom lifting mechanism.
As preferably, installation direction adjuster on the oil cylinder seat bottom vertical hydraulic oil cylinder, oil cylinder seat bearing cover is carved with azimuth scale.
The beneficial effects of the utility model are:
(1) the utility model increases brute spring device on traditional offshore boring island, plays the effect of buffering offshore boring island, reduces the spoilage of offshore boring island.
(2) the utility model installs reinforcing rib dull and stereotyped with platform surface, and install backing plate at planar surface, when there being falling object from high altitude, flat board plays cushioning effect, and after damaging, maintenance range is little, and it is convenient to change.
(3) land that is manufactured on of the present utility model can be carried out, without the need to manufacturing at Xia Shuichu.Save cost of production.
Accompanying drawing illustrates:
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, spud leg 2 adopts bolt to be connected with bottom offshore boring island main body 1, vertical hydraulic oil cylinder k is installed between shoe 3 and spud leg 2, some reinforcing rib q are housed between offshore boring island main body 1 and dull and stereotyped m, dull and stereotyped m upper surface is installed backing plate n and is played cushioning effect and reduce dull and stereotyped m and clash into because weight falls and the damage that causes, vertical hydraulic oil cylinder c installs at top one section of crossbeam b, brute spring a is installed between crossbeam b and offshore boring island main body 1 play cushioning effect and protect offshore boring island main body 1, make offshore boring island main body 1 uniform force, direction adjuster d oil cylinder seat e bottom vertical hydraulic oil cylinder c is equipped with, oil cylinder seat e bearing cover is carved with azimuth scale, stepping mechanism is by horizontal hydraulic pressure oil cylinder h, trapped orbit f, sliding rail g forms, lifting mechanism is arranged on sliding rail g, after offshore boring island manufacture completes, when needing mobile offshore boring island, first adjust direction with direction adjuster d, injection liquid force feed in vertical hydraulic oil cylinder c, the rising of vertical hydraulic oil cylinder c drives offshore boring island main body 1 to rise, after offshore boring island main body 1 leaves ground, injection liquid force feed in horizontal hydraulic pressure oil cylinder h, promote slip rail g road at trapped orbit f forward slip, and drive offshore boring island main body 1 to move forward, after arriving horizontal hydraulic pressure oil pole extreme position, vertical hydraulic oil cylinder k injection liquid force feed between spud leg 2 and shoe 3, shoe 3 is stretched out downwards until kiss the earth, trapped orbit f departs from ground under vertical hydraulic oil cylinder c piston driving, and then handle horizontal hydraulic pressure oil cylinder h, horizontal hydraulic pressure oil cylinder h is regained, make trapped orbit f be placed in new position, front and complete overall movement, now to adjustment direction, direction adjuster d can be regulated to regulate the direction of trapped orbit f and sliding rail g, shift action is repeated again until offshore boring island main body 1 moves to launching position after adjustment direction.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
