Abstract
The utility model discloses a shallow water tremie frame platform. The tremie frame platform comprises two tremie frames, a horizontal supporting framework and a block, wherein the two tremie frames are relatively arranged and are mutually connected via the horizontal supporting framework; the horizontal supporting framework is arranged at the bottom ends of the two tremie frames; and the block is arranged above the two tremie frames. The shallow water platform provided by the utility model can bear a larger upper block to perform production work and is widely applied to shallow water marine oil development, and a new development mode is provided for the development of marginal oil fields.
Description
Technical field
The utility model relates to a kind of shallow water jacket platform.
Background technology
The As China's oil resources consumption increases considerably, and the national energy strategy receives very big challenge, develops China's offshore oil resource cost-effectively fast and receives much concern.China's marine petroleum development is except that proceeding big-and-middle-sized oil-gas field development, also in the exploitation of actively carrying out the coastal waters marginal oil field at present.Along with continuing to increase of shallow sea petroleum resources exploitation dynamics, used large ocean works is also more and more.Because the extremely shallow restriction of the depth of water, large-scale floating crane can't enter into this shallow water area again and carry out operation.Therefore, the easy novel shallow water platform series of research facilities is extremely urgent, satisfying under the existing construction boats and ships resource situation, implements the middle-size and small-size Oilfield developing in shallow water marine site faster and betterly.
The utility model content
The purpose of the utility model provides the shallow water jacket platform that a kind of facility is simple, be fit to the floating holder installation in Very Shallow Water marine site.
A kind of shallow water jacket platform that the utility model provides comprises two jackets, horizontal support framework and chunk; Said two jackets are for being oppositely arranged; Said two jackets are connected through said horizontal support framework; Said horizontal support framework is located at the bottom of said two jackets; Said chunk is located on said two jackets.
In the above-mentioned shallow water jacket platform, said two jackets are four leg jackets.
In the above-mentioned shallow water jacket platform; Said horizontal support framework is located on 4 leg posts of said two jacket opposite sides; Carry out lifting operation with crane barge, said horizontal support framework can guarantee that two said four leg jackets are in same horizontal level, and the floating holder that helps said chunk is installed.
In the above-mentioned shallow water jacket platform, fixing between said horizontal support framework and said two jackets for welding.
In the above-mentioned shallow water jacket platform, the material of said horizontal support framework is a shaped steel.
Distance between axles between said two 4 leg jackets in the above-mentioned shallow water jacket platform is decided by the employed barge of floating holder, and employed barge needs to decide according to the weight and marine site, the place depth of water of said chunk.
Chunk on the shallow water jacket platform that the utility model provides is heavier; Consider the influence of shallow water and boats and ships resource, can consider to use the mode of ballast to float holder, the active force when LMU (butt joint buffer) need being installed on said two jackets cushioning said chunk butt joint; Perhaps adopt 4-8 cover pulling force jack that chunk is installed; The pulling force jack is installed on the pillar of said chunk, after floating holder finishes, can the pulling force jack be removed.
The utility model has the following advantages owing to adopt above technical scheme:
1, two jacket structures can bear bigger chunk weight, have enough strength and stiffness;
2, can implement floating holder operation in the Very Shallow Water marine site;
3, two jackets can separately be built, and are welded to connect at last, save the duration;
4, this device adopts the conventional structure form, and operating principle is simple, and is easy to process.
In sum, the shallow water platform series of the utility model can bear bigger upper chunk and carry out production operation, applies to widely among the shallow water marine petroleum development, for the exploitation of marginal oil field provides a kind of new development mode.

Each mark is following among the figure: 1 four leg jackets, 2 upper end horizontal support frameworks, 3 lower end horizontal support frameworks, 4 ropes, 5 barges, 6 chunks.
The specific embodiment
Below in conjunction with embodiment the utility model is further specified, but the utility model is not limited to following examples.
The shallow water jacket platform that the utility model provides comprises two four leg jackets 1, lower end horizontal support framework 3 and chunk 6; Two four leg jackets 1 link into an integrated entity through lower end horizontal support framework 3; Lower end horizontal support framework 3 is weldingly fixed on four leg posts that are oppositely arranged of two four leg jackets 1; The material of lower end horizontal support framework 3 is a shaped steel, enables to bear in the hoisting process active force of two jackets 1 to it; Lower end horizontal support framework 3 is fixed in the bottom of two jackets 1, and when in the waters, locating, this lower end horizontal support framework 3 should approach the seabed; Chunk 6 is located on two jackets 1, is used to bear functions such as field produces operation, life.
In the above-mentioned shallow water jacket platform, lower end horizontal support framework 3 also can be the overall space frame construction of other material that rigidity and intensity should be enough strong; Lower end horizontal support framework 3 also can be connected with two jackets 1 through alternate manner, like mechanical connection; Horizontal support framework 2 and 3 length depend on two 4 distances between the leg jacket 1, and the distance between 4 leg jackets 1 depends on employed floating holder boats and ships resource (being the size of barge 5); The employed barge 5 of floating holder is relevant closely with the weight of upper chunk 6; Upper chunk 6 is heavy more, and employed barge 5 will be big more; The selection of barge 5 also need be considered the residing marine site of the shallow water jacket platform depth of water; Because the depth of water is more shallow, large ship can't get into this marine site, and the above upper end horizontal support framework 2 of the water surface gets final product more than in general being positioned at water surface 1m-1.5m.
Above-mentioned shallow water jacket platform can be installed according to following method: at first; The upper end of two jackets 1 (promptly being positioned at the above part of the water surface) connects through upper end horizontal support framework 2; Lower end (promptly being positioned at the part at mud face place) connects through lower end horizontal support framework 3; Upper end horizontal support framework 2 and lower end horizontal support framework 3 all directly are welded on 4 leg posts of inside of two jackets 1, can utilize crane and 4 integral hoistings of lifting rope in place, as shown in Figure 2; The above upper end horizontal support framework 2 of the excision water surface is as shown in Figure 3 after in place; As shown in Figure 4, for being positioned at, chunk 6 floats the sketch map of holder during operation on the barge 5, and after butt joint finished, barge 5 withdrawed from jacket 1, welding chunk 6 and stake, then the shallow water jacket platform is in place in the operation area, and is as shown in Figure 1; In the above-mentioned installation process, be in different positions when the hoisted in position, and adopt horizontal support framework 2 to be connected, make jacket 1 when in place, can keep same horizontal plane with 3 for avoiding two ductule framves 1; After jacket 1 is in place, adopt the mode of piling that jacket 1 is fixed on the operation area,, help barge 5 floating holder operations, and the lower end horizontal support at mud face place can not excise then with 2 excisions of the upper end horizontal support framework more than the water surface.
