Abstract
The utility model discloses an offshore jacket production platform. The jacket production platform is a six-legged jacket production platform or an eight-legged jacket production platform. Jacket legs of the six-legged jacket production platform are arranged into two rows and three columns. Jacket legs of the eight-legged jacket production platform are arranged into two rows and four columns. On the six-legged jacket production platform or the eight-legged jacket production platform, a well slot area is arranged in the area between the jacket legs in the every two adjacent columns, and a plurality of well slots are formed in each well slot area. The jacket production platform can meet the well drilling requirement of more than 40 (not equal to 40) well slots, and the problem that a jacket is eccentric is solved. Through the design of the jacket production platform, the area of a deck is reduced, steel is saved, and project investment cost of the platform is reduced.
Description
Technical field
The utility model relates to a kind of marine jacket production platform.
Background technology
Along with offshore oil and gas field exploration and development is goed deep into, offshore oil platform forward maximizes, intensive, deep water future development, platform upper chunk overall weight also increases thereupon, no matter resource or ability can not meet oil-gas field development demand, the particularly integral installation of ton large module completely of large-scale crane ship (crane barge).Thereby floating tropsch technology can be realized the integral installation of ton large module and make up the inadequate problem of crane barge resource installation large module ability.
Conventional floating holder mounting platform bank is arranged in platform both wings, loads chunk barge and enters ship along jacket operating point is parallel to notch, and the floor space needing strengthens, and steel material is more, causes jacket bias.Conventional floating holder mounting platform is according to the required distance of drill ship, and every wing covers at most 20 mouthfuls of wells, causes both wings to arrange at most 40 mouthfuls of wells.Because both wings arrange that well head shifts to an earlier date pre-drilling well, floating holder begins to rehearse deck while installation need to be temporary fixed, transfers to design elevation after installing again.As shown in Figure 1, barge enters ship to notch chunk is installed along jacket operating point A, B axle are parallel.Its feature bank is arranged in that pre-drilling well is convenient to carry out in platform jacket both sides and later stage drill ship is in place, and jacket installation is waterproof casing at present, and production tree is lower than platform deck of sub-cellar, and platform arranges workover rig.The floor space that wellhead platform is installed in this floating holder to be needed strengthens, and steel material is more, causes jacket bias simultaneously, and every wing covers at most 20 mouthfuls of wells, causes both wings to arrange at most 40 mouthfuls of wells.Production period needs drill ship brill adjustment well in place again, and platform height overall (or deck floor height) is limited to drill ship climb altitude, unless mobilized larger drill ship.
Utility model content
The purpose of this utility model is to provide a kind of marine jacket production platform, 40 mouthfuls of (not containing) above well slots can be set on the utility model production platform, and be provided with platform rig, and upper chunk need to be dragged installation with floating.
The marine jacket production platform of one provided by the utility model, described jacket production platform is six leg jacket production platforms or eight leg jacket production platforms;
The jacket leg of described six leg jacket production platforms is arranged in 2 row 3 and is listed as;
The jacket leg of described eight leg jacket production platforms is arranged in 2 row 4 and is listed as;
On described six leg jacket production platforms or described eight leg jacket production platforms, the region between the jacket leg of adjacent column is provided with well slot district, and described well slot is provided with several well slots in district.
In described marine jacket production platform, described well slot district is located at the region between two row jacket legs, realizes floating and drags platform well slot to be arranged between jacket structure operating point, and the problem that solves platform bias is also saved a large amount of floor spaces.Can the undermost deck that begins to rehearse of normal arrangement, conveniently installation.
In described marine jacket production platform, it is one square that the line between adjacent 4 jacket legs forms.
In described marine jacket production platform, in described well slot district, be provided with 40 above well slots.
In described marine jacket production platform, described jacket production platform is provided with platform rig, be lowered to waterproof casing by described platform rig, cause riser pipe unbraced length to enlarge markedly because adapting to floating holder installation, need carry out part to waterproof casing self and strengthen.
The utlity model has following advantage:
1, the utility model jacket production platform can meet the drilling well demand of 40 mouthfuls of (not containing) above well slots.
2, the utility model jacket production platform has improved the problem of jacket bias;
3, the convenient deck that begins to rehearse that arranges of the design of the utility model jacket production platform;
4, floor space is saved in the design of the utility model jacket production platform, saves steel, reduces the construction investment cost of platform.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing floating holder mounting platform.
Fig. 2 is the result schematic diagram of the utility model jacket production platform.
In figure, each mark is as follows: 1 jacket leg, 2 well slot districts.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 2, the top view of the marine jacket production platform providing for the utility model, this sea jacket production platform is eight leg jacket production platforms, and eight leg jacket legs 1 are wherein arranged in 2 row 4 and are listed as, and A is as shown in FIG. capable, B is capable, 1. row, 2. row, 3. row and 4. row.And the region between the jacket leg 1 of adjacent 1. row and 2. row is provided with well slot district 2, in this well slot district 2, be provided with 60 well slots (be greater than 40 mouthfuls of well slots, do not mark in figure).As shown in Figure 2, this well slot district 2 is located at the region between the capable and capable jacket leg of B of A, realizes floatingly dragging platform well slot to be arranged between jacket structure operating point, and the problem that solves platform bias is also saved a large amount of floor spaces.Can the undermost deck that begins to rehearse of normal arrangement, conveniently installation.
As depicted in figs. 1 and 2, floating holder barge adopts parallel conductive pipe support operating point A, B direction of principal axis to carry out chunk installation.In installation process, rely on tidal level, barge to adjust to carry the lifting of implementing upper chunk with the mode such as elevating mechanism, be aided with special coupling components simultaneously, complete chunk and jacket butt-joint operation.
In the utility model, on jacket production platform, be provided with platform rig (not shown), be lowered to waterproof casing by this platform rig, cause riser pipe unbraced length to enlarge markedly because adapting to floating holder installation, need carry out part to waterproof casing self and strengthen.
Above-mentioned marine jacket production platform, also can be six leg jacket production platforms; Also can be at 2. row conduit leg and 3. row jacket leg or 3. row jacket leg and 4. the region division well slot district between row jacket leg.
