The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises that one is arranged on the rig floor 3 of moon pool 2 tops at platform main deck 1 middle part, and rig floor 3 is provided with a derrick 4, and a side of derrick 4 increases the space of half derrick, can carry out drilling tool in drilling operation and connect in advance, the top of derrick 4 is provided with overhead traveling crane 5.
As Fig. 2, shown in Figure 3, arrange on the main deck 1 of moon pool 2 front portions (being the platform bow) that marine riser and marine riser transport equipment 6, arrange on the main deck 1 at moon pool 2 rear portions (being the platform stern) that drill string and drill string transport equipment 7, arrange on the main deck 1 of moon pool 2 one sides (such as the platform larboard) that blowout preventer and blowout preventer transport equipment 8, arrange on the main deck 1 of moon pool 2 opposite sides (such as the platform starboard) that christmas tree and christmas tree transport equipment 9.Corresponding with the four direction all around of moon pool 2, be furnished with respectively at the four direction all around of derrick 4 and be used for cooperating marine riser and marine riser to transport the manipulator 10 that equipment 6 is delivered to marine riser well, be used for cooperating drill string and drill string to transport the pipe machine 11 of carrying that equipment 7 is delivered to drill string well, be used on rig floor 3, discharging the tube drawbench 12 of drill string, be used for cooperating overhead traveling crane 5 tourist bus 13 of drilling tool that hoists, thereby formed marine riser on rig floor 3 tops and entered the district, drill string enters the district, four operating areas in comb district and erecting equipment district can cooperate downwards and operation upwards effectively.Blowout preventer and christmas tree are delivered to well by transporting equipment 8,9 accordingly from rig floor 3 bottoms respectively, blowout preventer enters the district and christmas tree enters two operating areas, district thereby formed in rig floor 3 bottoms, whole like this drilling operation can improve the efficient of drilling operation significantly from the four direction parallel working of rig floor 3.
