It is an object of the invention to provide a kind of offshore drilling platform open front double-wellhead derrick geometry, to solve two layers
Platform, tube drawbench are located at derrick body interior, and derrick is bulky, and setback capacity is limited, V-type open front insufficient height, influence
The problem of drilling tool movement.
To solve the above problems, the technical solution used in the present invention is：
A kind of offshore drilling platform open front double-wellhead derrick, it include four supporting legs be connected to drilling platforms face base,
Derrick main body, derrick main body includes the driller being made up of drag link and brace to side unit, driller's side unit, head rig side list
First, auxiliary rig side unit, is connected with bolt between each adjacent derrick unit with connecting plate, and the derrick main body is located at main shaft mouthful
Between service shaft mouthful, the driller of derrick main body is provided with quadruple board platform to side unit outside, and tube drawbench, comb are provided with the top of quadruple board platform
The track hypomere of machine is located at below drilling platforms main deck surface, the cantilever frame that the track epimere of tube drawbench overhangs with derrick main body
Frame is connected；The driller opposite with quadruple board platform is open to the side of side unit.
Preferably, the apical side height of the quadruple board platform is located at the bottom of derrick main body, 1/2nd of thribble on quadruple board platform
Below drilling platforms deck plane.
Preferably, closed at the top of the derrick main body at head rig side unit, auxiliary rig side unit and be respectively equipped with one
Overhead traveling crane, is provided with two sets of top drive guide rails on the side wall of derrick main body.
Preferably, driller is close on the base to being provided with drilling tool movement mechanical arm at side unit.
Beneficial effects of the present invention are：
（1）Derrick of the present invention is four supporting leg open front structures, and the shifting of drilling tool is easy in driller's side unit leading flank opening
Fortune；Quadruple board platform and tube drawbench independence and derrick main body, positioned at the outside of derrick main body so that the capacity of quadruple board platform does not receive derrick master
The influence of body, increased the storing capacity of drilling tool, while having saved the inner space of derrick main body, derrick main body section size becomes
It is small, the volume of derrick main body is reduced, reduce the weight of derrick main body；
（2）Derrick main body of the present invention is located in the middle of main shaft mouthful, service shaft mouth, and derrick body top is provided with two overhead traveling cranes, wells
Two sets of top drive guide rails are provided with frame body, are easy to head rig, auxiliary rig coordinative operation, improve operating efficiency；
（3）Quadruple board platform is located at the outside of derrick main body, and the length of thribble 1/2nd is located at below drilling platforms main deck surface, has
Effect reduces the height of quadruple board platform, reduces born wind load.
