Abstract
A separated drilling ship comprises two floating body ships, a drilling module base and a drilling module. A power system, an anchor gear system and a ship navigation system are arranged on each floating body ship. The drilling module base provides structural foundation and is fixedly connected between the two floating body ships. The drilling module comprises a drilling platform and drilling equipment, wherein the drilling platform is arranged on the drilling module base, and the drilling equipment is respectively arranged on the drilling platform and the two floating body ships. The power systems are respectively connected with the ship navigation systems and the drilling equipment. The separated drilling ship solves the problem that the drilling equipment cannot enter and exit freely due to the fact that the drilling equipment needs to pass through rivers in the Caspian sea, overcomes the defect that a powerless platform like a self-elevating drilling platform relies on a tugboat to navigate if the operation positions change in working and further can avoid windstorm work conditions or other severe sea conditions.

The utility model also discloses a kind of embodiment that adopts following drilling ship parameter and adopt technique scheme:
Floating body boat 10: length * wide * height=100.9m * 16.5m * 8m
Floating body boat 20: length * wide * height=100.9m * 16.5m * 8m
Designed draft: 5.5m
Drilling module substructure: length * wide * height=50.0m * 47.4m * 6m
Buoyancy aid A and buoyancy aid B spacing: 30m
Rig floor height: apart from drilling module 6m
In summary, the split drilling ship that the utility model discloses and the manufacture method of split drilling ship, be by building 4 anchor two-shipper r Zweiers of two electric propulsions, relevant drilling well accessory equipment and system are set respectively, building a drilling module pedestal, build a drilling module simultaneously, by this drilling module basis of one of them Ship Transportation, the barging drilling module is arranged, arrive and specify near the marine site, drilling module and two sister ships are linked into an integrated entity, and anchoring begins drilling operation behind the location.After a bite well is finished, can borrow self power propulsion system to navigate by water next drilling area, detachable time two the single ships drilling well task is finished after are by one of them Ship Transportation drilling module basis, select suitable barging drilling module, navigate by water to other marine site by cruiseway.
For this reason, the split drilling ship that discloses of the utility model effect that can reach is:
At first, be split type by drilling ship is designed to, adopt self all-direction propeller and thruster to position also simultaneously and can dispose the anchoring locate mode, thoroughly solved at marine site, the Caspian Sea drill outfit and need cause the similar problem that can not free in and out by river etc.;
Secondly, be by using the split drilling ship to substitute existing unpowered platform, for example: jack-up drilling unit, thereby when having solved jack-up drilling unit and having worked in the waters, if change the drawback that job position just must rely on the tugboat navigation, omitted jack-up drilling unit complex structure and troublesome jacking system, cantilever beam cantilever and mobile system thereof simultaneously.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
