Silk operating system, can be carried out at the same time the drillng operation of drilling machine and the steel wire operation of wellhead platform, when reducing occupancy drilling machine operation
Between, individual well operation timeliness is improved, has saved individual well operating cost, reduces oil field development cost.
To achieve the above object, the technical solution adopted by the present invention is：A kind of marine drilling platform crossings on different level steel wire is made
Industry system, including derrick, rig floor, drilling well rise pipe, steel wire rise pipe, steel wire preventer, production tree, well drilling blowout prevention device, steel wire
Top sheave, steel wire rope, winch wire, diesel engine and well head chain-wales, derrick are fixedly mounted on rig floor, well head chain-wales and rig floor
Between by drilling well raise pipe and well drilling blowout prevention device connect, cantilever beam upper deck and cantilever beam lower decks are connected on rig floor,
Winch wire, diesel engine are mounted on cantilever beam lower decks, and winch wire is by Diesel Driven, it is characterised in that：The oil recovery
Tree is mounted on the well head chain-wales and has built operation scaffold on production tree periphery, and steel is sequentially connected on production tree top
Silk preventer, steel wire rise pipe, steel wire top sheave, the bottom of the rig floor, which is equipped with, hangs suspension centre, the upper end of the steel wire top sheave
It is connected between portion and suspension centre by lifting rope, the steel wire rope, one end is managed through steel wire top sheave with steel wire rise, steel wire preventer
Connection, the steel wire lower sheave that the other end is passed through on operation scaffold are connected with winch wire.
Further, the operation scaffold is built by high tensile steel tube, highly highly consistent with production tree tree cap.
Staircase is additionally provided between the well head chain-wales and the cantilever beam lower decks.
Compared with prior art, advantageous effect caused by technical scheme is：
1. by choosing suitable eminence suspension centre on rig floor, drilling well-head is successfully avoided, realizes the same of drill drilling operation
When, wellhead platform carries out steel wire operation, realizes three dimensional intersection spatially and temporal while operation.Greatly reduce occupancy
The drilling machine activity duration improves individual well operation timeliness, reduces operating cost.
2. under the conditions of no production platform, system using the present invention can hang phase by more winches and cantilever beam row
Mutually cooperation realizes wide-span hanging.Realize that marine drilling platform intersects steel wire in no top production module well head chain-wales and makees
Industry.
3. using crossings on different level steel wire operation system of the present invention, individual well can save the rig floor duration 3 days, reduce oil field development
Investment cost.
