Description
Technical field
The present invention relates to Casing running technology field more particularly to a kind of drilling machine Casing running technology methods.
Background technique
In THE WESTERN SOUTH CHINA SEA sea area with the development of oil-gas field development technology, section petrol resources exploitation step into one it is completely new
Developing stage, along with the promotion of equipment and development ability, the existing disconnection of Partial Jobs operational procedure, unhook problem, if after
Continuous constructing according to original program simply, or existing technological development advantage is caused to lose meaning, it is mentioned compared to the present invention
A kind of excellent fast setting of casing method of module drilling machine supplied, there are many drawbacks, specific manifestations for previous setting of casing working method are as follows: usually
There are three types of modes for drill ship and marine fixed drilling rig drilling well casing job:
1) conventional setting of casing mode: using crane hanging sleeve pipe it is single to rig floor greatly behind the door, using rig floor it is pneumatic/hydraulic wireline winch
Cooperation fastens tourist bus elevator, and tourist bus uplink is opened top drive lower valve turn on pump in decentralization and carried out to casing to casing is transferred after buckling
Fill or the casing of next segment length after, turntable surface sit the static grouting of slips；
2) complicated down-hole casing mode: being aided with continuous grouting tool connector, and it is single to brill to hang 2~3 casings using crane
Platform gate connects single joint elevator in casing elevator decentralization hanging steel rope, lifts make-up after casing using single joint elevator, casing is helped
After positive platform personnel on casing centering to detaining, tourist bus is transferred, opens single joint elevator, fastens casing elevator, using continuous while upper button
Grouting Casing running technology is in the milk to casing using upper button gap；
3) the double pneumatic winches of drill ship are aided with crane Casing running technology method, use crane to hang top sheave as guiding, make
Elevator is directly fastened with closing casing with rig floor pneumatic winch and pipe deck pneumatic winch, and tourist bus uplink after buckling to transferring
Casing, while decentralization while open top drive lower valve turn on pump casing is filled or the casing of next segment length after, turntable surface sit slips
Static grouting.
Field operation proves, these three common setting of casing modes, in module drilling machine batch drillng operation casing job
In all there is great limitation and risk, be not suitable for module drilling machine batch drillng operation, to module drilling machine batch drilling well make
Industry setting of casing mode, complicated in particular for extended reach well, ultradeep well, casing programme, the exceptional wells such as Open-Hole Section, horizontal segment length are outstanding
There are drawbacks for it
1, conventional setting of casing mode:
1) crane hangs sending buckle and closes elevator time and effort consuming, and individual well setting of casing is time-consuming, and crane and operating personnel occupy more, casing
Tripping in time-consuming is longer, and the bigger setting of casing timeliness of underground work risk is lower, average 10~12/h of 13-3/8 〞 casing, 9-5/8 〞
Casing 13~14/h, 7 15~17/h of 〞 tail pipe；
2) static grouting way, down-hole casing string quiescent time is long, glues card dangerous；
3) the following grouting way in side is driven due to top and protects connector distance sleeve elevator height higher, and is pushed up drive protection and connect
Head, sometimes when wind speed very high operation often unsatisfactory with the centering of casing coupling center causes grouting discharge capacity limited, set
Pipe string lowering velocity is limited or can not fill bunch tube at all, and it is also very high that down-hole casing string glues card risk；
4) extended reach well when vertical depth is shallow, naked eye segment length, hole deviation is big, hole condition is poor or hoisting power is limited is trapped
Pipe, is often limited to hook weigh, complex situations not in place under casing occurs, and making original difficulty, just very big extended reach well is made
Industry is more complicated.
2, complicated down-hole casing mode:
1) derrick need to design the related auxiliary facility such as sleeve centralizer, stabbing board camera, increase module drilling machine and build, tie up
Shield and use cost；
2) single joint elevator being hung under casing elevator and playing casing, when playing casing to rig floor, casing stability is bad, hangs there are single
Card connecting steel wire ropes such as scratch at all multi-risk Systems；
3) it needs a people to open single joint elevator in sleeve centralizer during setting of casing, righting is detained on casing and fastens Casing elevator
Card, last every casing commander driller transfer insertion grouting tool pipeline, and cumbersome, step is more, and maloperation risk is larger,
Driller is operated during entire setting of casing it is more demanding, driller need to pay close attention to simultaneously drilling well gate, sleeve centralizer, drilling floor surface and
Drilling instrument etc. easily leads to driller's operation fatigue, causes complex situations to take place frequently so as to cause to the fault of underground situation accurate judgement
Occur；
If 4) quadruple board platform casing centering personnel casing centering is not in place, upper button is bad to plus effect, easily leads to set pipe thread damage
Bad, upper button efficiency is impacted larger, and the casing for replacing damage is affected to timeliness, and entire operation timeliness is undesirable, setting of casing
Timeliness is slightly improved compared with the first, average 13~15/h of 13-3/8 〞 casing, 16~17/h of 9-5/8 〞 casing, 7 〞 tail pipes 18
~20/h；

1) this method setting of casing is equally higher to equipment requirement, need to arrange a pneumatic strand in pipe stockyard deck area
Vehicle, the pneumatic winch face rig floor gate roll two sides casing to pneumatic winch when setting of casing, use crane as
Top sheave hanging point is pulled using rig floor pneumatic winch, the pneumatic winch righting of pipe stockyard deck and safety rope operation, to equipment and
Site requirements is high；
2) there are more limitations for the setting of casing method, and casing discharge region is closer with rig floor relative position, and rig floor pneumatically twists
Vehicle operation amplitude is little, and drill ship rig floor and pipe stockyard deck keep relatively fixed and relatively close, meets this requirement, well slot distribution
More such as 5*8 (2.208*2.208) module drilling machine, the limit arrange well location, limit column well location, and rig floor gate and pipe stockyard deck are arranged
Area under control span is big, and gradient is big, and casing job can not be carried out under the state；
3) rig floor pneumatic winch manipulator cooperates most important with pipe stockyard deck pneumatic winch manipulator, needs true at any time
It is on duty to protect two people；
4) pneumatic winch wirerope operation take up space it is larger, during casing is hung to rig floor from pipe stockyard deck risk compared with
Greatly；
5) because of the presence of guiding crane, pipe stockyard deck space range is occupied, crane in addition can not also carry out down
Crane resources are caused to waste by the related lifting operation that one-shot job prepares.
Above-mentioned problem can be effectively overcome using this technology innovation, improved and trapped in module drilling machine batch drillng operation
Pipe timeliness reduces down-hole casing and glues card risk, optimizes setting of casing risk factor, the use of especially long hanging ring, for big displacement
Well long open hole section, auxiliary use continuous grouting system, increase the success rate of setting of casing in place.
1) under normal circumstances, casing elevator can be fastened by the direct swing arm of elevator, set is fastened and above mentioned using casing elevator
Pipe gap uses continuous grouting system pipeline, is in the milk by valve regulated to bunch tube；
2) for extended type hanging ring when elevator fastens, horn mouth is driven on top has the space 2m or more away from cannula carrier box cupling, completely
Have a possibility of the continuous grouting connector of installation, when setting of casing, the connector hose part inner cylinder length adjustment that will can continuously be in the milk to away from
From 5~10cm of casing coupling, side thus may be implemented and trap tube edge grouting, and do not driven protection connector and casing coupling by top
The influence of centering factor and live wind speed, can be in the milk with biggish discharge capacity, can largely be reduced when being in the milk static
Between；
3) setting of casing is hampered, and when needing to connect hydraulic circulating head, long hanging ring has enough spaces to connect hydraulic circulating head toward undershoot；
4) tube top of trapping, which drives hook weigh, can not push down-hole casing string, when not selecting to connect hydraulic circulating head, can quickly transfer
Top is driven, and wt part is driven on top by continuous grouting tool connector or total weight is applied on bunch tube, bunch tube is pushed to
Shaft bottom.
