Abstract
The invention discloses a kind of cementing cement head column assemble method, comprise the following steps：Offline pre-terminated cementing head and short drill pipe first at deck, form cementing head A combinations；Secondly drilling rod plug is installed offline using assembly pulley method at deck；Then well logging deck is hung on from deck by 3 drilling rods and cementing head, top, which is driven, coordinates cat road machine that two drilling rods are moved into upper rig floor, connects two drilling rods in well head, links closely to form B combinations, sit slips；Top, which is driven, coordinates cat road machine that cementing head A combinations are moved into upper rig floor from well logging deck, combines connection with well head B and links closely, forms complete cementing cement head column；Connection well cementation pipeline and cementing head, well cementation pipeline is bundled in cementing head column correct position, cementing head bearing is supported；The cementing head column bound finally is stood on into rig floor, completes well cementation preparation.By the method for the present invention, well head holding time can be reduced 60 minutes, reduce lifting operation number 2 times, there is good application effect.
Description
Technical field
The present invention relates to offshore oil to be drilled well field, and in particular to a kind of cementing cement head column assemble method.
Background technology
The deep water sea areas such as the Gulf of Mexico, West Africa, the South Sea, which contain, largely abundant petroleum resources, and deepwater drilling operation is
Develop guide's engineering of subterranean oil gas reservoir.When drill bit reach it is a certain open time finishing drilling depth after, carry out it is next open time drilling before, need
Tripping in sleeve pipe is wanted to carry out well cementing operation, the assembling process of cementing cement head column is indispensable.In marine oil and gas drilling engineering,
Cementing cement head column is typically according to top-down order：Short drill pipe++ two drilling rods of cementing head body.In well cementing process,
Top short drill pipe connects top and driven, and cementing head body is responsible for the drive of connection top, underground and well cementation pipeline.Cementing slurry passes through well cementing pipe
Line enters interior tubing string and in sleeve pipe, displacement fluid flows through top drive and interior tubing string replaces cement mortar into annular space, is finally completed well cementing operation.
Because taking day for marine oil and gas drilling well especially deep-sea oil gas drillng operation is higher, per hour up to hundreds thousand of members,
The built-up time of existing cementing cement head column is generally 2 hours or so, has certain compression stroke.The phase is assembled in cementing head
Between, lifting operation three times need to be undergone, the depth of water super 1000m in marine site residing for deepwater drilling platform, sea situation is severe, and stormy waves stream situation is answered
It is miscellaneous.If in lifting operation process, drilling platforms occur it is complicated heave, it is vertical/horizontal shake, institute's hoisting thing and ground control personnel are equal
Larger health and safety risk will be faced.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned prior art, there is provided a kind of cementing cement head simple to operate is stood
Post assemble method, well head holding time and lifting operation number in installation process can be reduced, cementing cement head is rapidly completed and stands
The installation of post.
To achieve these goals, the technical solution adopted by the present invention is：A kind of cementing cement head column assemble method, its
It is characterised by：Comprise the following steps：S1:Offline pre-terminated cementing head and short drill pipe at deck, cementing head A combinations are formed, it is selected short
Drilling rod need to meet to require with long；S2:Drilling rod plug is installed offline using assembly pulley method at deck；S3:From deck by 3 drilling rods
Well logging deck is hung on cementing head, top, which is driven, coordinates cat road machine that two drilling rods are moved into upper rig floor, connects two drilling rods in well head, links closely
B combinations are formed, sit slips, waits and combines connection with cementing head A in next step；S4:Top drive coordinate cat road machine by cementing head A combine from
Upper rig floor is moved on well logging deck, combines connection with well head B and links closely, forms complete cementing cement head column；S5:Connection well cementation pipeline
With cementing head, well cementation pipeline is bundled in cementing head column correct position, cementing head bearing is supported；S6:It will bind
Cementing head column stand on rig floor, complete well cementation preparation.
The beneficial effects of the invention are as follows：The present invention can reduce well head holding time and lifting operation in installation process
Number, the installation of cementing cement head column is rapidly completed, reduces production operation expense.Marine drilling platform etc., which can be suitable for, to be had
The drilling well scene of Gao Fei features, it also is adapted in the higher scene of lifting operation risk, there is good application effect.
Brief description of the drawings
The present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram for installing drilling rod plug in the present invention using assembly pulley method.
Embodiment
A kind of cementing cement head column assemble method of the present invention, comprises the following steps：
S1:Offline pre-terminated cementing head and short drill pipe at deck, form cementing head A combinations, and selected short drill pipe need to meet to require with long；
The step need not take uphole time.
S2:Drilling rod plug is installed offline using assembly pulley method at deck；As shown in Figure 1.Installed by using assembly pulley
Method Quick labor-saving, it is only necessary to 1 people, and it is not take up uphole time.
S3:Well logging deck is hung on from deck by 3 drilling rods and cementing head, two drilling rods are moved and bored by top drive cooperation cat road machine
Platform, two drilling rods are connected in well head, link closely to form B combinations, sit slips, wait and combine connection with cementing head A in next step.Actual behaviour
When making, uphole time shared by the step is 20 minutes.
S4:Top, which is driven, coordinates cat road machine that cementing head A combinations are moved into upper rig floor from well logging deck, combines connection with well head B and links closely,
Form complete cementing cement head column.During practical operation, uphole time shared by the step is 10 minutes.
S5:Connection well cementation pipeline and cementing head, well cementation pipeline is bundled in cementing head column correct position, to cementing head axle
Hold and be supported.During practical operation, uphole time shared by the step is 15 minutes.
S6:The cementing head column bound is stood on into rig floor, completes well cementation preparation.During practical operation, the step institute
Uphole time is accounted for as 5 minutes.
The installation of cementing cement head column is carried out using the method for the present invention, total uphole time that takes is 50 minutes；And adopt
2 hours or so are then needed with traditional method；Using the installation method of the present invention, efficiency significantly improves.
Above content is merely illustrative of the technical solution of the present invention, technology of the one of ordinary skill in the art to the present invention
The simple modification or equivalent substitution that scheme is carried out, all without departing from the spirit and scope of technical solution of the present invention.
