Description
Technical field
The invention belongs to marine deep water well completing test technical field, in particular to a kind of deep water test completion tubular column and set
The method of printing.
Background technology
At present, at home and abroad in marine deepwater drilling and completion, marine deep water well completing test printing and packer setting are normal
It is with technique：Divide tubing string twice, a printing tubing string, a lower packet tubing string.Tubing string causes the activity duration twice due under
It is longer, and deepwater drilling platform somewhat expensive, therefore production cost is very high.Further, since deep water packer setting depth by
Tidal range influence is very big, causes existing packer setting precision also poor.
Above-mentioned discussion content purpose be to reader introduce may be described below and/or advocate it is of the invention each
The various aspects of the related technology of individual aspect, it is believed that the discussion content contributes to as reader with background's information, to be advantageous to more
Understand various aspects of the invention well, it is therefore to be understood that be that these discussions are read with this angle, it is existing without being to recognize that
Technology.
The content of the invention
A kind of deep water test completion tubular column is provided and set it is an object of the invention to avoid deficiency of the prior art
The method of printing, to improve operation timeliness, improve school depth precision.
The purpose of the present invention is achieved through the following technical solutions：
Deep water tests completion tubular column, and the tubing string connects including packer, setting tool assembly, positioning successively from bottom to top
Head, with long string, hanger assembly, be sent into tubing string, the setting tool assembly include setting tool, become buckle joint, it is described fixed
Position joint is that the long string of matching somebody with somebody is used to connect setting tool assembly for confirming to match somebody with somebody long tube column length below hanger assembly
And the drilling tool between hanger assembly, the hanger assembly are used to sit hanging tube post to well head.
Wherein, the tubing string internal diameter meets electrical measurement, the requirement of pitching.
Present invention also offers a kind of using the deep water as described above test completion tubular column method that is set and printed,
Comprise the following steps：
S1：The tubing string is sequentially connected into well, is insertion during tripping in, inside and outside tubing string；
S2：Hanger assembly, which is sat, to be hung to well head, closes preventer group printing flashboard, and electrical measurement school is deep；
S3：According to the setting tool assembly of school depth result upper lifting pipe post, packer to packer set position, pitching is set
Sealed packer is tested, is slipped out of the hand；
S4：Pull out of hole.
The present invention is by integrating conventional deep water well completing test printing and packer setting tubing string in one-trip string, in hanger
Preventer group can be printed after hanging well head while carry out school depth operation by sitting, deep to packer setting according to school depth result upper lifting pipe post
Degree, realizes packer setting.The one-trip string of the present invention can realize that printing preventer group and packer setting test two purposes of envelope,
Save the activity duration.For 500~3000m depth of water well completing test operations, can be improved the field operation time 4 using this method~
10 hours, save operating cost 50~3,000,000 yuan.It can realize that hanger is sat using this tubing string and method to hang to well head, then
School depth operation is carried out, deep water packer setting depth is influenceed smaller by tidal range, it is possible to achieve the accurate school of tubing string is deep, can be in depth
Packer setting precision is improved to 0.3m during water operation.
Brief description of the drawings
Using accompanying drawing, the invention will be further described, but the embodiment in accompanying drawing does not form any limit to the present invention
System, for one of ordinary skill in the art, on the premise of not paying creative work, can also be obtained according to the following drawings
Other accompanying drawings.
Fig. 1 is the schematic diagram that deep water test completion tubular column set printing.
Include in Fig. 1：1 --- packer；2 --- landing nipple；3 --- with long string；4 --- hanger is total
Into；5 --- it is sent into tubing string；6 --- marine riser；7 --- hanger assembly variable buckle；8 --- preventer group；9 --- pit shaft；
