Abstract
The utility model discloses a kind of electrical measurement blowout hookup, it includes the body of tubulose, and the upper end of the body is sequentially provided with open flow killing well joint and upper end box cupling；Multiple hangers are evenly equipped with the circumference of the open flow killing well joint, the side face of the open flow killing well joint is additionally provided with the open flow interface for being connected with kill-job relief line；The upper periphery of the body is fixed with the back-up ring that the support body of annular, lower, outer perimeter are fixed with annular.The utility model is simple in construction, easy to operate; cable, which need not be cut, can implement closing well; it is effectively protected electric logging equipment; the risk of electric logging equipment is lost when greatly reducing overflow; avoid the generation that Electrical Measuring Instrument falls into accident in well simultaneously; the plenty of time of subsequent treatment accident is eliminated, has evaded the risk of major accident.
Description
Technical field
The utility model is related to electrical measurement implement technical field, and in particular to a kind of electrical measurement blowout hookup.
Background technology
Total well known, electrical measurement operation is an essential cargo handling operation in petroleum exploration and development, and electrical measurement operation is general
Need the time longer, due to the Unpredictability of strata pressure, overflow, well kick event happen occasionally during electrical measurement, therefore
Well control work is also that can not at all loosen during electrical measurement operation.When occurring overflow during electrical measurement, in the case of conditions permit,
Electrical Measuring Instrument can be played out rapidly, blowout prevention column is then grabbed, and implement closing well.If overflow rises comparatively fast, have little time electricity
Instrument is surveyed, traditional way is turned off cable, grab blowout prevention column, then implement closing well, or implement direct closing well, such electrical measurement
Instrument is fallen into well, and the construction to next step brings great trouble, if neutron source will cause serious accident.
Utility model content
For the drawbacks described above of prior art, the purpose of this utility model is to provide a kind of electrical measurement blowout hookup, comes true
Protect and occur quickly realize closing well during the complicated phenomenons such as overflow, well kick in electrical measurement operation, and do not need to cut cable.
The technical solution of the utility model is：Body including tubulose, the upper end of the body is sequentially provided with open flow kill-job
Joint and upper end box cupling；Multiple hangers, the side face of the open flow killing well joint are evenly equipped with the circumference of the open flow killing well joint
It is additionally provided with the open flow interface for being connected with kill-job relief line；The upper periphery of the body be fixed with annular support body,
Lower, outer perimeter is fixed with the back-up ring of annular.
Further, the upper end hoop is box box cupling.
Further, the inner of the open flow interface is in the axial direction apart from the box lower end 200mm of box box cupling inner surface.
Further, the open flow interface is pin thread hickey.
Further, the open flow interface external diameter is 2 ".
Further, the body is 7 " sleeve pipes.
Further, the external diameter of the back-up ring is at least 9 ".
The utility model is simple in construction, easy to operate, it is not necessary to which closing well can be implemented by cutting cable, be effectively protected electricity
Measurement equipment, loses the risk of electric logging equipment, while avoiding the hair that Electrical Measuring Instrument falls into accident in well when greatly reducing overflow
It is raw, the plenty of time of subsequent treatment accident is eliminated, has evaded the risk of major accident.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, upper end box cupling, 2, box, 3, open flow killing well joint, 3.1 open flow interfaces, 4, hanger, 5, support body, 6,
Body, 7, back-up ring, 8, lower end body.
Embodiment
Referring to Fig. 1, a kind of electrical measurement blowout hookup, including body 6, body 6 is that 7 " sleeve pipe, the upper end of body is sequentially provided with
Open flow killing well joint 3 and upper end box cupling 1；Multiple hangers 4 are evenly equipped with the circumference of open flow killing well joint 3, open flow killing well joint 3
Side face is additionally provided with the open flow interface 3.1 for being connected with kill-job relief line, and open flow interface 3.1 is that external diameter is 2 " pin thread screw thread
Interface；The upper periphery of body is fixed with the back-up ring 7 that the support body 5 of annular, lower, outer perimeter are fixed with annular.Upper end hoop 1 is
Box box cupling, the inner of open flow interface 3.1 is in the axial direction apart from the box lower end 200mm of box box cupling inner surface.Wherein：Upper end
Box cupling 1 is used to connect the cable packer of electrical measurement；Open flow and kill-job can be achieved away from box lower end about 200mm in open flow interface 3.1
Function；Hanger 4 is distributed on the circumference of open flow killing well joint, convenient lifting.The effect of support body 5 is to allow this blowout hookup to put down
Surely it is placed on turntable surface, has a diameter larger than the latus rectum of rotating disk small bushing；The external diameter of back-up ring 7 at least 9 ", the effect of back-up ring is anti-
Only pressure testing or occur overflow when, borehole pressure is excessive, by blowout hookup eject rotating disk outside.
Main operational principle of the present utility model is：Blowout preventer half is first sealed into flashboard before electrical measurement and is replaced by 13-5/8 "
Flashboard, then tripping in blowout hookup, makes below the flashboard of back-up ring 7 to 13-5/8 ", support body below 5 in well head sit straight 7 " slips,
Cable packer is installed, blowout hookup is fixed in well head, open flow killing well joint 3 connects kill-job by open flow interface 3.1
Relief line, then carries out pressure testing to complete equipment.When occurring overflow implementation closing well, half envelope ram preventer is first closed, then
Cable packer is closed, interior spray and outer spray is effectively controlled, open flow is carried out further according to on-site actual situations and kill-job operation is straight
It is normal to recovery.Cable, which need not be cut, can implement closing well, be effectively protected electric logging equipment, be damaged when greatly reducing overflow
The risk of dead electricity measurement equipment, while avoiding the generation that Electrical Measuring Instrument falls into accident in well, eliminates the big of subsequent treatment accident
The amount time, the risk of major accident is evaded.
