Description
Technical field
The utility model relates to engineering the drilling engineering device technique field, in particular to a kind of fields water injection that do not pull out of hole is filled with aperture
It sets.
Background technique
It needs to do packer permeability test to drilling before slip casting currently, drilling is administered on coal mine floor, the leakage to check borehole
Size determines slip casting discharge capacity.
The opening arrangement used in doing aperture packer permeability test in the past, it is necessary to drilling tool in hole be proposed outside hole, seriously shadow
Ring engineering construction progress.Accordingly, it is desirable to provide a kind of hole for not needing to propose drilling tool in hole outside hole in the packer permeability test of aperture
Mouth device.
Utility model content
The technical problem to be solved by the present invention is to provide one kind not to need in the packer permeability test of aperture by drilling tool in hole
It is proposed the fields water injection opening arrangement that do not pull out of hole outside hole.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of do not pull out of hole fields water injection opening arrangement, including crossover sub and ontology, the crossover sub top is equipped with
Female connector, the lower part of the crossover sub are equipped with fillet of tool joint pins, and the body lower part is equipped with casing, is equipped on the ontology
Pressure gauge and note hose coupling are equipped with Water filling valve on the note hose coupling, and the crossover sub and ontology pass through flange
Connection.
Preferably, described sleeve pipe is connected using pin thread with well inner sleeve.
Preferably, the flange includes upper flange and lower flange, is respectively set to son on the inside of the upper flange and lower flange
Female mouth is nested.
Preferably, it is fixed between the upper flange and lower flange outside using screw.
By adopting the above technical scheme, (1) can not have to proposing drilling tool in hole into the situation outside hole using the utility model
Lower carry out packer permeability test, and working efficiency can be effectively improved by pressure data information in the timely acquisition pores of pressure gauge, it reduces
The labor intensity of worker；It (2) can be same by the top of note hose coupling and crossover sub using the device of the utility model
When filled the water into well, greatly improve water-injection efficiency.

In figure, 1- crossover sub, 2- ontology, 3- female connector, 4- fillet of tool joint pins, 5- casing, 6- pressure gauge, 7- water injection pipe
Connector, 8- Water filling valve, 9- upper flange, 10- lower flange.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, Figure 2 and Figure 3, a kind of do not pull out of hole fields water injection opening arrangement, including crossover sub 1 and ontology 2,
1 top of crossover sub is equipped with female connector 3, and the female connector 3 can be connected with external pump, the lower part of the crossover sub 1
Equipped with fillet of tool joint pins 4, the fillet of tool joint pins 4 can be connected with drilling rod in hole, and 2 lower part of ontology is equipped with casing 5, the set
Pipe 5 can be connected with well inner sleeve, and described sleeve pipe 5 can be selected but be not limited to pin thread to be connected with well inner sleeve, and pressure is equipped on ontology 2
Power table 6 and note hose coupling 7 are equipped with Water filling valve 8 on the note hose coupling 7, for controlling the note hose coupling 7
By flanged joint, the flange includes upper flange 9 and lower flange 10, the upper method for opening and closing, the crossover sub 1 and ontology 2
It is respectively set to mother-son mouth on the inside of orchid 9 and lower flange 10 to be nested, the upper flange 9 and lower flange can be selected between 10 outside
But it is not limited to screw mutually to fix, under the premise of making to be screwed and can guaranteeing effective fixed effect, so that structure is simpler
Just, cost is reduced.
In use, by drilling tool lift-off bottom hole, kelly is dismantled before packer permeability test, by the sheet of the device of the utility model
2 sets of body drilling rod in well, and be connected with well inner sleeve, by the top of the crossover sub 1 of the device of the utility model with it is external
After water pump is completely embedded, the lower part of crossover sub 1 is connected with drilling rod in well, makes the upper flange 9 of crossover sub 1 and ontology 2
Lower flange 10 docks, and is fastened with screw, completes installation steps, external pressure pipe is connected with the note hose coupling 7,
It opens outer water pump and the Water filling valve 8 is filled the water, the pressure data out of described 6 acquisition pores of pressure gauge.
Packer permeability test can be carried out in the case where not having to and proposing drilling tool in hole outside hole using the utility model, and can led to
Pressure data information in the timely acquisition pores of excess pressure table 6, effectively improves working efficiency, reduces the labor intensity of worker；Make
It can be filled the water, be greatly promoted into well simultaneously by the top of note hose coupling 7 and crossover sub 1 with the device of the utility model
Water-injection efficiency.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
