Description
Technical field
The utility model belongs to oil/gas well dynamic negative-pressure perforating job technical field, more particularly to a kind of multifunction combined
Hole making drill.
Background technique
Hole making drill is hit by caber, it can be achieved that oil pipe as the important devices in dynamic negative-pressure TCP combined well testing
Connection between internal and annular space guarantees smoothly rising out for oil pipe, prevents " emitting spray to propose " phenomenon, the generation of Prevention of blowout phenomenon.
However inventors have found that existing hole making drill usually only allows while (hitting aperture or pressure drilling two using a kind of aperture mode
It selects one), and is unable to complete the online work for surveying pressure.If two kinds of hole making drills to be arranged simultaneously and increase pressure measuring tie-in, it is bound to
It needs additionally to configure multiple crossover subs, and will increase the length of tool string and increase the intensity of integration of operation, be unfavorable for
Improve the working efficiency of underbalance perforating testing combination operation.
Utility model content
The utility model provides a kind of multifunction combined hole making drill, which has connection just

In order to solve the above technical problems, the utility model adopts the technical scheme that
Multifunction combined hole making drill, comprising:
The hole making drill main structure formed by top connection, the fixed concatenation of lower contact；
The sliding cylinder being slidably arranged in hole making drill main structure internal chamber, is equipped with ring between sliding cylinder and lower contact
Shape pressurizing chamber；
It is additionally provided with prefabricated relief hole and positioning ring in hole making drill main structure, cutting pin is installed in positioning ring；
And be screwed and be mounted on the pressure measuring tie-in of lower contact periphery, pressure gauge is installed on pressure measuring tie-in.
Preferably, pressure gauge periphery is additionally provided with the casing for playing a protective role.
It is selectable, fixation is established by holding screw between top connection and lower contact and concatenates relationship.
It is more preferred, sealing ring is additionally provided between sliding cylinder and hole making drill main structure internal chamber.
Selectable, the quantity for the cutting pin installed in positioning ring is not less than 2.
The utility model provides a kind of multifunction combined hole making drill, which has is connect from above
Head, sliding cylinder, annular pressurizing chamber, prefabricated relief hole, positioning ring, is cut at the fixed hole making drill main structure for concatenating formation of lower contact
The structural units such as disconnected pin, pressure measuring tie-in, casing, pressure gauge.Multifunction combined hole making drill with above structure feature,
With aperture and pressurization two kinds of orifice patterns of aperture are hit, aperture is high-efficient, highly reliable, and can complete to survey pressure behaviour online
Make, it is convenient using simply connecting.
Detailed description of the invention

Appended drawing reference: 1, positioning ring；2, top connection；3, sliding cylinder；4, lower contact；5, pressure measuring tie-in；6, casing；7, pressure
Meter；8, pin is cut off；9, prefabricated relief hole；10, annular pressurizing chamber.
Specific embodiment
The utility model provides a kind of multifunction combined hole making drill, which has connection just
The features such as prompt, multiple functional, compact-sized reliable.
As shown in Figure 1, the multifunction combined hole making drill includes hole making drill main structure, the wherein hole making drill main body knot
Structure is formed by top connection, the fixed concatenation of lower contact.It is more preferred, further pass through holding screw between top connection and lower contact
Establish fixed concatenation relationship.The sliding cylinder that can slide up and down is provided in hole making drill main structure internal chamber, sliding cylinder is under
One annular pressurizing chamber is installed in the space between connector.As the utility model one kind more preferred embodiment, for into
One step improves the sealing effect of hole making drill main structure internal chamber, between sliding cylinder and hole making drill main structure internal chamber
It is additionally provided with sealing ring.
In addition, as shown in Figure 1, being additionally provided with prefabricated relief hole and positioning ring in hole making drill main structure；Wherein, it positions
Cutting pin (generally preferably design has at least two to cut off pin) is installed in ring.The installation and lower contact periphery is also screwed
There is pressure measuring tie-in, pressure gauge is installed on pressure measuring tie-in, which surveys pressure for playing the role of；It is more preferred, pressure gauge
Periphery be additionally provided with the casing for playing a protective role.
Fig. 1 carries out one to the working method of logger pressure equaliser provided by the utility model with reference to the accompanying drawing
Lower description.During equipment is gone into the well, sliding cylinder and sealing ring cover prefabricated relief hole in hole making drill main structure, oil pipe with
Casing pressure is mutually isolated；Then artificially control well cylinder pressure forms negative pressure and imitates so that wellbore pressure is less than bottom pressure
Fruit.It when tap operation, is introduced in pressure drilling mode as an example, is suppressed from well head first, so that oily liquid in pipe
Entered in annular pressurizing chamber by sliding cylinder (or the hole opened up on sliding cylinder)；The pressure effect generated in annular pressurizing chamber
On sliding cylinder, so that sliding cylinder is mobile to top connection direction；Then when pressure reaches or beyond the cutting installed in positioning ring
When the shearing force of pin, cutting pin is cut off, and sliding cylinder, which continues up, exposes prefabricated relief hole, realizes that oil pipe and annular space connect
It is logical.And impacting type aperture then can be described as: cutting pin be severed using the shock stick cast from well head, so that liquid in annular space
Sliding cylinder (or the hole opened up on sliding cylinder) is flowed by positioning ring and is entered in annular pressurizing chamber；Then annular adds
The pressure generated in pressure chamber acts on sliding cylinder, so that sliding cylinder is mobile to top connection direction, exposes prefabricated relief hole, realizes
Oil pipe is connected to annular space.
The utility model provides a kind of multifunction combined hole making drill, which has is connect from above
Head, sliding cylinder, annular pressurizing chamber, prefabricated relief hole, positioning ring, is cut at the fixed hole making drill main structure for concatenating formation of lower contact
The structural units such as disconnected pin, pressure measuring tie-in, casing, pressure gauge.Multifunction combined hole making drill with above structure feature,
With aperture and pressurization two kinds of orifice patterns of aperture are hit, aperture is high-efficient, highly reliable, and can complete to survey pressure behaviour online
Make, it is convenient using simply connecting.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
