Description
Technical field
The utility model is related to petroleum drilling and mining equipment technology field, and in particular to a kind of preventer for geotechnical boring is fast
Close device.
Background technology
With the progress of the exploration and development of Unconventional gas, the investigation and prospecting of domestic Unconventional gas is many new
Regional burning hot progress, particularly some hilly countries, such as Guizhou most area.In order to meet geology and geomorphology condition, reduction is surveyed
Cost is visited, it is being preferably selected for non-conventional gas geological prospecting that geology, which is cored and drilled,.
Need to install preventer in drilling process for closing well, patent CN203223200U discloses a kind of oilfield well testing and used
Steel wire preventer switch pump, act on steel wire blowout preventer hydraulic cylinder and make steel wire preventer quick closedown, including gas drive unit and
Energy-storage units；Wherein, the gas drive unit produces gases at high pressure and is supplied to energy-storage units, and is stored by energy-storage units；Institute
The gases at high pressure that energy-storage units discharge storage according to external command are stated, in the drive of high-pressure gas steel wire blowout preventer hydraulic cylinder
Hydraulic oil, so as to make steel wire preventer quick closedown, described oilfield well testing is switched in pump with steel wire preventer, to compress sky
Gas, using hydraulic oil as dynamic medium, makes gas drive compression pump give gas barrier formula accumulator as the power source of gas drive compression pump
Energy reserve is provided.When steel wire preventer needs closing motion, gas barrier formula accumulator will provide powerful liquid in moment
Pressure power gives steel wire preventer, steel wire preventer was completely closed in 30 seconds, so as to meet the requirement of current standard.
But, in the exploration and development of Unconventional gas, geotechnical boring has rig small, convenient removal, and drilling speed is fast etc.
Feature., can only be in excavation well under well head to install preventer but geotechnical boring rig bores card and flushed with ground, but geology brill
Hole drill machine base is I-steel pressure-bearing, limits well head Fang Jing size, does not possess the condition for installing hydraulic blow out preventer, therefore only
Manual preventer can be installed.In drilling, meeting one block of pressure-bearing steel plate of pad, causes the switch of manual preventer not above well head Fang Jing
Just, and in drilling, such as occurs overflow, well head steel plate can not be opened, it is impossible to close preventer.
The content of the invention
The purpose of this utility model is：The problem of for above-mentioned manual preventer switch inconvenience, the utility model is provided
The manual preventer quick closing valve device of geotechnical boring during a kind of Unconventional gas exploitation.
The technical solution adopted in the utility model is as follows：
A kind of preventer quick closing valve device for geotechnical boring, including the blowout preventer body being arranged on well head, it is described anti-
Connecting rod is locked in spray apparatus main body both sides provided with preventer, and the preventer locking connecting rod is provided with quick closing valve apparatus main body, the quick closing valve
Apparatus main body is fixed on preventer locking connecting rod by fixing device, and the quick closing valve apparatus main body is provided with two steel cable grooves, institute
State and dividing plate is provided with the middle of steel cable groove.
The steel cable groove is wound with steel cable, and the winding direction of the steel cable is opposite.
One end of the steel cable is located at well head.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
The termination of the steel cable of two reverse-windings is arranged on well head by the utility model, the control closing well in normal drilling
Steel cable is wrapped in steel cable groove, controls the steel cable driven a well to be in free state.When needing closing well, the steel of lifting control closing well
Rope, then preventer is closed, while driving the steel cable driven a well to be wrapped in steel cable groove.When needing to continue to creep into, what lifting drove a well
Steel cable, then preventer open.The installation cost is low, and manufacture is easy, and the switch of preventer is achieved that using shirtsleeve operation.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model；
Marked in figure：1- blowout preventer bodies, 2- fixing devices, 3- quick closing valves apparatus main body, 4- preventers locking connecting rod, 5- steel

Embodiment
The present invention is elaborated with reference to Fig. 1.
As shown in figure 1, a kind of preventer quick closing valve device for geotechnical boring, including the preventer master being arranged on well head
Connecting rod 4 is locked in body 1, the both sides of blowout preventer body 1 provided with preventer, and the preventer locking connecting rod 4 is provided with quick closing valve device
Main body 3, the quick closing valve apparatus main body 3 is fixed on preventer locking connecting rod 4, the quick closing valve apparatus main body 3 by fixing device 2 and set
Have and be provided with dividing plate 6 in the middle of two steel cable grooves 5, the steel cable groove 5.
The inner cylinder of quick closing valve apparatus main body 3 and preventer locking connecting rod 4 are matched, fixing device 2 ensure quick closing valve apparatus main body 3 with
Preventer locking connecting rod 4 is not subjected to displacement.
Steel cable is wound with the steel cable groove 5, the winding direction of the steel cable is opposite, and a steel cable controls beating for preventer
Open, another steel cable controls the closing of preventer, when opening or preventer, another steel cable automatic winding, convenient next time
Operate
One end of the steel cable is located at well head, convenient to be operated at well head, closes or open preventer at any time
The termination of the steel cable of two reverse-windings is arranged on well head, and in normal drilling, the steel cable of control closing well is wrapped in steel
In grooving, the steel cable driven a well is controlled to be in free state.When needing closing well, lifting controls the steel cable of closing well, then preventer is closed
Close, while driving the steel cable driven a well to be wrapped in steel cable groove.When needing to continue to creep into, the steel cable driven a well is lifted, then preventer
Open.The installation cost is low, and manufacture is easy, and the switch of preventer is achieved that using shirtsleeve operation.
It is embodiment of the present utility model as described above.The utility model is not limited to above-mentioned embodiment, anyone
The structure change made under enlightenment of the present utility model should be learnt, it is every that there is same or like skill with the utility model
