Abstract
The invention discloses a pressure monitoring and relieving device for a closed oil well. The pressure monitoring and relieving device for the closed oil well comprises an upper connecting pipe, a lower connecting pipe, a gate valve, a bolt, a close cover bolt and a connecting cover, the upper end of a substrate is connected with the upper connecting pipe, the lower end is connected with the lower connecting pipe, one side end is connected with a GSM pressure warning device while the other side end is connected with the gate valve, the gate valve is connected with a gate valve close cover, and the upper connecting pipe is connected with a single-hole exhaust valve. The liquid surface in an oil pipe ascends due to water injection, fracture, geological movement and the like formation pressure change of the closed oil well, the gas is discharged through an automatic exhaust valve, when the liquid ascends to the well mouth, the automatic exhaust valve is closed, when the pressure rises to 2 Mpa, the pressure warner works, the GSM warner sends out buzzing for three minutes, a built-in GSM card sends five short messages to a fixed mobile phone number to give an alarm, a manager goes to the site to connect pipelines and open the gate valve to lower the pressure in the oil well after receiving the short messages, and then the manager disassembles the automatic exhaust valve and uses an oil extraction vehicle to extract the liquid; the pollution is avoided, and the hidden danger is lowered; the pressure monitoring and relieving device for the closed oil well is simple in structure, convenient to manufacture and low in cost.
Description
Technical field
The invention belongs to pressure release technical field, be specifically related to one and close down oil well pressure monitoring pressure relief device.
Background technology
The existing oil well of China, tens thousand of mouthfuls of oil wells are wherein about had to be in because the development time is long or production capacity is not enough the state of closing down, the state that the overwhelming majority all adopts well head directly to close, owing to closing down well because of water filling, pressure break, the strata pressures such as geological movement change, cause part to close down OIH atmospheric pressure to increase, the modes such as current employing Oil Well packer, but, because crude oil has suitable corrosiveness, the well head intensity of oil well is reduced, when closing down the limit that well pressure breakthrough well mouthpiece is subject to, well head bursts, the oil gas of high pressure erupts thereupon, cause very large contamination accident, also very large economic loss is brought to enterprise, this type of accident is common space in a newspaper also.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of this invention is to provide one and closing down oil well pressure monitoring pressure relief device, there is Real-Time Monitoring and close down oil well state, and alarm and notify the feature of testing staff.
To achieve these goals, the technical solution used in the present invention is: one closes down oil well pressure monitoring pressure relief device, comprise tube connector, lower tube connector, gate valve, bolt, capping bolt, connection cover, it is characterized in that, pedestal upper end connects upper tube connector, and lower end connects lower tube connector, one side connects GSM pressure warning unit, another side connects gate valve, and gate valve connects gate valve capping, and upper tube connector connects Single Opening Exhaust Valves;
Described GSM pressure warning unit is used for sending 3 minutes chimes of dooms, and sends five note alarms to fixing cell-phone number;
Described Single Opening Exhaust Valves is used for Exhaust Gas, and liquid level reaches well head self-closed.
Described upper tube connector connects Single Opening Exhaust Valves by connection cover.
Described gate valve connects gate valve capping by capping bolt.
Described pedestal is bolted gate valve.
The alarm pressure of described GSM pressure warning unit is 2Mpa.
The invention has the beneficial effects as follows:
1) stopping to be in closed state for a long time because closing down oil well, producing after blowout, the significant pollution accident of appearance.
2) stop because the enterprise after closing down oil well generation blowout produces heavy economic losses
3) effective detecting formation pressure change, for science, efficient oil recovery provide strong foundation.
4) effectively, fast can find accident potential, and remove a hidden danger in time.
5) this apparatus structure is simple, easily manufactured, low cost.
reference numeral
Fig. 1 is structural representation of the present invention.
Wherein, 1 is GSM pressure warning unit; 2 is pedestal; 3 is upper tube connector; 4 is connection cover; 5 is Single Opening Exhaust Valves; 6 is lower tube connector; 7 is bolt; 8 is gate valve; 9 is gate valve capping; 10 is capping bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, one closes down oil well pressure monitoring pressure relief device, comprise tube connector 3, lower tube connector 6, gate valve 8, bolt 7, capping bolt 10, connection cover 4, it is characterized in that, pedestal 2 upper end connects upper tube connector 3, and lower end connects lower tube connector 6, one side connects GSM pressure warning unit 1, another side connects gate valve 8, and gate valve 8 connects gate valve capping 9, and upper tube connector 3 connects Single Opening Exhaust Valves 5;
Described GSM pressure warning unit 1 for sending 3 minutes chimes of dooms, and sends five note alarms to fixing cell-phone number;
Described Single Opening Exhaust Valves 5 is for Exhaust Gas, and liquid level reaches well head self-closed.
Described upper tube connector 3 connects Single Opening Exhaust Valves 5 by connection cover 4.
Described gate valve 8 connects gate valve capping 6 by capping bolt 10.
Described pedestal 2 fixes gate valve 8 by bolt 7.
The alarm pressure of described GSM pressure warning unit 1 is 2Mpa.
Operating principle of the present invention is:
When closing down well because of water filling, pressure break, the strata pressures such as geological movement change, in oil well oil conduit, liquid level rises, gas is discharged by automatic air valve, when liquid rises to pithead position, automatic air valve cuts out, liquid is full of oil pipe, when pressure continues to rise, pressure alarm starts effect, when pressure rises to 2Mpa, GSM alarm sends the buzzer of three minutes, and utilize built-in GSM card to send five notes to fixing cell-phone number to warn, after administrative staff receive note, arrangement personnel are to on-the-spot, connecting pipe, open gate valve, the pressure of oil well is reduced, unload automatic air valve again, with the liquid carried in oily car proposition oil pipe, thus reach the accident potential eliminated and close down well blowout, when this closes down the situation that pressure increase frequently appears in well at short notice, can consider again to exploit this well.
