Description
Technical field
The present invention relates to natural gas well gas production, and in particular to the device that a kind of remote control natural gas well is opened and closed.
Background technology
At present, natural gas is a kind of natural clean energy resource, be widely used in resident's daily life, heating, generating,
Chemicals etc., Substitute coal can be significantly reduced the discharge capacity of CO2, and its demand is increasing.Natural gas is by natural gas
Well, by thousands of meters of the primary gas in underground, is delivered to ground, by pipeline to natural gas processing station, by after purified treatment
End user is delivered to, so the natural gas well is the first procedure of natural gas applications.
Natural gas well equipment is constituted：
The natural gas well protects valve as boundary with emergency cut-off, and the upstream of emergency cut-off protection valve is gases at high pressure pipeline section,
Pressure≤PN25Mpa, downstream is low-pressure gas pipeline section, pressure≤PN6.3Mpa.Manual throttle valve is that the control natural gas well is opened
Open gas production and close the device of gas production.Emergency cut-off protection valve is the safety guard of the natural gas well, when the pressure of its upstream
When power is more than 4.2Mpa, emergency cut-off protection valve will immediately shut off, and protect the safety of low-pressure gas pipeline downstream.Current day
Right gas well opens gas production and closes gas production, is controlled by manually operating the opening and closing of manual throttle.
It is artificial to open natural gas well gas production operating process：
The natural gas well opens gas production, is completed by artificial operation, by constantly adjusting the aperture of manual throttle valve,
The high-pressure gas of gas well are reduced to the low pressure gas of gas pipeline, when gas well high-pressure gas are down to the defeated of technological requirement
During feed channel low pressure gas, the unlatching gas production operation of gas well is completed, the natural gas well is in the normal gas production production phase.Gas well is opened
The whole process for opening must assure that gas pipeline pressure≤4.2Mpa, will otherwise cause emergency cut-off to protect the closing of valve,
Once because misoperation causes emergency cut-off to protect valve closing, gas well to open failure.Ensure that the natural gas well is normally-open, be
The natural gas well opens the biggest problem of gas production, and the experience of operating personnel is completely dependent at present to complete.
The problem that the gas production of current manual control switch's well is present：
The natural gas well can be reduced year by year with the growth of exploitation year, natural gas production, to extend the gas production of the natural gas well
In the life-span, the gas production of the natural gas well is improved, can only be produced using the process of interval gas production, i.e.,：Open natural gas well gas production
After production certain hour, when the reduction of underground natural-gas pressure, gas production reduction, close the natural gas well and stop gas production, treat ground
After lower natural-gas pressure recovers, being then turned on the natural gas well carries out gas production, and constantly reciprocation cycle.
According to statistics, the natural gas well of Soviet Union's Sulige gas field 45% is produced using interval gas producing technology at present, and quantity is also
Increasing year by year.The opening and closing of the natural gas well are carried out using manual site at present, the labour intensity of employee is not only increased,
And be difficult to meet the needs of production.
The opening and closing process of the natural gas well is determined by the experience and ability of operating personnel, the natural gas well is opened and is closed
The failure that the standardization and treatment gas well for closing operation occur is unfavorable.
Natural gas well gas well is in meagrely-populated desert, mountain waste band, road hardships and dangers, field work labour intensity mostly
Greatly, efficiency is low, labour cost is high, there is the risk of the contingencies such as traffic safety higher generation.
When there are the bad weathers such as sleet, dust storm, to ensure personal safety, operating personnel's field condition operation is not allowed,
Directly affect being normally carried out for production.
Repaired or during regulation gas consumption ebb high, it is necessary to be turned on and off hundreds of implication wells simultaneously in airfield equipment, instantaneously
Substantial amounts of operating personnel are needed, usually because of personnel and the deficiency of vehicle, causes to open and close not in time, it is normal that influence is produced
Carry out.
The middle and later periods of natural gas well production life of well, using interval gas producing technology, due to the energy that the natural gas well is opened and closed
Power is not enough, the interval of regulation natural gas well opening and closing time that can only be artificial, it is impossible to according to the actual gas production of the natural gas well
Ability is opened and closed, it is impossible to which make full use of and tap natural gas resource.
