Mouth pipeline tail end connects the manual relief valve of 50mm.
It is made up of gas port, the decorative pearl on top of an official cap, spring, baffle ring, nut, pressure relief opening thread protector set inside described automatic decompression valve, gas port
Upper end is airtight by the decorative pearl on top of an official cap, withstands connecting spring, and spring is fixed in baffle ring to be fixed by nut, in the up and down interval of the decorative pearl on top of an official cap
Automatic decompression valve outer wall be provided with pressure relief opening.
The beneficial effects of the utility model are：
Low pressure well head pressure control recovers the oil test, test effect significantly, improves pump efficiency and volume increase, shortens the oil recovery time, reach
Energy-saving Expected Results.I.e. staff labor intensity reduces, and energy efficiency effect substantially, has and automatically controls well head row pressure,
It is not required to want artificial real-time operation, reduce person works' amount, preferably carry out negative pressure production, process is simple, cheap, operation side
Just simple advantage.

11 is fixing, and automatic decompression valve 3 outer wall in the up and down interval of the decorative pearl on top of an official cap 8 is provided with pressure relief opening.
Embodiment
On-the-spot test, count, analyze 9 mouthfuls of wells, and the geological conditions for different wells and production status optimization tool
The oil recovery air pressure hold in range of body.Detailed operation amount is shown in Table 1.
Build the pressure DP technology technology through multiple improvement and perfect well head, in " three low wells ", there is very big production
Advantage, implements well, all obtains good volume increase, improves the effect of pump efficiency.
Apply as shown in Figure 3,
As：Loose 583 wells, field observation, before the improvement that do not build the pressure, 1 hour 50 points of upper liquid, upper liquid 1 hour
Oil pumping mode：Stop 21 and take out 3
After building the pressure：Air pressure 0.08Mpa. 3-7 minute upper liquid, 25 minutes upper liquid time
Oil pumping be adjusted to stop 23 take out 1 hence it is evident that improve pump efficiency
According to test of many times：
Air pressure exists：Between 0.06-0.08-0.15MPa, upper liquid is normal, and dash is big
Air pressure exists：Between 0.01-0.03, upper liquid is slow, and dash is little, and upper liquid measure flow velocity is slow
Air pressure between 0.4-0.7MPa, not upper liquid.
Measurement of power figure：Gas lock, gases affect are shown in sight.
Nanniwan oil recovery factory using 125 mouthfuls, is contrasted by Field Production Data and finds in two groups of recovering the oil, low pressure well head
Pressure control oil recovery test, effect is significant of having a try, improve pump efficiency and volume increase, shorten the oil recovery time and slow down stratum energy release, reach
Energy-saving Expected Results.Only economize on electricity one reaches 23.1 ten thousand yuan in 2015.
Operation principle of the present utility model is：
After pressure control, in oil recovery process, the flow rate of liquid in oil pipe is made to become big, standing valve is opened, and pumps at short notice
Mouth forms pressure, increases producing pressure differential, thus reaching the purpose improving pump efficiency.
Through a large amount of test of early stage and calculating, find, when oil recovery air pressure is maintained in certain limit, to improve pump efficiency and reach
Most preferably.In well head, the device that builds the pressure is installed, oil recovery air pressure is maintained in the range of 0.08-0.15, device brings into operation.When air pressure mistake
High or too low, adjust automatic discharging pressure valve, first unclamp fixed screw, air pressure is too high to be adjusted clockwise；Too low to counterclockwise
Direction rotates, and observes air gauge and is advisable with reaching critical field.
