PT logging instrument is proposed well head after the completion, downloads all data by more than the shaft bottom bosom that weight stick has just touched three meters of position；
2) throttle valve is opened, is released；Draw spray if necessary and pressurizeed by air pipeline auxiliary valve to well head using air compressor machine, is added
Well head main valve must shut off when pressure, wait several hours, then open throttle valve；
3) value and James's test of well head pressure gauge P3, straight pipe pressure gauge P2 and thermometer T1 were recorded every ten minutes
The value of pressure gauge P1 and weir notch water level h on pipeline；
4) after stability of flow, start dynamic flow-pressure test, to the shaft bottom that the weighted rod of PT logging instrument is touched since well head
More than bosom three meters of position, proposes well head after the completion, downloads all data, and PT logging instrument is relay down toward main production
The depth in region, fixed PT logging instrument simultaneously record pressure；
5) after eight hours of flow open flow, close throttle valve, close flow, latter two hour continue record down-hole pressure；
6) three meters of shaft bottom bosom or more is touched up from weighted rod, record static pressure, downloading data；
7) flow is calculated using weir notch liquid level and James's side pressure, examines heat storage capacity using underground dynamic temperature；
8) power output=flow/(production area dynamic pressure-static pressure)；
9) production area depth is determined using pressure-temperature distribution results, carry out the forecast analysis of pressure buildup.
