Example two:

firstly, connecting a liquid inlet hose 55 of a full-analysis oil sample sampler of a high-water-content oil well with a sampling gate on a wellhead flow, turning on a power switch, pressing a start button, starting operation of an upper-row fan 25S and a lower-row fan 25X, and starting timing; secondly, a sampling gate is opened, oil well output liquid enters a liquid inlet hose 55 and enters a separator 43 through a liquid inlet electromagnetic valve 54 and an on-valve pipeline, air in the separator 43 passes through an exhaust electromagnetic valve 6 and flows to an automatic ignition windproof gas furnace 8 through a flow-limiting air nozzle and a gas pipe 5, an air-water interface in a liquid level detection meter 9 ascends synchronously along with the ascending of the liquid level in the separator 43, and after the air-water interface reaches an uppermost IV liquid level switch, a signal reaches a PLC (programmable logic controller) and a set program is started. The controller PLC closes the exhaust electromagnetic valve 6, and the pressure in the separator 43 gradually rises to be consistent with the wellhead back pressure. The oil well output fluid entering the separator 43 is differentiated under the action of gravity to form a pure gas zone, a foam zone, a pure oil zone and a pure water zone from top to bottom. The upper part in the detection body is a pure gas area, and the lower part is a pure water area. After the set time is reached, the controller PLC closes the liquid inlet electromagnetic valve 54, opens the sewage discharge electromagnetic valve 47 and opens the exhaust electromagnetic valve 6, and sewage is discharged into the sewage bucket 60; the gas is discharged, enters the automatic ignition windproof gas furnace 8 and is combusted; when the air-water interface is separated from the level III switch, a signal is generated to the controller PLC, the set program is started again, the sewage discharge electromagnetic valve 47 is closed, the liquid inlet electromagnetic valve 54 is opened, and the oil well output liquid enters the separator 43 again in a large amount. And circulating the steps, and performing the next action by the controller PLC after the set time is reached. If the next signal is sent by the IV liquid level switch, the PLC directly controls the liquid inlet electromagnetic valve 54 to be closed, the sewage discharge electromagnetic valve 47 is opened after the set time is reached, sewage and a small amount of oil enter the sewage bucket 60, and the liquid level is lowered until the III liquid level switch sends a signal. If the next signal is sent by the level III switch, the controller PLC controls the sewage discharge electromagnetic valve 47 to be closed. The dc motor 36 is started to stir, the oil in the separator 43 is further degassed and dehydrated, and the dc motor 36 stops operating after a set time. The controller PLC controls the sewage discharge electromagnetic valve 47 to open for water discharge, and sewage and partial degassing oil enter the sewage bucket 60. After the gas-water interface is reduced to the II-th liquid level switch, the controller PLC controls the sewage discharge electromagnetic valve 47 to be closed, the sampling electromagnetic valve 17 to be opened and the bottom water electromagnetic valve 18 to be closed, and the degassed crude oil flows into the oil sample barrel 28. After the set time is reached, the controller PLC controls the sampling electromagnetic valve 17 to be closed, the blow-down electromagnetic valve 52 to be opened, and redundant degassed crude oil is discharged; after the set time is reached, the bottom water electromagnetic valve 18 is opened to flush residual oil in the separator 43 by using bottom water; after the set time is reached, the blowdown electromagnetic valve 52 is closed, and meanwhile, the sound-light alarm 7 gives an alarm to prompt that the sampling is finished; thirdly, pressing a stop button, stopping the operation of the upper exhaust fan 25S and the lower exhaust fan 25X, closing a power switch, closing a sampling gate, opening the manual blowoff valve 22 to drain residual oil and water, cleaning the site and finishing sampling operation.

Note that: the height of the liquid inlet hose 55 of the high water content oil well total analysis oil sample sampler is higher than the gate of the well mouth back pressure gauge, and the automatic ignition wind-proof gas furnace 8 is arranged at the lower air inlet and outside the well field.
