Change；(4) interaction between phase and phase, gas can be separated out from solution or dissolved in a liquid, wax and hydration
Thing will precipitate in a fluid；(5) flow regime is extremely complex, and characteristic parameter is also more than single-phase streaming system, it depend on each phase it
Between relative velocity, fluid behaviour, pipeline structure and flow direction.
Existing main measurement means and there are the problem of it is as follows：(1) separator adds the metering method of flowmeter, this meter
Amount method can accurately measure the yield of producing well under the little operating mode of small tolerance and viscosity, but if tolerance is bigger than normal, liquid
When gas is mixed with road, flowmeter cannot work normally, if oil well output change is bigger, more than the range of flowmeter
When can not work normally；(2) tipping bucket metering method, under suitable operating mode, tipping bucket can accurately measure the yield of producing well,
But if in the case of no gas, bucket will be flooded, it is impossible to work, tipping bucket metering has movable part to work long hours easy production
Raw failure.
