Saturating non-average and oil saturation, this causes fluid when being flowed under strata pressure drives from stratum toward well wellbore,
The flowing velocities of different profile position upper fluids is different, oil mining for a period of time after, infiltration always occurs on production profile
Section where the high interval of rate and the low fluid of viscosity is easier to produce liquid, is commonly angled relative to for the higher oil of water (or gas) viscosity this
It is part bad thing, because water (or gas) can run much faster than oil, the well recovery later stage aqueous (gas) can be because of part well section

, restraining factors all be present in control production liquid.For density correlation technique, on condition that the density contrast of oil and water, this difference exists
Within 0.3kg/L, therefore validity will not be very high, and for viscous crude (density>0.82kg/L) effect is then even more limited；And for
Viscosity correlation technique, then water-bearing crude oil and gassiness thin oil are only applicable to substantially, it is small or even there is viscosity to be less than for profit differences in viscosity
The thin oil of water viscosity, viscosity correlation technique are then helpless.The also existing another question of these equipment, i.e., each equipment room phase
It is mutually independent, do not coordinated, thus it is difficult to the target for reaching full production profile optimal production.
Other a kind of intelligent oil extraction technology is then to be transferred to ground by cable (or optical cable) with the complete monitoring information in underground
Face data processing centre, central station analysis calculate backward down-hole switch equipment and send instruction, down-hole switch equipment
Power (the electricity or hydraulic pressure) controlled valve provided using ground installation, liquid is adopted so as to optimize.This kind of technology is disadvantageous in that
First, analysis calculates facility and power source all on ground, underground facility is only responsible for performing switch order, ground and underground facility
