FIELD: oil production industry, particularly to control multizone reservoir development in which reservoirs are developed simultaneously. ^ SUBSTANCE: method involves taking samples from key wells for which intervals depths are associated with sea level; measuring oil paramagnetism signals, which are concerned with content of four-valence vanadium and free stable radicals in above samples to obtain V and R characteristics correspondingly; obtaining base values of V and R characteristics for each sample; relating thereof with corresponding key wells; determining values of theta=V/R characteristic, which are typical for developed reservoir; determining expected value of controlling characteristics for each reservoir in well to be investigated by using one characteristic of V and R ones as controlling characteristic; taking oil samples from well head during control performing and checking that the oil sample is received from the developed reservoir by comparing value of theta characteristic with typical characteristics of above reservoir; eliminating influence of another reservoir on the developed one if above influence is detected; turning over well investigations beginning from taking samples from head thereof and comparing thereof with expected value and determining oil recovering reservoir or estimating content of oil received from particular reservoir in total oil influx to investigated well. ^ EFFECT: increased control efficiency, reliability and informativity and reduced labor inputs for production reservoir determination. ^ 1 tbl, 1 ex |
