FIELD: oil and gas production.
SUBSTANCE: temperature of well is measured and actual thermogram is plotted during operation of pump. All typical changes of temperature opposite to perforation intervals are marked on the plotted thermogram. Formations interlayers are chosen. There are determined final temperature of fluid in well above intervals of perforation and also changes of temperature, which are added with each formation and interlayer from a lower layer and interlayer to an upper one. At condition of inflow absence there is plotted a base thermogram for the given well. The base and actual thermograms are compared. Joined yield of the well is evaluated and registered. Also there are determined heat capacity of formations and interlayers, while yields of separate formations and interlayers are determined by a formula.
EFFECT: increased accuracy of evaluating yield for each separate object.
