Abstract

Abstract: In view of the exiting problems in the performance prediction for profile control， a new performance
prediction model for multi-layer reservoir profile control is established. Combining profile control mechanism，
an ideal geological model of“multi-oil layers” containing profile control layers and non- profile control layers is
applied to simplify real layers. Firstly， according to the change in plugging rate， the injectivity index of each layers
is evaluated， and water absorption of each layers is calculated on the principle of superposition； secondly， according
to the water flow resistance between oil and injection wells and bottom hole flowing pressure of oil and injection
wells， theplanedistributioncoefficientofdifferentoilwelldirectionsiscalculated， thenthewaterdiversionquantity
of injection well layers is calculated； finally， the separated layer water cut of each oil well is calculated based on the
dynamic development data of oil wells， and eventually the effect of oil well is obtained. Besides， the corresponding
program is compiled according to the relevant theory of the prediction model， and the model is applied to predict
the profile control effect of a real well group.

Key words: profilecontrol, injectivityindex, planedistributioncoefficient, layerwatercut, performanceprediction26
