低渗透油藏黏弹性可动凝胶深部调剖压力预测新模型
A new model for pressure predicting of viscoelastic movable gel deep profile control in low permeability reservoirs
摘要
Abstract
This paper carried out viscoelastic experiments of gel with different concentrations,shear rates and angular velocities,identified the characteristics of the relaxation time changes of the key vis-coelastic parameters,constructed the apparent viscosity model of viscoelastic movable gel considering the dynamic change of the relaxation time,and based on this,established the prediction model of deep profile control pressure of movable gel in low permeability reservoirs.The model was applied to pro-file control measures for low permeability reservoirs in Yushulin Oilfield and model validation was completed.The results showed that the higher the concentration of movable gel,the greater the re-laxation time.When the shear rate exceeded 2 800 s-1,the elastic viscosity dominated,and the vis-cosity increased instead of decreasing.The compliance rate of the new pressure prediction model calcu-lation is over 80%,which improves the accuracy by 30%compared to the calculation results without considering viscoelasticity.This model provides a theoretical basis for guiding the design of profile control schemes and improving the recovery rate of low-permeability reservoirs.关键词
