Evaluation and simulation prediction method of heterogeneous phase intelligent profile control for reservoir exploitation
摘要
Abstract
Reservoir native heterogeneity and secondary heterogeneity lead to the formation of dominant flow channels in the later stages of development,resulting in complex distribution of remaining oil and difficulties in initiation.Intelligent deep micro-gel flooding can achieve high permeability channel plugging through adsorption and expansion,while differentially reducing the permeability of oil and water phases to achieve efficient flow adjustment.Utilizing the connection element numerical simulation method and taking into account the plugging mechanism of"plugging large channels but not small ones"and the oil displacement mechanism of"plugging water but not oil",a numerical simulation method for intelligent deep micro-gel flooding has been developed.This enables rapid calculation and prediction of oil-water dynamics.On this basis,the evaluation method of heterogeneous profile control effect is established by introducing Lorentz coefficient,which can quantitatively evaluate the reservoir stimulation effect before and after profile control.The application results of the concept example and the actual example show that the heterogeneous intelligent flooding evaluation and simulation prediction method proposed in this paper can quantitatively assess the extent of development improvement,achieve rapid and accurate prediction of heterogeneous intelligent deep gel flooding.It holds practical value for formulating on-site flooding schemes.关键词
