Simulation of multi-component thermal fluid development effect and correlation analysis of influencing factors
Multi-component thermal fluid had been widely used in heavy oil development,but due to their complex oil increasing mechanism,it was difficult to design their injection parameters reasona-bly.Numerical simulation technology was used to analyze the differences in the effects of multi-com-ponent thermal fluid development and steam huff and puff,confirming the mechanism of multi-compo-nent thermal fluid improving oil recovery.At the same time,the influence of multi-component thermal fluid on development under different injection temperature,injection rate,and soaking time conditions was studied.The result showed that there was an optimal numerical range for these injection parame-ters.Further combining the actual production data of on-site multi-component thermal fluid applica-tion wells,the main controlling factors of their development effectiveness were analyzed,and it was found that injection intensity,injection speed,and injection temperature are the main factors affecting the development effectiveness of multi-component thermal fluid.This provides guidance for designing process parameters for multi-component thermal fluid development.
