微泡沫稠油混合流体的消泡特性研究
Defoaming characteristics of microfoam-heavy oil mixed fluid
摘要
Abstract
This study utilized self-made oil-resistant and salt-tolerant water-based foam,combined with image analysis technology,to conduct an in-depth evaluation of the comprehensive performance of four defoamers at the microstructural level of foam.Focusing on the microfoam-heavy oil mixed fluid(foam oil)system and considering the shear between foam and heavy oil interfaces in pipelines,the study explored the effects of defoamer type and addition amount on foam diameter distribution,foam count,and average foam diameter.The results indicate that defoamer H44 presents the shortest defoaming time in both water-based foam and foam oil environments.When the foam volume is lower than 10％(φ),H47 exhibits superior performance.However,when the foam volume exceeds 10％(φ),the defoaming performance of H43 is better than that of H47.When the defoamer dosage ranges from 0.6％-1.4％(φ),a higher addition amount leads to a larger average bubble diameter and a higher defoaming rate.关键词
