油气储层混合润湿体系研究进展

Research Progress in Mixed-wet System of Oil and Gas Reservoirs

在多孔介质多相流领域中,润湿性是影响流体分布与流动的主要因素之一,油气储层真实润湿性为混合润湿状态这一观点越来越被广大学者所认可。本文对混合润湿体系的基本分类、两相流规律实验以及理论研究中的部分主要研究成果进行分类讨论与分析,总结了目前混合润湿体系研究中所存在的问题,最后对混合润湿体系的发展趋势进行展望,以便对国内混合润湿体系的研究起到参考意义。

Wettability is one of the main factors affecting the distribution and flow of fluids in porous media multiphase flow. Wettability of oil and gas reservoir is mixed that has been accepted by more and more scholars. So partial major developments of the primary classifications, two-phase flow experiments and theoretical researches of mixed-wet system are classifily discussed and analyzed, the existing problems with study of mixed-wet system are summarized. In the end, future development trends of mixed-wet system are outlooked. This work can provide some references for domestic research on mixed-wet system.
