摘要
为了探索高温高压条件下天然气在塔河稠油中的溶解规律,采用高温高压PVT分析技术,开展了不同温度和压力下塔河稠油溶解天然气实验研究,得出了稠油中天然气溶解度、溶气密度以及溶气黏度与相关影响因素的变化规律,分析了规律变化的内在原因,为塔河油田稠油注天然气开采现场试验提供了理论基础。
In order to explore the dissolving law of natural gas in Tahe heavy oil under high temperature and high pressure, through adopting the high temperature and high pressure PVT barrel analyzing technology, the experimental studies on dissolving natural gas in Tahe heavy oil under different temperatures and pressures were conducted, and the change laws between the natural gas solubility in heavy oil, density of heavy oil dissolving gas, viscosity of heavy oil dissolving gas and related influence factors were obtained, and the internal reasons for the change laws were analyzed, which could provide a theoretical basis for field test of injecting natural gas in Tahe heavy oil oilfield.
