| 摘 要： | 膨胀试验作为单井吞吐工艺试验的重要评价手段之一,在油田注气混相与非混相驱试验中已得到应用。目前对不同种类气体注入对原油相态影响国内外虽作了些分析和研究,但针对同一种流体究竟那种注入气体较好,还研究得不多。首先对CO2注入时原油膨胀试验和未注气时的常规PVT数据进行模拟后,对CO2、N2、CH4和烟道气四种不同的注入气体进行了模拟研究,给出了在不同种类气体注入时原油的膨胀系数和泡点压力的影响,同时对混合气体的注入进行了分析。分析了各种气体在单井吞吐试验对地层流体的适应性,对其优缺点也进行了对比分析。

| Abstract: | Expansion test, as an important screening tool, is applied widely in miscible flooding and CO2well stimulation. The influ-ences of injection gas on physical behaviors of crude were report-ed in the literatures in petroleum industry. Unfortunately, a few reports on the screening for the injection gas were publicized in the past decades. In this paper, PVT tests were carried outto investigate the influences of such injection gases as CO2, N2 and CH4on expansion factor and bubble point. The results from PVT tests indicated that CO2is the most favorable injection gas for well stimulation in Jiangsu oilfield. |
