摘要:

新疆吐哈葡北油田为一典型的挥发性油藏,是我国首先开展混相驱实验的油田。混相压力是决定该油藏能否实现混相驱的重要依据。为了确定葡北油田注气的最小混相压力(MMP),对地层流体PVT数据进行了模拟后,应用数值模拟方法进行细管模拟研究,计算出多次接触混相的最小混相压力,并用拟三元相图对MMP进行了分析和解释。计算结果与实验室测定的MMP基本吻合,模拟计算和实验结果说明了葡北油田在目前地层条件下能达到混相驱开采。

Abstract:

Pubei oil field in the Tuha basin, Xinjiang is a typical volatile oil reservoir, and it is the first one to be under miscible flooding in China. Whether miscible flooding happens or not in this field depends on the miscibility pressure. In order to determine the minimum miscibility pressure (MMP), PVT tests and slim tube simulation were carried out and the MMP was calculated. In addition, MMP was analyzed and interpreted on the pseudo-ternary phase diagram. Simulation results are in good accordance with those of laboratory measurements. It is concluded that miscible flooding can be realized in this field under the present formation conditions.

Key words: miscible flooding, simulation, minimum miscibility pressure, slim tube test
