摘要：

泡沫油在不同的压力条件下存在气泡不断产生与破灭的过程，因此，其压力-体积-温度（PVT）测试方法与常规原油的PVT测试方法不同，属于非稳态测试。在不同的压力衰竭速度条件下，测试得到的泡沫油PVT物性差别较大，为了准确表征泡沫油在不同操作参数条件下的PVT性质、准确表征在实际油藏生产过程中的PVT特征，需要对泡沫油的PVT关键参数进行实验分析。笔者开展了委内瑞拉超重泡沫油PVT特性系列实验，揭示了泡沫油开采“拟泡点”特性，总结出了一套泡沫油PVT参数的非常规测试方法，实现了泡沫油在非稳态条件下的PVT物性参数的精确测量，并描述了其影响因素。

Abstract:

The PVT test method of foamy oil is different from that of conventional oil because there is a process in foamy oil during which gas bubbles are continuously generated and burst successively under different pressure conditions, therefore, the PVT test of foamy oils is a non-stable test. The measured PVT behaviors of foamy oil are quite variable under different pressure depletion rates. In order to characterize PVT behaviors of foamy oil under different operating parameters and depict PVT behaviors during a real production process of reservoirs, experimental analyses on key PVT parameters of foamy oil were carried out. A series of experiments on PVT behaviors were carried out using a Venezuelan extra-heavy foamy oil sample, which revealed a pseudo bubble point behaviors during foamy oil production, and a set of non-routine tests for PVT parameters of foamy oils was summarized. This approach can achieve accurate measurements on PVT behavior parameters under non-routine conditions and describe their influence factors as well.

Key words: foamy oil, non-routine test, depletion rate, PVT, pseudo-bubble point
