煤油稀释(密度计)法测定泡沫稠油密度

Using Kerosene Dilution (Densimeter) Method to Determine Foam Heavy Oil Density

塔河油田存在大量泡沫稠油。实验室测定泡沫稠油密度存在着消泡困难,预处理油温高,时间长,轻质成分损失的问题。通过研究发现煤油对泡沫稠油存在着较好的溶解性、降粘性和消泡性。混合过程服从体积加和性规则。由此研究建立的新方法能够克服单纯密度计法的缺点,对测定泡沫稠油的密度具有较好的适用性。

Taha oilfield has a large amount of foam heavy oil. There are many problem existed in the determination of the density of foam heavy oil in laboratory such as difficult elimination of bubbles, high temperature, long time and losing of light components of oil in preliminary treatment. The study results show that kerosene has a good solubility, viscosity breaking and defoaming for rome heavy oil. The mixing process follows the volume additivity law. Based on the study, the new method can overcome the defect of densimeter method, and this method is applicable to determine the density of foam heavy oil.
