对重质原油注二氧化碳减粘的研究

STUDY OF HEAVY OIL VISCOSITY REDUCTION BY INJECTING CARBON DIOXIDE

用 RUSKA 落球式高压粘度计,测定了一种重质原油在不同温度和不同二氧化碳注气压力下的粘度变化,并建立了描述粘度随温度和二氧化碳注气压力变化的经验关联式。

Viscosity measurements using RUSKA roUingball high pressure viscosimeter have been made on an oil sample with carbon dioxide injected at difference temperature and pressure,An empirical equation has been developed to corr- elate,the experimental viscosity data with temperature and pressure.
