摘要:

塔河油田是我国发现的第一个超深超稠碳酸盐岩油藏,埋深5350~6600m,80%的储量为特超稠油,开发极其困难。从稠油的粘度影响因素出发,以塔河油田近10年的开发实践为基础,对目前在塔河油田广泛应用的掺稀降粘工艺的机理、实践等各个方面进行了详细分析和探讨。研究认为,常规的热采工艺不适合塔河油田,掺稀降粘、大工作制度生产、掺热稀油生产、复合接力泵工艺技术、化学降粘等都是一些行之有效的开采工艺,塔河油田的开发为我国超深超稠油藏的开采提供一个可以借鉴的开采经验。

Abstract:

Tahe Oilfield is the first superdeep and superheavy carbonate reservoir discovered in China so far,with a buried depth of 5350-6600m and 80% of the reserve is superheavy oil.There is a huge difficulty in developing such a kind of reservoir.Based on nearly 10 years′ developing experience,the influencing factors of the mechanism of light oil blending for viscosity reduction and the operating practices widely used in this field at present are analyzed in detail.Research indicates conventional thermal methods are not suitable for the Tahe Oilfield ,and light oil blending,largescaled operation,hot light oil blending,compound relay pump,chemical viscosity reducers are effective techniques proposed in practice.The development of Tahe oilfield provides adaptable experience in developing super deep and heavy oil reservoir.

Key words: Tahe Oilfield, superdeep reservoir, super heavy oil, exploitation, light oil blending for viscosity reduction 
