Title: NEW RECOVERY TECHNOLOGY OF SUPER-DEEP AND SUPER-HEAVY OIL RESERVOIR DEVELOPMENT OF TAHE OILFIELD
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.
