胡尖山油田侏罗系油藏开发技术政策探讨

Discussions on the Technological Policy of Jurassic Reservoir Development in Hujianshan Oilfields

在区域沉积背景的基础上,立足生产动态资料,重点分析了长庆油田第六采油厂胡151延9、安65延9及油藏的开发特征,从控制采液强度,抑制底水锥进,合理注采比,提高注水见效程度等几个方面对侏罗系油藏进行开发效果分析,通过研究油藏开发现状,结合生产动态数据及生产中存在的实际问题,从控制采液强度,抑制边水推进,合理注采比,提高注水见效程度等几个方面对该区以后的高效开发进行探讨,提出稳产思路及技术对策。

Based on the background of regional sedimentation and the dynamic data of production, the analysis focuses on the well Yan9 of Hujianshang 151, Yan9 of An 65 in the Sixth Oil Production Factory of Changqing Oilfields, as well as the characteristics of the oil reservoir exploitation. Then, the effects of Jurassic reservoir exploitation are analyzed from the following aspects like controlling the intensity of liquid production, restricting the coning of bottom water, adjusting the ratio of injection to production rationally, and improving the effect of water injection. Meanwhile, according to the above study and the practical problems in the production, the discussion on how to exploit this area effectively in the future is discussed from the same aspects. Finally, ideas of stable production and technological countermeasures are presented.
