延长油田纸坊区长2油藏开发效果评价

Evaluation on Development Effect of Chang 2 Reservoir in Zhifang Area of Yanchang Oilfield

应用低渗透油田注水开发效果评价方法,对延长油田纸坊区长2油藏注水开发储量动用及水驱控制程度、地层能量保持状况、注水见效特征、含水变化规律等方面进行了分析,按照行业标准进行了综合评价,针对该油层目前注水存在问题,提出下一步工作方向及建议,以改善油田开发效果,提高油田采收率。

Using the evaluation method of low permeability oil field development effect, based on the analysis of the key controlling factors including water flooding reserve producing and water driving control degree, stratigraphic energy retention, features of the water flooding and changing law of water content, comprehensive evaluation of Chang2 reservoir of Zhifang area in Yanchang oil field was carried out according to industry standards. Aiming at current problems in water flooding, some suggestions were put forward in order to improve the recovery efficiency and development effect.
