以油藏地质特征为依据，将长庆低渗透油藏划分为低渗透、特低渗透、超低渗透、致密油四种不同类型油藏，并系统研究了不同类型油藏的开发特征和开发规律，包括压力系统变化特征、见效见水特征、产量递减变化规律和含水上升规律，明确了不同类型油藏开发过程中存在的主要矛盾，为制定不同类型油藏稳产对策提供技术支撑。

Based on the geological characteristics and permeability, the authors classify the low permeability reservoirs in Changqing Oilfield into four types i.e. low permeability, very low permeability, ultra-low permeability and dense reservoirs. The development characteristics and law, including changes of reservoir pressure, water flooding response, production decline patterns and water cut increasing law, are also systemically studied. This paper points out the main contradiction existing in the development process of different types of reservoirs, and provides technical support to make the development countermeasures for stabilizing production in different types of reservoirs.
