Rational and efficient development of low permeability reservoirs need to establish an effective driving pressure system, which is the key issue to improve the development of low permeability oil and gas fields. Faced with this situation, this paper discusses the study of low permeability reservoirs in the academic definition of the scope, classification and distribution in our country, and describes the geological characteristics of low-permeability reservoirs, development of reservoir characteristics and ensure the effective development of injection technology; then asked a series of questions based on the presence of water in the feasibility of developing low permeability reservoirs stratified water development, and is currently being applied layering of water injection technology were introduced; Finally, in ChangQing Oilfield stratified injection technology as an example to analyze and evaluate its application results. Key words：Low permeability reservoirs；Development features；Stratified water 目 录 1 绪论 1 1.1 研究的目的及意义 1 1.2 国内外研究现状 1 1.3 研究内容 2 2 低渗透油藏分类及其特征 3 2.1 低渗透油藏的分类? 3 2.2
