低渗透油藏注气开发室内实验研究

Laboratory experimental study on gas injection development of low permeability reservoir

对储层物性较差、敏感性较强的低渗透油藏,注水开发难以建立有效驱替系统,开发效果较差。而注气开发具有注入能力强、储层伤害小等技术优势,可有效改善和提高低渗透油藏开发效果。注气开发实施前需开展相关室内实验研究,明确气驱开发机理,指导注气开发方案编制。

for low permeability reservoirs with poor physical properties and strong sensitivity,it is difficult to establish an effective displacement system for water injection development,and the development effect is poor.The gas injection development has the technical advantages of strong injection capacity and small reservoir damage,which can effectively improve and improve the development effect of low-permeability reservoir.Before the implementation of gas injection development,it is necessary to carry out relevant laboratory experimental research,clarify the gas drive development mechanism,and guide the preparation of gas injection development plan.
