摘　　要：我国低渗油藏油气储量丰富,探明储量为141亿吨,占全国油气总储量的49.2%,胜利油田的低渗油藏探明储量占总储量20%。随着油气储存总量的逐步下降,低渗油藏的战略意义日渐提高,高效开发低渗油藏对稳定和发展我国石油工业具有重要意义。“水井功能性减阻增注补能”技术、有效解决了低渗油藏难注入、有效期短的问题,实现低渗油藏水驱大幅度提高采收率的目的,为油田开发提采增效保驾护航。There exists abundant oil and gas reserves in low-permeability reservoirs in china,with proven reserves of 14.1 billion tons,accounting for 49.2%of the total oil and gas reserves in the country.The proven reserves of low-permeability reservoirs in Shengli Oilfield account for 20%of the total reserves.With the gradual decline of the total amount of oil and gas storage,the strategic significance of low-permeability reservoirs is increasing.The efficient development of low-permeability reservoirs is of great significance to the stability and development of China’s oil industry.This research has formed the“water well functional drag reduction,injection and energy supplement”technology,which has effectively solved the problems of difficult injection and short effective period in low-permeability reservoirs,and achieved the purpose of water flooding in low-permeability reservoirs to significantly improve oil recovery,and escorted the development and production efficiency of the oilfield.
