摘　　要：系统地分析了陇东地区三叠系油藏重复压裂改造工艺和压裂效果，简述了影响油井产量降低的各种因素，找出了油井重复压裂改造工艺技术存在的技术难题，明确了低渗透油层重复压裂技术发展方向，为今后提高陇东地区三叠系油藏重复改造提出了具体目标。Re-fracturing technique and fracturing effect of the Triassic reservoir in Eastern Gansu are systematically analyzed. Various factors impacting the oil production decline are briefly described. Technical problems in re-fracturing are found out. Re-racturing technology development orientation of low permeability reservoirs is determined clearly. It provides a specific target for improving re-futureing the Triassic reservoir in Eastern Gansu.
