摘　　要：吉林油田黑帝庙油层压力不足,原油黏度高,凝固点高,常温下不易流动。针对这一问题开展了CO2蓄能压裂的研究与应用,并在黑+79-31-45井现场应用成功。该技术采用纯液态CO2代替常规水基冻胶压裂液进行造缝和携砂,与常规水力压裂相比在施工设备、地面管线、施工参数等多方面都存在很大差异。CO_2 energized fracturing fluid was studied on its use in the Heidi Temple block in Jilin Oilfield where reservoir formation pressure is low and the crude oil has high viscosity and high freezing point.Unlike conventional water based gel fracturing fluid,pure CO_2 was used in the energized fracturing fluid to create fractures and to carry sands.This technology was successfully applied in fracturing the well Hei+79-31-45.This paper discusses the differences between CO_2 energized fracturing fluid and conventional fluids regarding operation equipment,surface pipelines and operation parameters etc.
