摘　　要：结合大庆油田台肇地区低渗透裂缝性油藏的裂缝监测结果,针对天然裂缝开启压力不同的特点,提出先封堵地层裂缝,然后实施转向压裂的改造工艺思路,通过封堵剂的优选,封堵工艺的确定及压裂过程中对裂缝方向的监测等技术手段,证实封堵裂缝后转向压裂技术在低渗透裂缝性油藏现场应用可以取得较好效果,为同类油藏压裂改造探索一条有效新途径。Combined with monitoring results of Taizhao low-permeability fractured reservoir in Daqing Oilfield, the opening pressure of natural fractures is different , the literature put forward the reformation technology which plug formation fracture firstly, and then implement turnaround fracture. By optimizing plugging agent, confirming plugging technology and monitoring the direction of fracture, the technology which plug formation fracture and implement turnaround fracture obtain a favourable effect in low-permeability reservoir. All these researches provide a new way for fracturing reformation.
