摘　　要：在老井常规重复压裂过程中,常常只是重新压开原缝,而原有人工裂缝附近产层的生产潜能越来越小,措施增油效果逐年下降。因此,使裂缝转向,压开新缝,是老井增产的有效方法。分析了重复压裂的造缝机理、造新缝条件、暂堵剂选择、暂堵剂用量的设计,并把研究应用到准东低渗透油藏上,取得良好的增产效果。Usually hydraulic re-fracturing treatment for old producers only splits the original fractures again.With the development of the oilfield,production potential of the reservoir around the original fractures is becoming less and less,and the effect of enhancing productivity decreases year by year.To turn around fracture and create new fracture are an effective way for old producers to increase production.In this paper,the mechanism of fracture creation for re-fracturing,the condition of new fracture creation,the optimization of block agent and its volume are studied.This study is applied to Zhundong low permeability reservoir,and better effect of enhancing productivity is achieved.
