摘　　要：在油气井目的层酸化压裂施工时,由于近井地带污染严重或储层渗透性较差,会导致酸压时施工压力较高,甚至无法压开地层。柯探1井酸压时提出一种用连续油管替酸,破堵井周地层后,起出连续油管,再进行常规酸压的施工方法,达到了在低施工压力的情况下进行储层改造的目的。事实证明,该方法在柯探1井当中施工效果良好。During the acid fracturing construction of the target formation of oil and gas wells,due to the serious pollution near the well or the poor permeability of the reservoir,the construction pressure during acid fracturing is high,and even the formation cannot be broken.During acid fracturing of well Ketan 1,a construction method of using coiled tubing to replace acid,breaking and plugging the formation around the well,pulling out coiled tubing,and then carrying out conventional acid fracturing is proposed.The purpose of reservoir reconstruction under low construction pressure is achieved.It has been proved that this method is effective in well Ketan 1.
