摘　　要：倒灰法打水泥塞工艺是利用抽汲绳将油管或专用装灰筒及倒灰工具下到预定深度,在1m范围内上提下放数次,使倒灰孔打开,实现水泥浆从油管流入井筒,同时胶塞从护套中推入套管实现地层封堵。与常规打水泥塞方法相比较,该工艺具有施工时间短、工序少、一次成功率高、成本低等特点。经过现场试验,效果良好,在吉林油田已推广使用。Tech of setting cement plug by infilling Cement is to send tube, cement filling sleeve and its tools to the predictive depth by swabbing rope. Hoisting or lower ing rope for many times within 1 meter is to open the cement infilling hole, rea lizing that of cement slurry flowing to bore hole from tube, meanwhile, of the r ubber plug being pushed in case to packer formation. Compared to conventional one, this tech has features of short operating time, less procedure, high successf ul ratio once time and low cost. By field applications, it is shows that its res ult is perfect and popularized in Jilin oilfield.
