摘　　要：根据渗流速度公式推导计算高吸水层渗透率的公式,进而推导出根据注水调配见效时间计算高吸水层渗透率的公式,计算结果和示踪剂结果相近,该公式现场录取参数容易,便于操作。同时推导出计算地层大孔道体积的公式,堵剂用量确定方法,施工排量的确定公式。提出了先小剂量多段塞注入可以在地层凝固的高强度堵剂,再注入常规调剖剂的段塞组合方法,并经过现场应用,见到效果。In the article we inferred high water-intakepermeability formula through permeability velocity formula,then inferred water flood mixing response time to calculatepermeability. The calculated result is close to the resultshown by the tracer material. The parameter is easy to collect for this formula, and it is easy for operation. Simultaneously the formation large pore passage volume formula,plugging amount, construction displacement have been inferred. We proposed at first to pour small dosage highstrength plugging agent which can solidified in the stratuminto more slugs, then pour conventional profile control agent. The field application has shown effect.
