摘　　要：针对大庆油田厚油层地质特点 ,设计了不同的物理模型 ,并利用该模型研究了厚油层层内调剖的潜力以及不同渗透率下 ,水驱、聚合物驱与弱凝胶调剖的效果对比 ,并对不同油藏条件下的深部调剖影响因素进行了分析。This paper designs different physical models according to the geologic characteristic of the thick reservoirs in Daqing Oil Field. Using these models, it studies the potentiality of internal profile controlling of thick reservoirs, compares the effect of water flooding, polymer flooding and weak gel profile controlling in different permeability condition, and analyzes the effecting factors of deep profile controlling in different reservoir condition.
