摘　　要：为研究砾石充填防砂过渡带对水平井产能的影响,将井筒管流与油藏渗流相耦合,在描述过渡带渗透率及半径等相关物性的基础上,建立考虑砾石充填防砂过渡带影响的水平井产能预测模型,并对产能影响因素进行分析。研究表明:考虑过渡带影响的水平井产能计算结果与油井实际产能较接近,不考虑过渡带影响的水平井产能预测值偏大;井筒内压力由趾端向跟端不断下降,而井筒入流量不断上升,二者均表现为近趾端处变化幅度小,近跟端处变化幅度大;水平井产能随过渡带渗透率的增大而增大,随过渡带半径的增加而减小。To study the influence of gravel packingsand control transitional zone on horizontal well productivity,considering wellbore pipe flow and coupling seepage,and based on transitional zone permeability and radius and related propertiesformula,aproductivity prediction model for horizontal wells that takes into account the effects of gravel packing sand control transitional zones is established in this paper,the influencing factors of production capacity are also analyzed.The results show thatthe horizontal well productivity calculationwhich considers the influence of transitional zone is close to the actual oil well production,while theprediction which does not consider the effects of transitional zones is generally high.Wellbore pressure continues to decrease from the toe to the heel,fluid into the wellbore flow is corresponding increasing,both of them show a small change near well toe and a big change near well heel.Horizontal well productivity increases with increasing of transitional zone permeability,and decreases with increasing of the transitional zone the radius.
