摘　　要：八面河油田两大稠油区块均为弱胶结成岩相。胶结疏松是造成油井出砂的主要原因,注蒸汽热采亦对储层造成了一定程度的伤害,加剧了油井的出砂。循环充填防砂工艺具有二级拦截过滤体系,较好兼顾了产能和控制出砂要求,防砂强度高,有效期长,工艺适应范围广。Two thickened oil blocks in Bamianhe Oilfield are weakly cemented lithogenous phase. Weak bonding is main reason for sand production in oil wells. Besides, steam-injection thermal drive has somewhat damaged reservoir and intensify the sand production. Circulation pack sand-protection technology, possessing secondary intercept filtering system which meets the requirement of both production capacity and control of sand production, features high intensity and long period of validity in sand protection in addition to its wide accommodation.
