摘　　要：由于京11断块大孔道的存在,使油井暴性水淹,油藏水驱效率大幅降低,对油田开发极为不利。应用脉冲中子氧活化测井技术,依据氧活化剖面资料,实施大孔道封堵试验,对京11断块大孔道进行识别和治理,取得明显效果。There are high-capacity channels existed in Block Jing11, this causes violent water flooding in oil wells, greatly lower the water displacement efficiency, and is very harmful to oilfield development. By applying oxygen activation logging of pulse neutron and conducting plugging seal off the high-capacity channels according as oxygen activation profile, high-capacity channels are identified and harnessed, and good results are achieved.
