摘　　要：针对大庆油田厚油层沉积特点和高含水后期剩余油分布规律,应用水平井挖潜技术,开发大庆油田高含水后期厚油层上部剩余油.南一区甲块南1-2-平25水平井的整个水平井段位于目的层的中、上部位,投产初期含水率仅为10.6%,生产6个月,累计产油为16.279×103t.应用实例表明,利用水平井挖潜厚油层顶部剩余油的效果较好.Based on the deposit characteristics of the thick oil reservoir and distribution law of remaining oil in the later period of strong water sensitivity in Daqing oil fields,applying the latent power tapping technology to the horizontal wells,the remaining oil is recovered in the upper part of thick reservoirs in the later period of strong water sensitivity in Daqing oil fields.A better effect is achieved after the application of well south 1-2-ping 25 which is a horizontal well in armor block of south-1 area,the proportion of the sandstone in the 630m of the designed horizontal section is 100%.The whole horizontal section is located at the center or upside of the objective interval;the moisture content is only 10.6% at the initial stage,the verified accumulation output of the oil is 16 279 t after 6 months.It has reached the development result tapping latent potentialities of the remaining oil in the upper part of thick reservoirs.
