摘　　要：为了提高塔河油田深层河道砂油藏采收率,首次采用聚合物凝胶体系+聚合物颗粒+表面活性剂体系调驱。本文通过对聚合物凝胶、聚合物颗粒、驱油用表面活性剂进行室内评价,筛选出一套满足塔河油田深层河道砂油藏用的调驱体系,采用聚合物颗粒与聚合物凝胶体系对中高渗层和水流优势通道形成有效封堵,再通过驱油用表面活性剂OWT-1提高洗油效率,从而提高对应油井产量。现场试验两个井组增油效果显著,单井平均降水30%以上,累计增油2847吨,有效期达到180天以上。In order to improve the recovery of Deep Streamway Sand Reservoir in Tahe oilfield,Polymer Gel system+Polymer particles+Surfactant system was used for the first time.Through the indoor evaluation of Polymer Gel,volume expansion particles and surfactant for oil displacement,A set of profile control and displacement system that can meet the needs of Deep Streamway Sand Reservoir in Tahe oilfield is selected.The Particles and Polymer Gel system are used to block the medium high permeability layer and the dominant channel of water flow,and improve the oil washing efficiency through the Surfactant OWT-1,so as to improve the production of corresponding oil wells.In the field test,the oil increase effect of the two well groups is remarkable,the water cut of single well is reduced by more than 30%,and the total oil increase is 2847 tons,and the validity period is more than 180 days.
