摘　　要：欢东油田稠油油藏经过10多年的开发,主力区块已进入蒸汽吞吐开采后期,后备资源接替不足成为制约油田发展的瓶颈。2006年以来,欢东油田加大了对稠油难采储量研究和动用的工作力度,按照"整体研究、系统解剖、优选目标、滚动发展"的工作思路,对目标区的油藏地质特征进行精细描述,对直井生产特点进行详细分析,采用数值模拟等技术对水平井开发可行性进行综合研究,优选出4个区块进行水平井开发,取得了好的效果,使欢东油田稠油难采储量得到了有效动用。Huandong heavy oil field has been developed for more than 10 years.The principle blocks have entered late stage of cyclic steam stimulation.Lack of backup resource is a bottle neck restricting oilfield development.Since 2006,the oilfield has enhanced the study and recovery of hard-to-recover heavy oil reserves.Reservoir geological characteristics are meticulously described as per the thought of 'integrated study,systematic dissection,object optimization,progressive development'.The production performance of vertical wells is analyzed in detail.The feasibility of horizontal well development is studied by numerical simulation.4 blocks are selected to carry out horizontal well development and has achieved good effect.Hard-to-recover heavy oil reserve in Huandong oilfield has been produced effectively.
