摘　　要：对春风油田薄浅层超稠油开发效果进行了评价研究。水平井蒸汽吞吐开发技术利用水平井增大泄油面积,蒸汽在水平井段上部形成蒸汽腔室,实现隔热保温驱油。矿场实践证实水平井蒸汽吞吐辅助氮气、降粘剂开发薄浅层超稠油是可行的。稠油产量周期内、周期间快速递减的规律不可改变,但可以通过技术配套和加强管理减缓递减。通过开发规律研究,为指标预测、开发决策提供了依据。对于较厚油层,可以采用蒸汽吞吐辅助氮气、降粘剂开发。春风油田已建成产能65万吨/年,累产油115万吨。According to the primal problems of super heavy oil in Chunfeng Oilfield with shallow buried depth, thin reservoir, underground high crude oil viscosity, crude oil with poor mobility and big development difficulty, this paper puts forward a kind of horizontal well composite oil production technology （HDNS）. HDNS technologica core is horizontal well with steam stimulation, viscosity-reducer and nitrogen aided to improve the efficiency of cycle steam. Nitrogen and steam formed steam compartment in upper horizontal section to heat-insulation and o displacement. Field test proves that HDNS is feasible for thin shallow super heavy oil development. During super heavy oil production period, the principle of rapid progressive decrease between the progressive decrease can be slow down by technical allocation and strengt pen hen ods cannot be changed, but ng management. Based on development law research, the paper provides basis for index prediction and development decision-making Chunfeng Oilfield thin shallow bed super heavy oil is effectively developed, existing productivity is 650kt/a, accumulated oil production is 1 150kt.
