摘　　要：针对超稠油油藏互层状油层井间、层间潜力无法有效动用的问题,运用精细油藏描述技术方法,开展超稠油水平井分层开发技术研究。利用水平井加密挖潜手段,由以前的分层系开发改为目前的分层开发;针对不同油层条件,建立井位部署经济技术界限,进行分层整体规划部署,达到了超稠油持续高效开发的目的。实现部署水平井84口,增加可采储量158.4×104t,对其他同类型油藏开发也具有指导和借鉴意义。Taking into account of the failure of effective producing from inter- well and interlayer potential reserve in the interbedded pay zones of the super- heavy oil reservoir,separate development from super- heavy oil beds in horizontal wells is studied by means of refined reservoir description technique. By use of infill horizontal wells for potential pooling,the previously used separate development from bed sets is changed to the current separate development from beds; for different reservoir conditions,well locations are arranged and economic- technical thresholds are established to realize overall planning and deployment for stratified development,delivering a sustained efficient development of super- heavy oil. 84 horizontal wells are arranged and recoverable reserve is increased by 158. 4 × 104t,providing guidance and reference for the development of similar oil reservoirs.
