摘要 针对辽河油区稠油开采现状,利用膜分离制氮注氮装置先后开发了氮气隔热助排、氮气隔热采油一次管柱、氮气泡沫调剖工艺技术和蒸汽-氮气混合驱等。从1998年8月至今,在辽河油区推广应用了近千井次,累计增产原油54322t,创效益6308×10^4元,取得了良好的经济效益和社会效益。 According to current state of heavy oil recovery in Liaohe oil province, through film separation nitrogen making and injection device , successively developed are nitrogen insulated cleanup and production string, nitrogen foam profile control process and compound steam - nitrogen drive, etc. From August 1998 till now, these techniques have been used in Liaohe oil province for almost a thousand well times, with cumulative oil increment of 54 322 t and profit of RMB 63.08 million yuan. Good economic and social benefit has been achieved.
