| 摘 要： | 利用物理模拟实验和油藏数值模拟技术,研究了稠油油藏蒸汽吞吐后期转热水添加氮气化学剂泡沫驱提高稠油采收率的开采机理;对合理工艺参数进行了优化,包括化学剂注入速度、注入浓度、气液比、注入方式及段塞大小等.在此基础上,针对辽河油田锦90块的油藏地质特点和开采现状,进行了开发指标预测,设计了先导试验方案.热水添加氮气化学剂驱油技术在矿场先导试验井组中已取得了较好的开采效果,单井组累积增油21378t.目前已扩大到9个井组进行试验,预计这种技术将成为此类稠油油藏蒸汽吞吐后期有效的接替方式.

| Abstract: | The production mechanism for enhancing recovery of depleted heavy oil reservoir with hot water flooding by adding nitrogen and surfactant was investigated.The operating parameters were optimized,by means of numerical simulation and laboratory experiment.The reasonable operating parameters include hot water injection rate,surfactant concentration,nitrogen-to-liquid ratio,injection scheme and the size of slug.Based on the results of laboratory test and simulation,the recovery performances were predicted,according to the relevant of reservoir characteristics and development status of J90 Block.A field pilot test project was designed and implemented to evaluate the effectiveness of hot water flooding by adding nitrogen and surfactant,after steam simulation in a reservoir with a nine-spot pattern at J90 Block of Liaohe Oilfield.The pilot test showed good recovery performances of this method.Currently,the field test has been extended to nine patterns.It is predicted that this technology may become an effective recovery process following steam stimulation for this type of heavy oil reservoirs. |
