摘要
鉴于目前天然气下游用户不足,气藏生产能力过剩,丘东气处理厂资产闲置和公司原油产量任务过重的实际情况,有必要在现有条件下重新论证丘东气田循环注气提高凝析油采收率及其充当储气库的可行性。应用相态软件 Desktop-PVT 和油藏数值模拟软件 VIP 的组分模型研究分析了循环注气的影响因素,并归纳为六个方面:注采井网、注入剂组分、停注时间、采气速度、注采比和流体性质。
It was necessary to demonstrate the feasibility of improving condensate oil recovery by re.cireulated gas injection in Qiudong gas field and establishing underground natural gas storage,since,on the one hand the gas production had exceeded downstream customers'demands,and on the other hand the goal of crude production rate was difficult to meet at that time.Factors affecting the recirculated gas injection had been analyzed by use of Desktop -PVT software and a compositional simulator of a reservoir numerical simulation software - VIP.It was concluded that the influence factors included injection - production pattern,composition of injectant,time of injection shutdown,gas production rate,the ratio of injected gas to produced oil and fluid properties.
