摘要:
台兴油田QK-111断块阜三段油藏为中-低渗复杂断块油藏,经过15 a水驱开发整体进入高含水递减开发阶段,注气前油藏综合含水74%,采出程度仅14.7%,处于低效开发状态。为恢复断块产量、提高油藏原油采收率,实施CO2驱现场试验,研究形成了高含水油藏剩余油微差异刻画技术、CO2驱油机理认识、注采参数优化方法以及CO2驱细分开发技术,已应用于4个注气井组,累计注入CO2气4.17×104 t,油藏日产油水平由9 t提高到28 t,综合含水由78%下降到44%,累积增油11 183 t,预计方案全面实施后,原油采收率将提高9.6%,年增油量超过1.3×104 t。
Abstract:
Fault block of QK-111 reservoir with medium-low permeability is located in Taixing Oilfield,whose oil-bearing formations are the third formation of Funing.It has been in the inefficient decreasing development state after 15 years of water flooding,with composite water cut 74% and recovery degree of only 14.7%.CO2 flooding field tests were implemented in order to enhance reservoir oil recovery.Many technologies were applied to this project,which include the study the distribution of remaining oil in high water-cut reservoir,optimization methods of injection and production parameters,CO2 flooding mechanism study and layering Technology of CO2 flooding technology.The amount of CO2 injection is 4.17 × 104 tons in four gas injector group,oil production per day increased from 9 tons per day to 28 tons per day,composite water cut from 78% to 44%,cumulative oil production have increased by 11 183 tons.When the plan is carried out completely,oil recovery will increase by 9.6%,and the amount of oil production will increase more than 1.3 × 104 tons every year.
