欢北低渗透油藏二氧化碳驱可行性研究

摘要

欢北低渗透油藏在注水开发中存在油层纵向动用不均、水驱开发驱油效率低等问题.为解决以上问题,在该块开展了二氧化碳驱可行性研究,最后认为该油藏适合注二氧化碳驱开发.%There are some problems in the water injection development of HuanBei low permeability reservoir,such as unequal oil reservoir development,low oil displacement efficiency.In order to solve these problems,the feasibility of carbon dioxide flooding in this reservoir was studied and it was considered suitable for carbon dioxide flooding.
