摘要
吉林油田低渗透油藏95%以上采用注水开发的方式,而注入水大多是污水回注,因此,有必要对其水质情况进行研究,改善水质,从而提高油层采收率。以吉林油田八面台油田方44、方68两个区块储层为研究对象,从目前注入水水质现状分析入手,对注入水与地层水的配伍性、注入水与地层的敏感性、注入水水质对储层的影响等进行研究,内、外因相结合,综合分析注水伤害情况,给出水质改善建议。
More than 95% of low permeability reservoir in Jilin Oilfield use the development way of injecting water, and injected water are mostly recharged water, therefore, it is necessary to study water quality and improve water quality, so that the oil recovery can be enhanced. Fang 44 and Fang 68 blocks of bamiantai Oilfield are as exemples for the study of reservoir, to analysis the current status of the injected water, compatibility with formation water and the sensitivity with formation and the impact to the reservoir, analysis comprehensively injected water damage from the combination of external factors and internal factors and give suggestions for improvement of water quality.
