渤海油田低效井治理措施浅析

Analysis on Treatment Measures of Low Efficiency Wells in Bohai Oilfield

渤海油田是目前中国最大的海上油田,也是全国第二大原油生产基地,渤海海上石油开采是我国海洋石油开发的先驱,至1966年成立至今,已经开发几十年,目前渤海油田正处于稳产时期,由于油井的储油量越来越少,而大批量的开发井难度也越来越大,随着渤海油田的持续开发,越来越多的低效井面临开发困难的问题,本文通过分析低效井产生的原因,并提出综合治理方案,从而使低效井焕发第二春,为渤海稳产3000万t做出贡献。

Bohai Oilfield is currently the largest offshore oilfield in China and the second largest crude oil production base in China.Bohai offshore oil exploitation is a pioneer in the development of offshore oil in China.It has been in development since 1966 and has been developed for decades.During the period of stable production,as the oil storage capacity of oil wells is getting less and less,the development of large-scale development wells is becoming more and more difficult.With the continuous development of Bohai Oilfield,more and more low-efficiency wells are facing difficulties in development.This paper analyzes the causes of lowefficiency wells and proposes a comprehensive treatment plan,which will make the low-efficiency wells glow for the second spring and contribute to the stable production of 30 million tons in Bohai.
