摘要
小洼油田洼38块稠油油藏经过15年的开发,已进入高含水阶段,产量持续递减。为改善开发效果,建立一套以水平井为主的边、底水稠油油藏挖潜技术和方法,需要进行油层细分和对比。对比研究中,对前人对比的不合理之处进行了修正,同时总结了扇三角洲地层对比的模式和规律,对类似扇三角洲油藏的地层对比具有指导意义。
Wa38 Block of XiaoWa Oilfield,a heavy oil reservoir, entered into high water-cut stage with continuous production declining after 15 years field development.In order to improve the development level and establish proper technologies and methods of exploiting the potential of the heavy oil reservoir with side-water and bottom-water by drilling horizontal wells,it is necessary to subdivide the reservoir and correlate formations.When doing so,I corrected unreasonable part of previous job,and summarized correlation models and principles about fan delta; therefore it is instructive to the correlation process of similar cases.
