从1975年开始罗马什金油田进入开发晚期,原油产量不断下降。近14年来,由于完善了开发系统,采用了先进的提高地层原油采收率的方法、技术措施和工艺,罗马什金油田的原油产量开始保持稳定,甚至出现了增长。在开发晚期油田主要致力于两项任务:其一是保证注水波及范围和易采原油储量达到最大化,其二是使难采原油储量投入有效开发。为此进行高效开发的新工艺有:对以前的生产区块的规模进行优化,优化井网部署和井网密度,优化生产井的地层压力和井底压力;完善注水系统;广泛推行提高原油采收率方法。
From 1975 onwards, the Roman Shijin oilfield entered the late stage of development, with the output of crude oil declining continuously. In the past 14 years, due to the improvement of the development system, advanced methods, technical measures and techniques for improving the recovery rate of formation oil, the crude oil output in the Roman Shijin oilfield began to maintain or even increase. In the development of late oilfield is mainly committed to two tasks: First, to ensure water injection range and easy to extract crude oil reserves to maximize, and the second is to make difficult the exploitation of crude oil reserves into effective development. New technologies for efficient development include optimizing the scale of previous production blocks, optimizing well pattern deployment and well pattern density, optimizing formation pressure and bottom hole pressure in production wells, improving waterflooding systems, Yield method.
