渤海油田海上平台生活污水回注地层可行性研究

open access: yesGongye shui chuli, 2016
为积极响应渤海海域清洁生产的倡议,进一步保护海洋环境,提出将海上平台水质较好的灰水处理后经由平台注水系统回注地层的新思路。采用Scalechem软件,模拟预测灰水回注过程中在生产处理流程和注水层位的结垢趋势,并通过实验分析灰水回注对生产处理流程的影响,同时提出应对措施。研究结果表明海上平台灰水回注可行。灰水回注可减少70%以上的生活污水排放量,从而削减生活污水的COD排放总量。

Governing Cybersecurity in the Digital Age: Mapping Comprehensive Policy Mixes With the Nodality‐Authority‐Treasure‐Organization Lens

open access: yesReview of Policy Research, Volume 43, Issue 4, July 2026.
ABSTRACT The accelerated digitalisation of society has amplified cybersecurity threats and revealed their cross‐sectoral nature. Yet, the policy instruments used to address these challenges remain insufficiently examined. This study conducts a scoping review of 980 academic articles (2007–2024) and applies Hood's NATO framework (Nodality, Authority ...

稠油RO浓水回注稀油井区研究

open access: yesGongye shui chuli, 2020
新疆风城超稠油油田采用反渗透工艺对采出水进行降盐处理,在生产低盐水过程中同时产生浓盐水,即RO浓水。针对RO浓水回注乌36稀油井区展开了实验研究。结果表明:RO浓水满足乌36井区注水指标,对储层的损害弱,是良好的注水水源。RO浓水几乎无硬度,稳定性好,与乌36地层水配伍性好,在注水生产过程中不会发生结垢问题。RO浓水水温较高,可降低原油黏度,有助于提高原油采收率。使用RO浓水代替清水回注,可减少废水排放量,节约清水资源。
