Gongye shui chuli, 2016 地层水与海水是海上注水开发油田的两类重要注入水水源。以A油田为例，结合区域内的地层水和海水特点，建立了海上油田注入水水源的选择方法和依据，并分析评价了不同水源对注水系统的腐蚀影响。研究结果表明，A油田如采用地层水为注入水源，存在硫化氢腐蚀风险，在满足细菌达标、溶解气达到行业标准的基础上，注水系统平均腐蚀速率低于行业标准，能够满足长期注水寿命要求；A油田如采用海水为注入水水源，存在盐和氧腐蚀问题，在满足细菌达标、溶解气达到行业标准的基础上，平均腐蚀速率仍高于行业标准。推荐该区域注入水水源采用地层水 ...

Gongye shui chuli, 2013 歧口17-2油田实行清污混注后,注入水含油浓度超标,急需对水质处理流程进行调整。对注水流程各节点含油浓度的检测结果显示,水力旋流器除油效率低是导致注入水含油超标的关键节点。对水力旋流器运行参数进行了优化,结果表明,当PDR值为1.75,流量为95 m3/h时,水力旋流器除油率可提高到70%以上,注入水含油浓度满足控制指标要求。

Dizhen xuebao, 2021 工业开采注水能导致现存断层活化，从而诱发大量的破坏型地震。因此，研究注水作用下断层的动力学响应对探索诱发地震的力学机理具有重要的意义。本文基于孔弹性弹簧-滑块模型，采用多孔介质弹性耦合数值模拟，计算分析了三类典型注水方式（上升型、迅速上升/下降型和间歇型）对断层稳定性的影响。研究结果表明：随着流体的不断注入，断层内部流体压力会经过缓慢上升、迅速上升和稳定上升三个阶段。针对于不同的注水方式，这三个阶段并不完全相同，体现形式存在差异；在注水方式相同的条件下，储层的渗透率越小，井口附近流体压力越大 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...

Gongye shui chuli, 2012 海上注水开发油田由于受到海洋作业环境与资源限制,注水水源仅能采用有限的地下水以及生产处理污水资源,为此对注入水与储层进行配伍性研究显得尤为重要。通过浅层地下水、生产污水以及混配水与地层岩石的配伍性实验研究,论证不同注入水源对储层的伤害程度,为油田选取最佳清污混配比例提供依据,保障油田在有限的水资源条件下的高效注水工作。

L2 Chinese Grammatical Acquisition and Processing: A Substantive and Methodological Review
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study presents a systematic review of 92 empirical studies on Chinese as a second language (CSL) in grammatical processing and development, synthesizing their substantive foci and methodological characteristics. The results reveal consistent scholarly attention to cross‐linguistic topics, with less focus on features that are distinctively
