Gongye shui chuli, 2023 电磁油水分离是一种新型环保高效的油水处理技术，在导电性油水处理方面表现出明显的优势，是目前的研究热点之一。基于胜利油田典型联合站采出液实测电导率，理论分析了油田采出液的电磁分离过程，并对不同含油量油田采出液的电磁分离过程进行了数值模拟和仿真分析；在此基础上结合油田生产过程，提出了电磁油水分离技术在油田中的应用方式。结果表明：油田采出液电磁分离具有超重力分离和气浮分离的优势，分离效率高；对含油104~105 mg/L的采出液，电磁分离可实现原油富集；对含油103 mg/L的采出液，电磁分离可用于回注水处理。

Gongye shui chuli, 2021 为研究致密气采出水回注的可行性，以鄂尔多斯东缘盆地某致密气区块采出水及石盒子组盒8段储层为研究对象，通过水质配伍、黏土膨胀岩心伤害及储层敏感性实验，综合分析采出水水质对回注储层的影响。结果表明：初期采出水经处理后，混合结垢量最大为54 mg/L，配伍性良好；水样无论是单独回注还是混合回注，其黏土膨胀率最大为21.78%，均不会引起黏土膨胀。采出水中悬浮物和含油质量浓度分别限制在10 mg/L和6 mg/L以下，对储层的伤害率低于20%；致密砂岩储层敏感性对回注水主要表现为中等偏弱速敏、弱酸敏。

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, EarlyView.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Gongye shui chuli, 2002 胜利油田已进入特高含水期,原油综合含水质量分数已达到89.9%,随着采出液含水的不断上升,油田回注后,部分采出水需处理后外排。油田采出水温度与矿化度高, 部分污染物在水中以溶解状态存在,水质复杂, 采用常规的物化处理工艺难以有效去除废水中的污染物。

Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, EarlyView.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

The Development and Validation of the Chinese Vocabulary Levels Test
International Journal of Applied Linguistics, EarlyView.ABSTRACT In response to the increasing need for effective Chinese vocabulary assessments, this study developed the Chinese Vocabulary Levels Test (CVLT), a test designed for intermediate‐level Chinese as a second or foreign language (CSL/FL) learners, based on the vocabulary lists (levels 4–6) from the Chinese Proficiency Grading Standards for ...
