Development and laboratory test of stored downhole visualization tool PENG Zhengqiang, HUA Zejun, LONG Jiangqiao, HAN Fang, ZHEN Baosheng, GUO Jing 2025, 52 (03):  5-8+12.  Abstract ( 8 )   Save Annual workover workload in offshore oil fields continues to increase. There are complex problems underground,such as string corrosion,scaling,casing deformation,and screen breakage. With the underground situation remaining unknown,it often leads to weak program,and “empty drilling” often occurs. On the basis of the existing downhole visual tools,the development of supporting tools for storage downhole visual equipment is carried out,and a set of storage downhole visual system is designed,so that the visual tools can be inserted into the well with the pipe string,and the washing fluid can be circulated underground,so as to achieve a clear record of downhole conditions and assist the analysis and judgment of well conditions,so as to improve the success rate of the workover plan and the operation efficiency.

Comparison and selection of corrosion control schemes for steel structure facilities in splash zone and tidal range zone of offshore oilfield platforms ZHANG Cuihuan 2025, 52 (03):  9-12.  Abstract ( 8 )   Save The platform of a certain oilfield group has been in service for many years. The anti-corrosion coating on the steel structure in the seawater splashing area and tidal range area has aged,been damaged,and peeled off,losing its protective effect,resulting in an increase in the corrosion rate of the steel structure and affecting the design service life. The offshore oil field group platform is located in a harsh marine environment,which is susceptible to high humidity,high salinity,and corrosive environments,as well as the impact of waves and winter ice ages. Corrosion problems should not be underestimated. A comparative analysis was conducted on the corrosion control schemes and measures for steel structures such as pipeline racks,caissons,waterproof casings,and berthing components located in splash and tidal zones,and the important roles of several schemes in improving platform safety and service life were elaborated.

Application of CAFS for city master firefighting vehicle in firefighting and rescue scenes TIAN Jin 2025, 52 (03):  24-26.  Abstract ( 7 )   Save The application and existing problems of compressed air foam system （CAFS） in firefighting and rescue are discussed,and corresponding countermeasures are put forward. Compressed air foam has a long shelf life and low use cost,but in practical use,there is a problem of low utilization rate. The reasons include weak awareness of the basic performance of compressed air foam among firefighting and rescue personnel,relatively cumbersome combat resupply,and more professional daily maintenance. To improve the utilization rate and firefighting and rescue capabilities of compressed air foam,the following countermeasures are proposed: strengthening professional theoretical foundation,enhancing equipment performance training,strengthening combat support,introducing intelligent management systems,giving full play to the synergistic efficiency of special equipment,and strengthening inter-departmental collaboration and information sharing.

Analysis and treatment of freezing on inner wall of start-up oil supply pipe of a certain aviation auxiliary power unit XIAO Qiu, FANG Bo, JIANG Yi, LIN Qinxue, PI Kaiwen 2025, 52 (03):  35-39.  Abstract ( 7 )   Save During winter in Northeast China,a certain aviation auxiliary power unit frequently fails to start up due to freezing in the start-up oil supply pipe. The analysis shows that the reasons are forced cooling of the helicopter down-wash stream,the partial pressure rise of water vapor in the air after pressurization and a small amount of mixed gas. Water vapor condenses and freezes on the inner wall of the oil supply pipe. When the ambient temperature is low,the condensed water in the start-up oil supply pipe mainly comes from the mixed gas,and the freezing is not closely related to the environmental humidity. The higher the ambient temperature,the higher the proportion of water vapor in the ambient atmosphere in the condensate water of the start-up oil supply pipe,and the greater the impact of humidity. Due to the inability to completely insulate the start-up oil supply pipe,adding insulation sleeves can reduce the frequency of freezing,but the condensed water may still occur. By using a start-up oil drain solenoid valve instead of a start-up cleaning valve,the problem of freezing in the start-up oil supply pipe was solved. References | Related Articles | Metrics

Fault analysis of low-temperature start-up of air compressor on offshore platform and optimization of exhaust duct YU Haocheng 2025, 52 (03):  47-49+54.  Abstract ( 6 )   Save In order to address the high temperature fault of the air compressor on the offshore oil platform during start-up in extremely cold weather,the operating data and alarm parameters of the air compressor were analyzed on site,and it was found that the main cause of the fault was the high temperature of the screw head caused by low oil temperature and poor fluidity. Based on this conclusion,innovative modifications were made to the air compressor sled. Through analysis and comparison of three modification schemes,combined with the actual spatial layout of offshore platforms,it is confirmed that the installation of louver air valves in air-cooled air compressors is the most reliable and operable modification scheme. This modification provides experience for solving similar problems of in-service air compressors in Bohai Oilfield. References | Related Articles | Metrics

Analysis of level of environmental health literacy and influencing factors among residents in Tianjin ZHANG Yuan, ZHAO Yong, CAI Wenbin, ZHENG Yuan 2025, 52 (03):  82-86.  Abstract ( 5 )   Save A multi-stage cluster random sampling method was used to conduct a questionnaire survey on 4 088 permanent residents aged 15-69 in 10 administrative districts of Tianjin. Based on the chi square test and multivariate logistic regression model,this paper explores the level of environmental health literacy among residents in Tianjin in 2023 and its influencing factors,and analyzes the impact of demographic characteristics on the level of environmental health literacy. The environmental health literacy level of Tianjin residents is 26.2%,with literacy levels of basic concepts,basic knowledge,basic behaviors,and skills being 28.3%,27.6%,and 35.8%,respectively. Residential area,age,occupation,and education level have a significant impact on environmental health literacy,while there is no significant difference between genders. The literacy level of urban residents and those with higher education levels is significantly higher than that of rural residents and those with lower education levels. It is suggested that different strategies of science popularization and education should be adopted for different groups of people,especially rural and elderly groups.
