Study on influence of reservoir parameters on oil recovery effect of electric heating-assisted steam huff and puff in horizontal wells LI Yuanting, ZHAO Jingkang, AN Yuhua, ZHENG Jinding, DU Enda, LI Bing 2025, 52 (11):  5-8.  Abstract ( 9 )   Save The horizontal well steam huff and puff technology is currently the most commonly used technique for heavy oil thermal recovery. With the increase of reservoir depth,deterioration of reservoir properties,and increase of crude oil viscosity,the injection effect of horizontal well steam huff and puff becomes worse,resulting in a reduction in the economic benefits of oil field development. During the oil recovery process of horizontal well steam huff and puff,the use of electric heating assistance to improve steam dryness,optimize injection profiles,and enhance injection capacity has become a common practice. By adopting reservoir numerical simulation methods,this study investigates the influence of reservoir parameters,such as crude oil viscosity,reservoir permeability and gradient,and distance from the oil-water interface on the heavy oil thermal recovery effect of electric heating-assisted steam huff and puff in horizontal wells,providing a reference for selection in electric heating-assisted steam huff and puff thermal recovery of horizontal wells in the Bohai Oilfield.

Choice of secondary disciplines and demand for guidance among clinical medical students CHENG Binglu, TIAN Tian, ZHANG Xiaoyang, WANG Weisheng 2025, 52 (11):  64-68.  Abstract ( 7 )   Save To explore the intention and influencing factors of the secondary disciplines by clinical medical students,especially to investigate the demand for guidance among medical students during the selection process,a cross-sectional questionnaire survey was conducted to collect relevant information from 650 medical students. The results show that 190 students have already chosen a secondary discipline in clinical medicine,with the most desired secondary disciplines being surgery and internal medicine. Interest is identified as the most important influencing factor. 90% of medical students were very confident in their choices,and 85.2% of them believed that corresponding guidance was necessary during the selection process. Female students,lower-grade students,and those who have not yet chosen a secondary discipline are the key groups. Among the medical students in need of guidance,70% choose clinicians as their mentors and believe that guidance provided before clinical rotations is more valuable to them. This indicates that medical students have high stability in their choice of secondary disciplines,and their choices are mainly based on personal interest. Medical students hope to receive professional guidance from clinicians during the selection process,which should be integrated throughout their entire undergraduate education.

Analysis of microphysical characteristics of a stratiform cloud precipitation in Tianjin during autumn and winter of 2024 WANG Meng, CHEN Hong, SONG Wei, NIE Haohao, WANG Wan, MENG Hui 2025, 52 (11):  94-99.  Abstract ( 9 )   Save This study investigated the evolving microphysical characteristics of a stratiform cloud precipitation event over Tianjin on November 25,2024,which was induced by an upper-level trough. Multi-source observational datasets,including weather radar,millimeter-wave cloud radar,microwave radiometer,and wind profiler radar,were utilized to analyze the variation laws of microphysical characteristics affecting this stratiform cloud precipitation. The results indicated that the eastward progression of the upper-level trough led to enhanced positive vorticity advection ahead of the 500 hPa trough,coupled with convergent ascending motion in the low-level airflow at 850 hPa,thereby providing a robust dynamic lifting mechanism to sustain adequate water vapor supply for precipitation. Vertically,the stratiform cloud exhibited a distinct cold-upper and warm-lower structure. Retrievals from the microwave radiometer revealed that increased water vapor content furnished sufficient moisture conditions for precipitation,with variations in liquid water content showing consistency with changes in radar echo reflectivity and radial velocity. In terms of wind field structure,strong cold advection prevailed in the upper levels,while the lower levels facilitated water vapor transport to the surface; significant vertical wind shear in the middle levels contributed to maintaining the ascending motion. These findings can serve as an observational basis for artificial precipitation enhancement operations targeting stratiform clouds in the Tianjin region. References | Related Articles | Metrics
