“…After using visualization equipment, casing breakage was found at 1530m (Figure 4). [9][10] A newly drilled horizontal downhole scraper in Sinopec was blocked at 2819.14m, and after repeated lifting and lowering without success, the scraper body was found to have scratches. After running visualization equipment, obvious casing deformation traces were found at 2817m (Figure 5).…”

The actual underground situation is of great significance for workover operation. Videolog visualization technology can clearly and accurately obtain the underground color video information, and provide effective guidance for workover operation. This paper introduces the system composition, working principle and functional parameters of Videolog equipment, and gives an example of its practical application in workover operation, which shows that Videolog visualization technology is more efficient, safe and intuitive than traditional downhole video technology, and has a good application prospect in workover operation field.

Abandoned well pollution is a critical component of global environmental issues and a historical legacy issue of national development. Despite this, the specific mechanisms by which abandoned wells pollute groundwater remain unclear, particularly in the karst regions of Northern China, where no scientifically effective remediation methods exist. To address this gap, this study focuses on Yangquan City in Shanxi Province and employs field investigations, the analytic hierarchy process, high-definition deep-well logging technology, and qualitative analysis to assess the pollution risk of all abandoned wells in the study area, identifying those with high pollution risk. Through the analysis of extensive image and video data for these high-risk wells, we propose a conceptual model of cross-strata channels in abandoned wells and elucidate the mechanisms by which they pollute groundwater. The results show that, from a single-well perspective, the pollution mechanism is cross-strata pollution. From a regional perspective, the pollution mechanisms are hydraulic connectivity and solute migration and transformation. Based on these findings, we present a scientifically effective remediation strategy tailored to the typical characteristics of abandoned wells in the study area, offering a viable solution to the abandoned well pollution problem in Yangquan City. This research not only augments the theoretical framework in the domain of groundwater pollution but also advances sustainable groundwater security and management strategies. Moreover, the study furnishes theoretical foundations and pragmatic solutions for the remediation of abandoned wells in Yangquan City, which are crucial for the sustainability of the groundwater ecosystem.
