The invention relates to a water identification method based on multi-parameter joint discrimination. The method comprises the following steps: respectively determining respective water identification sensitive parameters of a gas logging technology, an ion chromatography technology, a light hydrocarbon technology and a non-hydrocarbon technology; respectively establishing interpretation standards corresponding to the water identification sensitive parameters of the gas logging technology, the water identification sensitive parameters of the ion chromatography technology, the water identification sensitive parameters of the light hydrocarbon technology and the water identification sensitive parameters of the non-hydrocarbon technology; determining a water identification reliability sequence of a gas logging technology, an ion chromatography technology, a light hydrocarbon technology and a non-hydrocarbon technology; and judging the water layer based on the determined water identification reliability sequence and the established interpretation standard corresponding to each water identification sensitive parameter. According to the method, fusion and integration of the advantages of emerging and traditional water identification technologies are realized, the reservoir water content identification accuracy is improved, the coincidence rate of fluid property interpretation of the tight sandstone oil and gas reservoir and the carbonate rock oil and gas reservoir is improved, efficient exploration and development of the two types of oil and gas reservoirs are facilitated, and a large amount of funds are saved.

This invention belongs to the field of biomedicine, and specifically relates to the application of FeTMPyP in the preparation of drugs to alleviate ovarian toxicity. This application addresses the issue that combined exposure to MC-LR and NaNO₂ significantly induces nitrification stress in mouse ovaries, leading to follicular barrier disruption and ovarian reproductive endocrine dysfunction. FeTMPyP was selected as an intervention agent, which effectively alleviated nitrification stress induced by combined exposure to MC-LR and NaNO₂ in mouse ovaries, and improved sex hormone disorders, estrous cycle irregularities, and follicular atresia caused by the combined exposure to these two toxins. Simultaneously, it restored the fertility of mice, indicating that FeTMPyP intervention can alleviate ovarian toxicity induced by combined exposure to MC-LR and NaNO₂ in mice. This invention can be used to prepare drugs to prevent and treat diseases related to ovarian toxicity caused by environmental toxin exposure in mice, providing a new approach for the early identification and targeted intervention of ovarian-related diseases.
