However, the safety distance for the control system of the Christmas tree has not yet been effectively determined, primarily due to the lack of accurate assessment of the gas ignition conditions. To scientifically evaluate the blowout-induced combustion and explosion risks of ultra-high-pressure gas mixtures in ultra-deep wells, this study conducted ignition experiments and developed a theoretical prediction model to comprehensively analyze the ignition sensitivity parameters and explosion hazards of gas mixtures at 175 MPa. The results show that increasing the ignition energy from 20 mJ to 1000 mJ lowers the lower explosion limit (LEL) by 13.77 %, while raising the hot surface ignition temperature from 820 °C to 1600 °C reduces the LEL by 11.92 %. Under blowout conditions, the explosion overpressure decreases from 1.90 bar to 0.94 bar—cut nearly in half—and the flame temperature drops from 754.21 °C to 621.34 °C, indicating a substantial reduction in explosion severity. With increasing initial pressure, fewer cracks appear on the surface of spherical flames of the same radius, suggesting enhanced flame stability. Based on thermodynamic and heat transfer theory, a theoretical prediction model for the minimum ignition energy (MIE) of blowout gas mixtures was proposed, incorporating analysis of energy loss mechanisms. The model's prediction error remains within 30 %.

To assess the impact mechanism of surfactant treatment on the safety parameters of dust explosion, this study selected three typical surfactants (SDS, Triton™ X 100, and CTAB) and systematically investigated the evolution rules of the explosion hazards of coal dusts with different degrees of coalification (lignite, bituminous coal, anthracite).Using a 20-L explosion chamber, the explosion parameters (P<sub>max</sub>, (dP/dt)<sub>max</sub>) were measured. The thermodynamic behavior and functional group evolution were analyzed by integrating TG/DTG-DSC and FTIR techniques.

Specifically, SDS treatment significantly enhanced the explosion pressure of lignite (with a 13.0 % increase in P<sub>max</sub>) while inhibiting the explosion reaction of anthracite. Triton™ X-100 generally reduced the explosion risk but exhibited coal-ank sensitivity (the inhibition efficiency of lignite was merely 18.7 % of that of anthracite).Mechanistic studies indicate that surfactants alter the reaction pathway by regulating the key active sites (hydroxyl/oxygen-containing functional groups) of coal-oxygen recombination. Hydroxyl groups play a dominant role in the explosion-enhancing effect of low-rank coal, while the explosion inhibition of high-rank coal is associated with the recombination of oxygen-containing groups.

Current research underscores that dynamic risk assessment has become the dominant method for evaluating oil depot risks, enabling effective identification of risk fluctuations and providing dynamic risk warnings and decision support. Given the critical role of oil depots in national energy infrastructure, ensuring their reliability and safety is essential for safeguarding energy security. However, significant challenges persist in addressing cognitive and aleatory uncertainties. Existing approaches often rely on fuzzy logic and expert elicitation to manage cognitive uncertainty, yet the subjectivity and variability among experts can introduce uncertainties in weight assignments, potentially undermining decision accuracy. Future studies should investigate fuzzy cognitive maps and data-driven methods to mitigate these effects. For aleatory uncertainty, while conventional probability statistics are widely used, further advancements are required to enhance computational efficiency and accuracy. Promising solutions include grey system theory, Bayesian networks, and multi-source information fusion techniques, which offer improved approaches for handling aleatory uncertainty. Developing robust risk assessment frameworks is crucial for protecting energy infrastructure, ensuring the continuity of energy supply, and preventing catastrophic failures. Future research should focus on comprehensive uncertainty management frameworks, improved data quality, and the integration of Internet of Things (IoT) and artificial intelligence technologies to enhance the scientific rigor and reliability of oil depot risk assessments.
