This study focuses on the potential application of Azure cloud computing platforms in Cross-border E-commerce operations, especially in Cross-border E-commerce from China to Southeast Asia. First, we review the basic concepts and characteristics of the Azure cloud computing platform and its potential advantages in e-commerce operations, including improving efficiency, reducing costs, and supporting innovation. Then, we analyze the specific application of Azure's leading cloud technology tools, such as Azure Data Factory, Azure Machine Learning, Azure Databricks, and Azure Bot Service, in Cross-border E-commerce operations. And how to use these tools to optimize Cross-border E-commerce operations. In addition, we build an application framework of Azure in Cross-border E-commerce operation optimization, aiming to help Cross-border E-commerce enterprises make reasonable decisions in cloud technology adoption. In the final section, we summarize the main findings and contributions of this study, point out the limitations of the study, and make recommendations for future research. We expect this study to provide a reference for Cross-border E-commerce enterprises to adopt cloud technology, improve operational efficiency and reduce operating costs, and provide theoretical support for future related research.

The coal reservoir in Block M is the low-permeability coal reservoir, in the process of coalbed gas production, since different degrees of blockage occurs in the fracture and pore of the coal reservoir; as a result, the production of coalbed methane is low or shut down. In this paper, the coal rock reservoir in Block M as the research object, and the acidification and blockage removal acid system was selected, and the acidification and blockage removal effect of the optimal acid liquid was evaluated. The coal core soaking experiment was carried out to test the permeability and porosity of the coal core before and after acidification, the experiment showed that the permeability of the coal core was increased to 1.9 to 15.3 times, and the porosity was increased by 0.25% to 3.56%.
