This invention belongs to the field of plasmid and mRNA quality control technology, specifically disclosing a method for characterizing plasmid quality. Existing plasmid quality control systems cannot effectively predict mRNA product quality and do not focus on the purity of the PolyA tail. This invention establishes a positive correlation between the purity of the PolyA region in the plasmid and the quality of the mRNA product by detecting its purity, thus achieving early mRNA quality prediction. The prediction method includes the following steps: plasmid sample enzyme digestion, analysis of PolyA fragment purity using capillary gel electrophoresis, and substituting the PolyA fragment purity into a correlation curve to obtain mRNA purity. Based on this, this invention effectively shortens the production cycle, reduces costs, and provides a new evaluation dimension for plasmid quality control by screening plasmids with acceptable PolyA purity for mRNA production.

This invention provides a method, apparatus, equipment, and medium for controlling alternating gas-water injection and production, belonging to the field of petroleum development technology. The method includes: acquiring multiple sets of different injection and development parameters; calling a reservoir development gas-water alternating injection and production model; employing orthogonal design to select the optimal injection parameters from the multiple sets of injection parameters, and calculating the corresponding optimal gas-water ratio, gas slug size, and water slug size. By fixing these optimal parameters and inputting different development parameters into the gas-water alternating injection and production model, the optimal development parameters that maximize reservoir recovery are determined; finally, a gas-water alternating injection and production strategy is generated based on these optimal parameters to guide reservoir development. This invention significantly improves reservoir recovery and development efficiency by optimizing injection and development parameters, while reducing costs and enhancing operational flexibility.
