A method for scientifically site underground gas storage

A method for scientifically site underground gas storage includes such step as selecting location of gas storage, mathematical model and quantitative evaluation through practice of scheme design and production operation of gas storage group in Dagang harbor. The invention realizes evaluation and optimization by establishing evaluation elements and boundary standards of underground gas storage site, Based on fuzzy set theory, the evaluation objects are sorted according to their comprehensive scores, According to the value on the fuzzy evaluation set, the grade of the object is evaluated according to the principle of maximum membership degree, thus the mathematical model of reservoir site evaluation is established, and the scientific quantification of reservoir site selection is realized. The key technology of underground gas storage construction is not only supported by theory, but also by technical innovation, which is proved by practice and can be popularized and applied. 本发明公开了种地下储气库科学选址方法，通过对大港储气库群方案设计与生产运
