Abstract:

The development of the natural gas hydrate reservoirs has the typical characteristics of high risk, high difficulty and high investment, so the correct evaluation of development quality is a prerequisite and the key to the issue. In order to solve the problems that the evaluation index has limitations and the evaluation results has ambiguity for the development of the natural gas hydrate reservoirs, the factor set is chosen based on the main controlling factors, and the scoring criteria of main controlling factors are defined. The weight set is established by the comprehensive weight calculated by analytic hierarchy process, and then fuzzy comprehensive evaluation of development quality of natural gas hydrate reservoir is further completed. This method is used to evaluate the development quality of Messoyakha and other typical natural gas hydrate reservoirs, and the applicability and feasibility of the method are verified, so as to provide theoretical basis and technical support for the efficient development of the natural gas hydrate reservoirs.

Key words: natural gas hydrate, development quality, fuzzy comprehensive evaluation, qualitative evaluation, analytic hierarchy process
