Abstract

Abstract: Since there is not yet a perfect target area optimization system established for the exploration and development of unconventional oil and gas fields in China, based on the existing development evaluation theories for unconventional oil and gas fields, referring to the experience and reasonable methods of foreign unconventional oil and gas field development evaluation system, in combination with the geological characteristics of unconventional oil and gas fields in the Ordos Basin, 10 influencing factors were selected, including shale resource abundance, effective shale thickness and maturity in actual blocks, an optimization system integrating structural equation model and fuzzy integral evaluation was conducted. The application was excellent. It was found in the study that the evaluation method based on structural equation model could objectively and comprehensively identify the influencing factors of the target area optimization system, and calculate the weight of each influencing factor, making the evaluation results more objective and accurate, and providing a certain theoretical basis for decision makers. There is much for reference of the results of the study to the exploration, well deployment and enhanced oil recovery of unconventional oil and gas reservoirs.

Key words: unconventional oil and gas reservoirs, favorable area optimization, structural equation, target system, evaluation result
