摘要/Abstract

摘要： 针对中国非常规油气田勘探开发目前尚未建立完善的目标区优化体系的现状,在现有非常规油气田开发评价理论的基础上,借鉴国外非常规油气田开发评价体系的经验和合理方法,结合鄂尔多斯盆地非常规油气田地质特征,选取实际区块页岩资源丰度、页岩有效厚度、成熟度等10种影响因素,建立了结构方程模型与模糊积分评价相结合的优化体系,开展非常规油气田不同指标体系选区优化研究,应用效果较好。研究表明,基于结构方程模型评价方法能够客观、全面地识别目标区域优化系统的影响因素,并计算出各影响因素的权重,使评价结果更加客观准确,为决策者提供一定的理论依据。研究成果对非常规油气藏的勘探、井位部署及提高采收率具有一定借鉴意义。

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
