| 摘 要： | 湘西北下寒武统牛蹄塘组海相页岩热成熟度高,且经历了多期复杂构造运动,这种有机质高热演化程度及复杂构造条件下的页岩气有利区块优选面临挑战。本研究对影响页岩气勘探开发潜力的各种因素进行了综合研究,确定了页岩气勘探开发潜力评价的4个二级指标(生成条件、储集条件、保存条件和综合配套条件)及相应的三级指标。采用模糊数学方法对各级因素指标赋予了权重,建立了用于页岩气勘探开发潜力评价的多层次模糊数学评判模型。利用该模型,综合评价湘西北地区鹤峰复背斜、桑植复向斜、古丈隆起、沅麻盆地和洞庭坳陷5个Ⅲ级构造单元的页岩气资源勘探开发潜力。研究表明,桑植复向斜最具勘探开发潜力,其次是鹤峰复背斜,沅麻盆地、古丈隆起与洞庭坳陷则相对最差。建立的评价体系,可以作为有机质高热演化程度及复杂构造条件下的页岩气资源开发潜力评价的参考体系。

| Abstract: | Marine shale in Lower Cambrian Niutitang Formation of northwestern Hunan, with high thermal maturity, experienced multi-period structural movement in geologic history, resulting in challenges on selecting the favorable areas of shale gas. The influencing factors of shale gas exploitation potential were investigated. Four second-order indices, including formation conditions, reservoir conditions, storage conditions and integrated matching conditions, and their corresponding third-order indices for assessment of the shale gas exploitation potential were established. The weight values of all second and third-order indices were determined by the fuzzy mathematics and the multi-layered fuzzy mathematics model for evaluation of shale gas exploration potential were set up. The multi-layered fuzzy mathematics model was applied to evaluate comprehensively the exploration potential of shale gas in the third-order tectonic units, including Hefeng anticlinorium, Sangzhi synclinorium, Guzhang uplift, Yuanma basin and Dongting depression. The results showed that Sangzhi synclinorium has the best potential for shale gas exploitation, followed by Hefeng anticlinorium. The assessment system established can be regarded as a reference model in shale gas exploitation potential assessment of shale gas with high thermal maturity and complex geological structures. |
