摘要
国家战略要求河南省大力发展清洁能源替代煤炭,页岩气作为高热值、低排放、相对清洁的化石能源,成为目前可行性较高的能源替代选择。河南中部地区近年开展了页岩气调查研究及勘查工作,落实了区内太原组和山西组海陆过渡相页岩气储层,MY1和ZDY2两口探井经压裂后分别获1256 m^(3)/d和3614 m^(3)/d试气产量,但在此发现之后勘查进展停滞。针对该地区页岩气储层,通过资料分析、样品测试和探矿工程等手段,从岩性、物性、有机地球化学特征和探井试气产量等方面对比研究,认为其储层特征与国内海相和陆相页岩气储层存在显著差异,具有普遍含气但开采难度大的特点,在具备资源潜力的同时,仍迫切需要解决地质与工程方面的诸多问题,才能有效推进资源勘查和利用。
According to the national strategy,clean energy is greatly required to replace coal in Henan Province.As a fossil energy mineral with high calorific value,low emission and relatively clean energy,shale gas has become a feasible alternative energy.In recent years,through research and exploration on shale gas in central Henan,the marine and continental transitional shale gas reservoirs of Taiyuan and Shanxi Formations have been identified.After fracturing,exploration wells,MY1 and ZDY2 have obtained 1256 and 3614 m^(3)/d of tested gas production,but after this discovery,the progress stopped.By means of data analysis,sample testing and exploration engineering,shale gas reservoirs in this area are compared and studied from lithology,physical properties,organic geochemistry characteristics and gas test production.It is believed that the reservoir characteristics are greatly different from those of domestic marine and continental shale gas reservoirs,which are generally gas bearing but difficult to exploit.In order to promote exploration and utilization,there is still an urgent need to solve geological and engineering problems while possessing the resources potential.
