摘要:
下扬子区页岩气潜力的问题一直没有较为明确的认识,其中最基本的一个问题是页岩层系保存条件复杂,有利区带评价难度大。以重点野外露头马家山剖面为研究对象,通过对岩相、烃源岩、储层性能等主要参数分析,对巢湖地区大隆组页岩发育特征及页岩气形成地质条件进行了初步研究。综合研究认为大隆组中下部气源条件良好(海进体系域),有望成为该区页岩气的潜在勘探目标。对大隆组页岩潜力分析不仅对我国下扬子巢湖地区页岩气储层潜力评价有重要价值,也为下扬子地区页岩气勘探开发提供了重要的借鉴。
Abstract:
There has been no clearer understanding of the shale gas potential in the Upper Yangtze area. One of the most basic problems is that the preservation conditions of shale strata are complicated and the evaluation of favorable zones is difficult. Taken the Majiashan section as the research object,which is the key field outcrop,based on the analysis of main parameters such as lithofacies,source rocks,reservoir performance,etc.,it was carried out the preliminary study on the development characteristics of the Dalong Formation shale and the geological conditions for shale gas formation in the Chaohu area. It was comprehensively considered that the gas source conditions are good in the middle and lower parts of the Dalong Formation (the transgressive system tract),which is expected to become a potential exploration target for shale gas in this area. The analysis of shale potential in the Dalong Formation is not only great value for the evaluation of the potential of shale gas reservoirs in the Chaohu area of the Lower Yangtze,but also provides an important reference for the exploration and development of shale gas in the Lower Yangtze area.
