摘要
页岩气是一种重要的非常规天然气资源,目前国内对页岩气储层测井评价方法的研究还处于起步阶段。在对国内外页岩气储层测井评价方法调研的基础上,根据岩心分析资料,建立了四川盆地蜀南地区页岩气测井评价岩石物理模型。通过开展总有机碳含量、吸附气含量及游离气含量等计算方法的研究,形成了针对四川盆地蜀南地区页岩气储层关键参数的计算方法,并开发了相应的测井解释模块,建立了一套系统的页岩气储层测井评价方法。该方法支撑了页岩气试油层段及储层改造措施优选,为四川盆地页岩气藏的勘探开发提供了技术保障。
Shale gas is an important unconventional natural gas resource, and research on well logging evaluation methods of shale gas reservoir is still at the starting stage in China. Based on well logging evaluation methods of shale gas reservoir at home and abroad, a petrophysical model of shale gas reservoir was established by some core data. Meanwhile, methods to calculate total organic carbon content, adsorbed gas content and free gas content were studied, a method to calculate the main reservoir parameter for shale gas reservoir was initially formed, and the corresponding well logging interpretation module was also developed. So, a set of shale gas reservoir logging evaluation techniques was establishment, which can provide guidance and technical support for the shale gas exploration and development in Siehuan Basin.
