鄂尔多斯盆地东缘上古生界页岩特征及含气量

鄂尔多斯盆地上古生界石炭二叠系海陆过渡相泥页岩发育，前人对盆地内上古生界泥页岩已做了多项研 究，而盆地东缘钻井资料较少，研究程度较低。为了弄清盆地东缘泥页岩的特征及含气性，通过野外实测剖面台头剖 面的沉积、地化、岩性、物性等参数并结合等温吸附、核磁共振实验结果，对盆地东缘泥页岩进行分析。研究认为：盆 地东缘上古生界以太原组发育的泥页岩最佳，厚度25 m 左右，有机质丰度较高，处于产气态烃阶段，泥页岩中非膨胀 性黏土含量较高，裂缝/微裂缝发育程度较均匀；同时提出了应用深度和有机碳含量计算吸附气量的公式并通过计算有 效孔隙度提高了计算游离气量的精度。经鄂尔多斯盆内钻井榆88 井的相关数据验证，文中方法所计算的含气量更符 合实际情况，且简单实用。

RESEARCH ON THE CONSTRUCTION OF PUBLIC SERVICE PLATFORM OF LOW CARBON TECHNOLOGY:PROBLEMS AND COUNTERMEASURES

The low-carbon technology innovation is the key to the implementation of the scientific outlook on development,to the realization of energy conservation and emission reduction,and a low carbon economy development.To promote low-carbon technology innovation,we need to build a perfect public service platform of the low carbon technology.In China,the construction of the public service platform of low carbon technology lags behind,which is mainly due to the following problems:inadequate investment,relatively weak resources conformity ability,imperfect technology system,and lack of low carbon professionals,etc.The construction of the public service platform of low carbon technology can be achieved by improving ideology and overall planning,increasing and diversifying investment,integrating resources,and by optimizing national and local low-carbon innovation system,etc.
