摘 要: | 通过X衍射、扫描电镜等分析,研究了区块内富有机质泥页岩的储层特征,探讨了区内富有机质泥页岩的储层影响因素。临安地区富含有机质泥页岩的脆性矿物含量整体较高,均大于60%,利于压裂,脆性矿物含量表现为荷塘组高、杨柳岗组次之、胡乐组低;黏土矿物一般小于35%,利于裂缝的形成及吸附,黏土矿物含量表现为胡乐组高、荷塘组次之、杨柳岗组低。整体来看,受构造运动及火山岩影响,临安地区暗色泥页岩的孔隙度和渗透率普遍较低,尤其是杨柳岗组和胡乐组整体偏低。

Abstract: | Based on X-diffraction and scanning electron microscope analysis,the reservoir characteristics of organic-rich shales in Lin'an area of Zhejiang were studied,and the influencing factors were discussed.The brittle mineral content of the organic-rich shales is generally higher,with average contents more than 60%,which is good for fracturing,the performance of brittleness mineral content in Hetang formation is higher,followed by Yangliugang formation and Hule formation.The clay minerals content is generally less than35%,conducive to the formation of cracks and adsorption,the performance of clay mineral contents in Hule formation is higher,followed by Hetang formation and Yangliugang formation.As a whole,affected by volcanic and tectonic movement,the porosity and permeability of the organic-rich shales in Lin'an area is generally lower,especially in Yangliugang and Hule formations. |
