中文摘要:
      以山东莱阳盆地莱阳群水南组为研究对象,通过分析水南组岩性特征和沉积环境,发现水南组利于页岩气的形成。对水南组有机地化样品分析研究,有机碳含量介于0.62%~23.00%之间、镜质体反射率介于0.62%~2.14%之间、干酪根类型以Ⅰ,Ⅱ型为主;认为水南组具备页岩气形成的物质基础和地质条件。利用水南组泥页岩的试验测试数据,探讨了水南组泥页岩的游离气含量、吸附气含量和溶解气含量特征及变化规律,获得水南组泥页岩总含气量为1.538m3/t,以游离气含量(占57%)为主,吸附气含量次之,揭示了莱阳盆地水南组页岩气具有一定勘查潜力。
英文摘要:
      Regarding Shuinan formation in Laiyang group in Laiyang basin as the study object, through analyzing lithologic characteristics and sedimentary environment, it is found that Shuinan formation is favorable for the formation of shale gas. The organic carbon contents range from 0.62%~23.00%, the vitrinite reflectance range from 0.62%~2.14%, and the kerogen types are mainly type Ⅰ and type Ⅱ. It is considered that Shuinan formation has the material basis and geological conditions of shale and gas formation. Based on the test data of shale in Shuinan formation, the characteristics of free gas, sorbed gas and dissolved gas in shale have been discussed. The total gas content of shale gas is 1.538m3/t, the free gas content (57%) is the dominant component, and followed by the adsorbed gas content. It is revealled that the shale gas in Shuinan formation in Laiyang basin has a certain exploration potential.
