页岩需要含有足够量的天然气才能进行开采。通过实验室页岩气含量测定和理论预测模型研究，对延长地区陆相非均质页岩气进行了研究。确定了控制页岩气含量的关键因素，并根据气体状态方程和新的岩石物理体积模型建立了游离气含量预测模型。从吸附等温线的结果得到的朗缪尔体积常数和压力常数的应用被发现是有限的，因为这些常数很大程度上受实验温度和压力的影响。因此，使用吸附等温线和热力学理论的测量，温度，总有机碳（TOC），和矿物学上的朗缪尔体积常数和压力常数的影响进行了详细的研究。在此基础上，建立了考虑温度修正的朗缪尔压力常数预测模型和考虑温度、TOC和石英含量修正的朗缪尔体积常数预测模型。使用这些校正的Langmuir常数，应用程序的Langmuir模型确定的实验吸附等温线外推到储层的温度，压力和岩性条件，并建立了一种方法，用于预测页岩气含量使用测井。最后，将该方法成功应用于YC地区陆相页岩地层的页岩气含量预测，实际应用效果良好，精度较高。
Shale needs to contain a sufficient amount of gas to make it viable for exploitation. The continental heterogeneous shale formation in the Yan-chang (YC) area is investigated by firstly measuring the shale gas content in a laboratory and then investigating use of a theoretical prediction model. Key factors controlling the shale gas content are determined, and a prediction model for free gas content is established according to the equation of gas state and a new petrophysical volume model. Application of the Langmuir volume constant and pressure constant obtained from results of adsorption isotherms is found to be limited because these constants are greatly affected by experimental temperature and pressures. Therefore, using measurements of adsorption isotherms and thermodynamic theory, the influence of temperature, total organic carbon (TOC), and mineralogy on Langmuir volume constants and pressure constants are investigated in detail. A prediction model for the Langmuir pressure constant with a correction of temperatures is then established, and a prediction model for the Langmuir volume constant with correction of temperature, TOC, and quartz contents is also proposed. Using these corrected Langmuir constants, application of the Langmuir model determined using experimental adsorption isotherms is extrapolated to reservoir temperature, pressure, and lithological conditions, and a method for the prediction of shale gas content using well logs is established. Finally, this method is successfully applied to predict the shale gas content of the continental shale formation in the YC area, and practical application is shown to deliver good results with high precision.
