中国页岩气开发碳排放核算模型构建及研究

Construction and Research of Carbon Emission Accounting Model for China’s Shale Gas Development

以我国开发的页岩气田为研究背景,运用生命周期分析方法,对页岩气开发全过程中的钻井、试气、采气等3个环节分别进行分析和研究,来确定其碳排放边界和存在的碳排放源,并建立具有合理性和适用性的碳排放核算模型。根据上述核算模型,针对我国某页岩气田特征,确定排放因子,并对各排放因子进行了合理的修正,根据其开发过程碳排放量进行实证核算,并对结果进行相应的分析。

Based on the shale gas field developed in China,the life cycle analysis method was used to analyze and study the three stages of drilling,gas testing and gas production in the whole process of shale gas development.The boundaries and existing sources of carbon emissions were determined,and a reasonable and applicable carbon emission accounting model was established.According to the accounting model above,the emission factors were determined for the characteristics of a shale gas field in China,and the emission factors were corrected reasonably.According to the carbon emission of the development process,the empirical calculation was carried out,and the results were analyzed accordingly.
