本文通过文献资料对比研究了页岩气资源的评价技术、关键参数及可开采性评价。在勘探的初期需要探明气的总储量,国外常采用快速可靠的类比法和体积法;开发过程中,随着开采的进行气量下降则可采用物质平衡递减法或数值模拟法进行计算。能源评估方式及运算当中关键的泥页岩评估指标为总有机碳、成熟程度、厚度、脆性矿物含有数量。开发地点特征及开发难度的评估指标则是开发难度、生气水平和储气水平。
In this paper, we compare the evaluation techniques, key parameters and exploitability of shale gas resources by literature data. In the early stage of exploration, it is necessary to find out the total amount of gas reserves. In foreign countries, fast and reliable analogy and volume method are often adopted. During the development process, the amount of gas may decrease as the mining progresses, and the material balance decrease method or numerical simulation method can be used to calculate. The key assessment indicators of shale in energy assessment methods and operations are total organic carbon, degree of maturity, thickness and amount of brittle minerals. The evaluation of development site characteristics and development difficulty is the development difficulty, angry level and gas storage level.
