页岩气资源评价技术

Shale Gas Resource Evaluation Technology

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。

This paper studied the evaluation technology of the shale gas resource, key parameters and the exploitation evaluation with literature data means. It is needed to find out the total reserves of the gas in the initial stage of exploration, The fast and reliable methods are used, that are analogy and volume methods.The calculation key is the number of energy evaluation method, evaluation index organic carbon, maturity,thickness, and brittle minerals contain, the difficulty is the development difficulty, the level of the gas and the gas storage level.
