祁连山冻土区木里三叠系烃源岩地球化学特征

为了查明祁连山冻土区木里天然气水合物的气源,开展冻土区三叠系烃源岩研究工作。按照深度顺序,对JN井1 300多米的岩心取芯,然后和露头样品一起进行实验测试。首先对采集到的36个样品进行常规的有机碳和岩石热解实验,分析其成熟度和生烃潜力;然后选出9个样品进行有机岩石学显微组分镜下鉴定;最后遴选出4个样品进行索氏抽提实验并进行色谱-质谱分析检测。研究结果表明,该区三叠系烃源岩基本处于高成熟阶段;有机质为Ⅱ型和Ⅲ型,有机质来源为混源输入,为陆表海-滨海三角洲相沉积;有机质丰度较高,为中等-好烃源岩。综合分析认为,冻土区三叠系烃源岩可能是该区天然气水合物的有利供气源岩。

Geochemical Characteristics of Triassic source rocks from the Muli Qilian Mountain permafrost

The development of industrialization has undergone a fundamental change on agricultural model, while also brought us many other sustainable development issues such as the ecology issues, the environment issues, food safety issues and integrity, health issues. The development of society is always in conflict among the front row, it is the fundamental way for us to achieve sustainable development to solve the problem of agricultural development with industrialization characteristics. The generation and development of "Community Supported Agriculture" model provides us a good idea. This paper explains the inner meaning of the agricultural mode restructuring and development based on the sustainable development of "Community Supported Agriculture" model, and puts forward that in the development of industrial agriculture model, we must pay attention to the development of ecological agriculture model, both of them are indispensable.
