加拿大马更些三角洲天然气水合物物化特性和含量

PHYSICAL & CHEMICAL CHARACTERS AND CONTENTS OF GAS HYDRATE RESEARCHES IN MACKENZIE DELTA AREA, CANADA

天然气水合物是一种潜在的能源,对天然气水合物的地学研究和资源评价已引起了世界许多国家的重视。综述了加拿大马更些三角洲地区多年冻土层天然气水合物的地球物理和地球化学特性,总结了多年冻土层中天然气水合物的测井响应特征和资源评价方法,指出897m～1110m层段的天然气水合物平均含量为39%～37.8%,1090m处的含量高达80%。

Gas hydrate are very important because of their vest resources potential, their role as submarine geohzard, and their effects on global climate in the world. The research result of the gas hydrate in the Mackenzie Delta of Canada are discussed in this summary and conclude the physical and chemical properties of the hydrate\|bearing sediments which are drilled from the permafrost and introduce the evaluation of the gas hydrate.
