摘要
水合物稳定带 (HSZ)控制着海底天然气水合物的成矿作用和分布规律 ,其厚度及分布范围决定了天然气水合物的蕴藏量 ,所以水合物稳定带的分析对天然气水合物的成矿与分布规律、成因与演化机制以及资源评价研究具有重要的指导意义。水合物稳定带本身受海底温度、压力和甲烷量等因素的影响 ,其变化会影响水合物稳定带的范围、稳定带底界的位置 。
Hydrate stability zone(HSZ)controls the deposition and the distribution of marine gas hydrate,and its thickness and distribution range determines the reserves of the marine gas hydrate.So the analysis of hydrate stability zone(HSZ) is useful to the study of the deposition,distribution,genesis,evolving mechanism and the resource evaluation of the marine gas hydrate.This paper systematically introduced the main characters of hydrate stability zone(HSZ),such as its formation,its temperature pressure characters,and its geologic charactes.The paper also discussed the relationship between hydrate stability zone(HSZ) and hydrate deposition zone,the relationship between the base of hydrate stability zone and the top of free gas,the changes of hydrate stability zone and its influential factors.
