马更些（Mackenzie）冻土区位于加拿大西北地区，是世界上最著名的天然气水合物产地之一，也是加拿大最重要的含油气盆地之一。在Mallik地区已相继钻探了L-38、2L-38、3L-38、4L-38和5L-38共5个钻孔，并进行了地质、地球物理、地球化学、微生物学和试生产等方面的多学科多方法研究，是目前全球天然气水合物研究程度最高、资料最丰富的地区。“Mallik 2002”项目开展了天然气水合物的短期试生产，共对6个水合物层位进行了降压法试生产并在其中的4个层位取得了成功，同时利用注入约80℃的热流体进行了5天多的加热法试生产，共生产出468 m³的天然气。“Mallik 2002”项目的成功实施是天然气水合物开发利用史上的里程碑，为将来的长期试生产和最终开发利用奠定了基础。随着开发利用研究的不断深入，天然气水合物这一规模巨大的潜在能源有可能在不久的将来为人类社会所用。

The Mackenzie permafrost, located at Northwest Territories, Canada, is one of the most important gas hydrate inventories all over the world and conventional petroleum basins in Canada. Mallik L-38, 2L-38, 3L-38, 4L-38 and 5L-38 wells for gas hydrate or conventional petroleum have been drilled in the Mallik gas hydrate field, the Mackenzie Delta, and a broad of research activities including regional geology, geophysics, geochemistry, microbiology, logging, production testing and modeling, and etc., have been undertaken, which accumulated a vast amount of data and technical research papers. Therefore, the Mallik gas hydrate field has come to be known as more scientists and engineers on gas hydrate investigation and research. A suite of well constrained short-term production tests by depressurization and thermal-stimulation techniques were undertaken and successful on the Mallik 2002 Gas Hydrate Production Research Well Program, which confirms the feasibility of natural gas production from gas hydrate. The Mallik 2002 Program is a milestone in gas hydrate exploitation, which has provided a basis for future long-term production test and production strategies. It is believed that the potential of gas hydrate as an energy source is likely become as an energy commodity in the future.
