全球致密砂岩气资源分布特征与规律

Distribution Characteristics and Regularities of Tight Sandstone Gas Resources in the World

致密气已成为全球非常规天然气勘探开发的重要领域之一,特别是美国致密气大规模开发利用,推动了许多国家进行致密气勘探开发的进程。从全球致密气盆地分布情况入手,对致密气盆地的盆地类型、沉积环境、源岩岩性、源岩成熟度、储层埋深等特征进行了系统研究。研究表明全球致密气资源丰富,分布范围十分广泛。目前,全球已有美国、加拿大、澳大利亚、墨西哥、委内瑞拉、阿根廷、印尼、中国、俄罗斯、埃及、沙特等十几个国家和地区已进行了致密气藏的勘探开发。其中,美国和加拿大在致密气资源勘探开发方面处于世界领先地位。

Tight gas has become one of the most important fields of unconventional gas exploration and development in the world. In particular,the large-scale development and utilization of tight gas in the United States has promoted the exploration and development of tight gas in many countries. Based on the distribution of the tight gas basins in the world,the basin type,including sedimentary environment,source rock lithology,source rock maturity and the reservoir depth of tight gas basin are systematically studied. The research shows that the global tight gas resources will be abundant. The distribution range is very extensive. At present,many countries,such as the United States,Canada,Australia,Mexico,Venezuela,Argentina,Indonesia,China,Russia,Egypt,Saudi Arabia and other countries and regions,have carried out the exploration and development of tight gas reservoir.Among them,Canada and the United States are in the leading position in the exploration and development of tight gas resources.
