Tight gas and coalbed methane have become the key areas of global unconventional natural gas exploration, tight oil has become a bright spot in global unconventional oil exploration, and shale gas has become a hot spot in global unconventional natural gas exploration. Global unconventional oil and gas exploration and development have made great progress and strategic breakthroughs. North America, in particular, accounts for 27.2% of the world's natural gas production and has become the world's largest natural gas producing area. The development of unconventional natural gas in the United States has developed rapidly, and the proportion of unconventional gas production has reached 50%. The total production of natural gas in the United States exceeded 6000×10 8 m 3 in 1970, and reached a peak of 6400×10 8 m 3 in 1973. The production continued to decline in the following 20 years, and the total production in 2009 reached 6000×10 8 m 3 , mainly unconventional natural gas. contribution. Its first breakthrough was tight gas, followed by coalbed methane, and then shale gas.
