New natural gas extraction technology outlines China's new blueprint for energy

in the past two years, the significance of the rapid development of shale gas development in the United States has been increasingly recognized by the world's widely modified technologies: mainly blending, filling, toughening, strengthening, compatibility, flame retardancy, alloying and other technologies. At least in a relatively short period of time, the domestic natural gas market structure of the United States has changed, and the liquefied natural gas market around the Atlantic region has also been deeply affected. This wave of technological progress is expanding all over the world. As the second largest energy consumer in the world, the development trajectory of China's energy production and consumption may also be affected by this development momentum to a considerable extent. The impact on China's energy market usually brings a chain reaction around the world, which is manifested in the energy market, investment flows and carbon dioxide emissions

unconventional natural gas is stored in rock layers with few holes and poor permeability, so innovative technology is required to exploit it. At present, there are three kinds of unconventional natural gas reservoirs that are often exploited: tight sandstone gas, shale gas and coal gas. In the United States, the natural gas fields with the above three structures have been exploited for decades. However, it is only recently that technological progress has led to an increase in shale gas production efficiency, which coincides with the main needle to the extent of low-cost mass production

Another characteristic of unconventional natural gas reservoirs is that gas reservoirs are no longer fragmented pieces, but can cover the whole basin. In other words, whether in North America or other parts of the world, there is the potential to discover large-scale natural gas reservoirs. Current estimates suggest that the recoverable unconventional natural gas reserves may exceed the total proven conventional natural gas reserves. From this, we can conclude that the proportion of natural gas in the composition of world energy consumption will increase year by year in many years to come. In addition, many of the newly discovered unconventional gas fields may be located in regions with huge energy consumption, such as North America, Europe, China and India

there is no free lunch in the world. The exploitation of unconventional natural gas fields by breaking rock strata may bring great challenges to the protection of water resources and the goal of reducing water pollution. Destroying the rock stratum requires a lot of water, and if the defense measures are not in place, the chemicals used to assist in destroying the rock stratum may pollute the water source

the changes that are taking place recently are of great significance to China. First of all, this will exert downward pressure on global natural gas prices, which is a good thing for a large natural gas importing country like China. Second, this will allow China to obtain more sources of liquefied natural gas imports. This can be illustrated by some examples: for example, the joint acquisition of arrow energy by PetroChina and shell is very illustrative. Arrow energy has a large number of CBM mining rights, distributed in India, Indonesia, Vietnam and China

for China, the most important issue is to find out how many unconventional natural gas resources in China may be explored and exploited. In Ordos in the north and Sichuan Basin in the southwest, tight sandstone natural gas reservoirs have been exploited. As early as the 1990s, Chinese energy companies have begun to cooperate with foreign-funded enterprises to develop coalbed methane, which is abundant in coal producing areas in northern China. Due to many technical difficulties, the development of coalbed methane mining has been slow. The exploitation of oil shale natural gas in China is still in its infancy

the future development of China's unconventional natural gas industry also faces many problems, the most important of which is the geology and the selection of suitable fixtures and clamping blocks for assembly. How large will China's potential natural gas production be? How about the quality? How long does it take to improve mining technology to achieve low-cost large-scale development and utilization of these resources? The answers to these questions depend on the geological structure of natural gas, the degree of cooperation between Chinese companies and international partners, and the pricing level of the domestic natural gas market. All these factors are difficult to predict. At present, the only thing the government can directly control is the price of natural gas. The Chinese government also needs to balance the interests between natural gas producers and consumers

Another important management problem that the government needs to face is how to strictly monitor and control the use of water resources, reduce water pollution and avoid environmental damage. In many densely populated areas of China, water resources have been seriously scarce and of low quality. The development of unconventional natural gas fields will put greater pressure on the regulatory capacity of the Chinese government

there will also be some problems in energy policy. Will the increased production of unconventional natural gas fields in China be used to replace imports and reduce the energy dependence that has great advantages in foreign design and sustainability, or just as a supplement to imports? This policy choice has a significant impact on China's potential natural gas supply. This will also affect the pace of building a low-carbon economy in China. If China is committed to improving its energy self-sufficiency and national energy security, it is likely to impose restrictions on imported natural gas and rely more on domestic coal and natural gas. Another noteworthy question is whether the new domestic natural gas supply channels will make the government consciously or unconsciously relax its efforts to improve energy efficiency

finally, the process of exploring and exploiting unconventional natural gas fields in China will require state-owned oil companies to invest a lot of money and management costs. After the recent rapid expansion of overseas business, maybe they will consider appropriately reducing the investment in the international market and concentrating human and financial resources to carry out the exploration of unconventional natural gas resources in China
