In traditional fossil energy, natural gas is relatively clean energy. In natural gas, unconventional natural gas (dense gas, coalbed methane, shale gas, natural gas hydrate) has change the energy structure and pattern of the enormous potential.
Unconventional natural gas resources development and utilization in China started late, development is not balanced, the economy overall is poor. Dense though gas has realized using scale development, but the resources quality overall deviation, at present the disposable rate is low. CBM primarily achieved commercial exploitation, but high efficiency, low cost development technology is not mature. Shale gas is just beginning to industrial pilot test, for geology and engineering conditions are complex, and the key technology has not yet breakthrough. Natural gas hydrate in basic research and resources investigation stage. According to ?
The main body of the industrial development. The annual production of 2020 is accounted for half of China's natural gas production, 2030 years of total output is about two thirds of the will, in the protection of national energy safety and improve the energy structure in a very important strategic position.
The preliminary evaluation, in the existing technical condition, coalbed methane gas density and shale gas of exploitable resources total 29 ~ 36 trillion m3.
According to the present situation and technological resources of maturity, the coming 5 ~ 10 years of natural gas development in China is unconventional employment.
By speeding unconventional natural gas resource development and utilization, and conventional gas and imported gas, natural gas in our country a energy consumption structure by the proportion of 2011 to 4.6% in 2030 or so, will be to improve our country's energy structure and energy security ? made important contributions
Judge 2: unconventional natural gas development in our country to take "three steps" route, vigorously pushed forward, to speed up the development. In 20 years time, the unconventional natural gas development become support China's natural gas industry rapid, healthy and stable development of force.
From resources reliability, economy and technology maturity look, deal with different types of unconventional natural gas take different development strategies and measures.
Dense gas reality is best, is the leader of natural gas development unconventional, have the priority to speed up the development of conditions.
Have relatively CBM foundation, have to speed up the development of reality.
Shale gas development prospects light, need the solid work, should bring the resources advantages into production advantage. Through the strengthening work ?
Judge three: policy support and technical innovation is to realize the large-scale development of the use of unconventional natural gas key. Countries should give policy support and guide mechanism, ensure the orderly development of unconventional natural gas healthy development.
1, strengthen mechanism guide, actively promote the unconventional natural gas resources orderly and effective development and utilization. Unconventional natural gas is a newly emerging industry in our country, the division of professional sex is strong, driven innovations of the high, policy effect, suit with the multiple competition and division of labor cooperation mode, actively promote, accelerate development. In the early industrialized Suggestions, moderate let go of unconventional natural gas market access, the introduction of multiple main body of investment, technology innovation development to encourage and foster professional division coordination and service system, speed up the unconventional natural in our country
2, give policy support and promote unconventional natural gas mass development and utilization. Recommendation 2020 years ago, will be unconventional natural gas the study and exploration costs would be deducted from part shall be turned over to taxes, and mineral exploration right and mining right of royalties, appropriate relief enterprise income tax, dense gas and shale gas of new technology, new technology research and development expenses refer to tax preferential policy on coalbed methane.
3 unconventional natural gas fields, pay attention to the engineering technology prospective exploration, encouraging independent innovation, actively promote engineering technology and equipment supporting development. Suggestions added sound important national science and technology plan, increase unconventional natural gas field basic research support, and expand the demonstration project scope of implementation, add some pilot test, solving key technical bottleneck, establish a suitable ? in our country
