Our shale gas reserves, although large, proppant supplier but the impression by the terrain conditions, technical and economic and other factors, the development extremely difficult. High water consumption and environmental threats become shale gas development on the road of the "stumbling block", which makes part of the project has been mined shale gas is not as expected in the well. Each country is different according to their own circumstances Looking endowment policies for the development of shale gas balance, while China, how will it?
Shale gas is a very huge resource potential of unconventional oil and gas resources, has long been affected by many factors, technical, economic, and its development has been relatively slow.
China shale gas resources as one of the richest countries, the development of shale gas resources is also considered to enhance China's natural gas supply capacity, an important way to "cut coal enlargement of gas," national energy strategy. However, to achieve this goal is no easy task, the upstream development of environmental issues will be restricting large-scale shale gas, a key factor for sustainable development. Investment Advisor Director Guo Li pointed out that China shale gas reserves, although large, but the rugged terrain, poor infrastructure and deeper shale gas layer also makes the development very difficult, and preliminary exploration of shale gas development investment, investment high-risk, long payback period, is heavily dependent on pipeline construction and other characteristics also makes its liquidity the ability to develop business requirements are relatively high.
High water consumption and environmental threats become shale gas development on the road of the "stumbling block", which makes part of the project has been mined shale gas is not as expected in the well. On the one hand, horizontal drilling and hydraulic fracturing method is the core technology for shale gas, but fracturing mining requires large amounts of water, even if flowback achieve a higher rate, it will reach the water consumption of conventional natural gas 10 times the sustainable use high density ceramic of water resources for the local impact, water consumption restricted the bottleneck of shale gas development; on the other hand, shale gas development also faces environmental problems, due to the need to page in the mining process rock fracturing fluid injected into the high contain chemical reagents, but if inadvertently penetrate into the ground or spills with the rainy season, can easily result in contamination of the local groundwater quality in shallow and, in addition, shale gas extraction process also produces noise, exhaust gas as well as environmental pollution caused by mining accidents disaster.
