即使中国己全力以赴的发展常规油气和致密油气,其产量与需求间仍有着日趋扩大的差距、缺口,在这种背景下进一步实现油气开发多元化显得尤为重要。在中国油气发展战略上应常规和非常规并重,在非常规油气中作为最现实的主攻方向是致密油气、页岩油气和煤层气,业内对此似乎无大争议。但进一步说,非常规油气三者中孰先孰后却分歧不小。把问题敞开来,实质上是对中国煤层气、页岩油气的前景怎么评价,对中国油气形势的严峻性以及中国油气发展战略的争论。
Even though China has devoted all its efforts to the development of conventional oil and gas and tight oil and gas, there is still an ever-widening gap and gap between output and demand. It is even more important to further diversify oil and gas development in this context. It is not controversial in the industry that there should be both conventional and unconventional strategies in China’s oil and gas development. As the most realistic main thrust in unconventional oil and gas are tight oil and gas, shale oil and gas and coalbed methane. But further, unconventional oil and gas among the three before the divergence is not small. To open up the issue is essentially an assessment of the prospects of coalbed methane and shale gas in China, the severity of the situation in China’s oil and gas and the controversy over China’s oil and gas development strategy.
