辩证看待中国页岩气开发

Dialectical View of Chinese Shale Gas Development

页岩气是一种清洁、高效的非常规能源,但页岩层较低的渗透率特性,使得对页岩储层的改造成了主要目标,进而开发了水力压裂技术,而水力压裂页岩层是否会严重污染环境引起业界专家学者争议。针对页岩气水力压裂开采工艺,结合现状分析页岩气开采可能造成的水资源的浪费和对环境的污染。文章针对中国页岩气开发初期不完善的相关环境保护制度和尚未完善的技术而言,应重视页岩气开采的环境污染评估,如何高效的开发和对环境的保护,还有中国是否真的适合大力开发页岩气做出分析讨论。

Shale gas is a clean, efficient and unconventional energy source. But the shale has lower permeability, which makes the transformation of shale reservoirs become main goal, so the hydraulic fracturing technology has been developed, and whether or not hydraulic fracturing shale bed will cause serious environmental pollution causes industry experts dispute. Hydraulic fracturing for shale gas extraction process may cause pollution of water resources and the environment. Aiming at the beginning of shale gas development in China, related environmental protection system and technology are imperfect;pollution assessment for the exploitation of shale gas should be paid attention. In this paper, how to efficiently develop the shale gas and protect the environment was discussed as well as the feasibility to develop shale gas on a large scale in China.
