新形势下页岩气开发建设中存在的环保问题及处理技术

Environmental Protection Problems and Treatment Technologies in Shale Gas Development and Construction Under the New Situation

新《环保法》实施以来,在国家环保监管力度加强、相关法律法规深入实施的背景下,我国开发建设规模越来越大的油气田企业所面临的环境问题越来越严重。页岩气开发过程中产生的主要污染物有油基钻井液废弃物、水基钻井液废弃物、压裂返排液等,这些物质会对环境造成严重污染,基于此,形成了处理各类污染物的配套工艺和技术,而解决这些工艺与技术存在的不足将成为我们今后努力的方向。

Since the implementation of the new＂ Environmental Protection Law＂ and relevant laws and regulations, under the background of strengthening supervision and deeply inplemetation of related laws, the environmental problems in oil and gas field development and construction enterprises in our country increasingly large scale facing more and more serious. The main pollutants produced in the proc e ss of shale gas development are the oil base drilling fluid, waste drilling fluid wastes, fracturing fluid, these substances cause serious pollution to the environment, therefore, supporting the formation process and processing technology of all kinds of pollutants, solving the disadvantages of technology will become the direction of our efforts in the future.
