页岩气作为一种环保、高效的优质替代能源,各大油企都纷纷跃跃欲试。延长石油从长远出发,积极参与鄂尔多斯盆地页岩气的勘探开发,从2011年开始,延长石油不断引进先进技术、并根据自己的实际情况不断创新,形成了一套自己的勘探、开发技术,包括钻井、压裂、排采、污水处理等。这些新技术不断应用于现场,产生了一定的经济效益,但也产生了不少问题。本文从工程角度说明延长页岩气勘探开发的一些难点,并初步提出一些建议。
As an environmentally friendly and highly effective alternative energy source, shale gas has all been on the upswing. Yanchang Petroleum actively participates in the exploration and development of shale gas in the Ordos Basin in the long term. Since 2011, Yanchang Petroleum has continuously introduced advanced technologies and has continuously innovated according to its actual conditions to form its own exploration and development technologies, including Drilling, fracturing, drainage, sewage treatment and so on. These new technologies continue to be applied to the site, resulting in some economic benefits, but also created a lot of problems. This article illustrates some of the difficulties in extending shale gas exploration and development from an engineering point of view and gives some preliminary suggestions.
