中国页岩气勘探开发进展与发展前景

Progress and prospects of shale gas exploration and development in China

全球掀起了轰轰烈烈的"页岩气绿色革命",北美以外地区有20余个国家在进行页岩气前期评价和勘探开发先导试验,页岩气资源成为潜力较大、较重要的天然气开发目标。中国发育海相、海陆过渡相—陆相煤系和湖相3类富含有机质页岩,都具备页岩气形成与富集条件,页岩气资源丰富。中国在页岩气资源潜力评价和勘探开发先导性试验上取得了重要进展,正在寻求实现页岩气资源有效开发。本文系统总结了中国页岩气勘探开发实践,分析了中国页岩气资源前景,指出中国页岩气资源丰富。目前已在中国多处发现了页岩气资源,发展前景良好。与北美相比,中国页岩气形成与发展具明显的特殊性,许多地质与开发难题亟待解决。随着页岩气地质评价与开发理论创新及相关关键技术突破、经济条件改善和国家政策支持,未来中国页岩气资源发展前景广阔,有望改变中国天然气发展乃至整个能源发展格局。

A global astounding ＂shale gas green revolution＂ is booming. More than 20 countries except for the North America are con- ducting prophase evaluation and pilot test of shale gas exploration and development. Shale gas resource has already become a natural gas production target with great potential and of great significance. There are three types of organic-rich shale developed in China, including marine, marine-continental transitional facies-continental coal series and lacustrine facies. These types of shale all have shale gas formation and enrichment conditions, so the shale gas resource is abundant. China has made important progress in the po- tential evaluation and pilot test of exploration and development of shale gas resources and is seeking for a means to effectively develop shale gas resources. This paper systematically summarizes China＇s shale gas exploration and development practice and analyzes shale gas resource prospect. On this basis, it points out the development prospect is promising thanks to that the shale gas resources are not only rich, but have been praetieally found in many places in China. Compared with the North America, formation and develop- ment of China＇s shale gas have obvious particularity and many geological and development problems need to be solved urgently. With innovation of shale gas geological evaluation and development theory and relevant key technology breakthroughs, improvement of e eonomic conditions and national policy support, prospects for development of shale gas resources in the future are broad and expected to change the pattern of China＇s natural gas development and even the whole energy development.
