页岩气发展现状及勘探前景

The development status of shale gas in the world and its exploration prospect in China

随着北美地区页岩气勘探的巨大成功,页岩气资源勘探在全球范围内持续升温,现已有10多个国家开展了页岩气的勘探与开发试验工作。研究认为,中国页岩气资源丰富,许多盆地或地区具有页岩气大规模成藏的地质条件,中国的南方地区、华北-东北地区、西北和青藏地区都具有良好的页岩气勘探前景。通过分析比较上述地区页岩气成藏主控因素后认为,中国的南方、西北(包括鄂尔多斯盆地及其周缘)和青藏地区都是比较有利页岩气勘探区域,其中南方地区应作为中国实现页岩气勘探突破的首选地区。中国的页岩气勘探目前还处于起步阶段。

With the great success of shale gas exploration in the North America,shale gas exploration is warming up all over the world. By now,more than 10 countries have carried out shale gas exploration and development trials. Research suggests that the shale gas resources are rich in China,including the south region,the north-northeast region,the northwest region and the Qinghai-Tibet region which present broad prospect for shale gas exploration. Through analysis and comparison of the controlling factors of shale gas accumulation,it shows that China's south region and northwest region (including the Ordos Basin and its margins) and the Qinghai-Tibet region are more favorable for shale gas exploration. And the south region should be the first choice to achieve a breakthrough for China’s shale gas exploration. Shale gas exploration in China is still in infancy stage.
