| 摘 要： | 通过资料调研,分析了页岩气的储层特征:页岩气藏储层中的页岩既是烃源岩也是储层,普遍富含有机质;页岩气藏储气类型以自由气和吸附气为主,吸附气以吸附状态赋存在于酪根和粘土颗粒的表面;页岩矿物组分复杂,渗透率极低,天然裂缝较发育.介绍了国外不同页岩气藏储层压裂改造工艺及相关配套技术;北美页岩气藏开发形成了以水平井完井和分段压裂为主的主体技术,以滑溜水和复合压裂液为主的压裂液体系,以分段多簇射孔、快速可钻式桥塞封隔、微地震裂缝监测和大规模连续混配的配套技术.中国页岩气资源量达20×10(12)-30×10(12)m3,开发潜力巨大,通过了解和学习国外页岩气开发现状和技术,从而加快中国在页岩气成藏理论、构造背景、地质成因、生储盖理论、开发方式、压裂改造技术及相关配套工具等方面的研究步伐,尽快实现中国页岩气的商业化开发. |

| Abstract: | Shale with abundant organic matters is not only hydrocarbon source but storage and conservation in shale gas reservoir, the gas-bearing types in shale gas include free gas and adsorb gas which is adsorbed on surfaces of kerogen and clay.This paper describes the formation characteristics including lithology,permeability and nature fracture and development techniques of shale gas in north America.Shale gas development has experienced vertical completion with small scale fracturing to horizontal completion wit... |
| Keywords: | shale shale gas reservoir segmented and multi-cluster perforation volume treatment simultaneous fracturing |
