摘要
页岩气是一种储量巨大的非常规天然气,但是页岩气藏储藏层结构复杂,多为低孔、低渗型,开发技术要求很高,需要大量的技术资金和人员投入。重点介绍了国内外页岩气勘探开发技术,主要包括储层评价技术(测井和取心)、水平井增产技术(多分支井水平井和对接连通水平井)、射孔优化技术以及压裂增产技术;分析了国内在页岩气研究开发中存在的主要问题,指出了当前页岩气开发技术的发展趋势。
Shale gas is a kind of unconventional natural gas with enormous reserves and complex reservoir structure and its development needs high technology,massive fund and a lot of personnel.Mainly introduced are its exploration and development technologies at home and abroad,such as reservoir evaluation technology(logging and coring technology),stimulation technology for horizontal wells(multi-branch and connected horizontal wells),perforating optimization technology and fracturing stimulation technology.Analyzed are main problems which exist in shale gas research and development in China and forecast are development trends of shale gas development technology at present.
