江西省页岩气资源现状与勘探前景

摘要

Shale gas is a clean,efficientofunconventionalgas resources.W ith the breakthrough ofshale gas exploration and developm ent technology, U nited States and C anada develop rapidly in shale gas. O ur country has introduced advanced technology and theory continuously, to prospect dom estic large area shale gas. Through investigation, thinks the low er C am brian,low er Silurian,m iddle Perm ian shale are w idely developed,and have the geologicalconditions of form ing shale gas.C ontrastJiangxiunderlow erC am brian shale w ith dom estic and overseas,getthe conclusion thatJiangxishale reservoir has good geological conditions, great potential for shale gas accum ulation. Shale gas are m ainly distributed in northeast Jiangxi, northw est Jiangxi, Pingxiang-Leping depression and southern Jiangxi, prelim inary estim ates shale gas geology resources ofJiangxiprovince reach up to (3.5~7.0)×1012 m 3.Shale gas resources in Jiangxihave greatpotential,w ith good prospectsforexploration and developm ent.%页岩气是一种清洁、高效的非常规天然气资源。随着页岩气勘探开发技术的突破，美国、加拿大地区页岩气得到迅速发展，我国也在不断引进先进技术与理论，对我国多个地区进行了页岩气的选区和勘探工作。通过调查，认为江西省广泛发育下寒武统、下志留统、中二叠统富含有机质泥页岩系，具备形成页岩气的地质条件。将江西下寒武统泥页岩系与国内外页岩对比，认为江西省页岩储层地质条件较好，成藏潜力大。江西页岩气主要分布在赣东北、赣西北、萍乐坳陷、赣南地区4大潜力区，初步估算了江西页岩气地质资源量在（3.5～7.0）×1012 m 3，认为江西省页岩气资源潜力巨大，具有良好的勘探开发前景。
