摘要:

四川盆地页岩气已实现勘探开发重大突破,但规模商业开发仅集中在3 500m以浅地区的五峰组—龙马溪组海相页岩气。近期四川盆地页岩气产量能否实现快速增长,关键在于五峰组—龙马溪组深部地区的页岩气能否实现规模商业开发。笔者对比浅层区分析了川南深层区五峰组—龙马溪组深层页岩气地质特征,研究认为:五峰组—龙马溪组虽然为广阔的深水陆棚相沉积,但川南深层区富有机质页岩厚度达120m以上,而涪陵浅层区富有机质页岩厚度在100m左右;2个地区TOC含量及其变化规律相似,优质页岩厚度均在40m左右,但演化程度向川南深层区增加;从涪陵浅层区往西至威远—荣县地区,富有机质页岩硅质含量降低、钙质含量增加;由于溶蚀孔的存在,川南深层孔隙度略大于涪陵浅层;深层页岩气保存条件整体好于浅层,含气性好于浅层,但在盆地边界断层附近和盆地内部变形较强烈局部构造上深层页岩气保存条件变差,含气性变差。四川盆地南部深层页岩气资源潜力大,勘探开发前景广阔。针对川南深层区页岩气有效开发面临的地质、工程技术挑战,提出了加强小层对比评价和构造精细解释、裂缝预测、加强深层页岩气钻完井和压裂技术攻关、加强深层页岩气井高效生产管柱和配套工艺攻关等建议。

Abstract:

Shale gas exploration and development in Sichuan Basin had achieved a major breakthrough.But business development focused only on marine shale gas in shallow layers (vertical depth<3 500m) of Wufeng Formation-Longmaxi Formation.Therefore,business development of deep shale gas (vertical depth >3 500m) in Wufeng Formation-Longmaxi Formation is the key to the rapid growth of shale gas production in the Sichuan Basin.In the literature,authors analyzed the geological characteristics of deep shale gas of Wufeng Formation-Longmaxi Formation in southern Sichuan Basin through particular dissection and analysis of deep wells,comparing with the shallow layers.The thickness of organic-rich shale in deep region of southern Sichuan Basin is more than 120m,which is larger than that of shallow layers in Fuling.The vertical TOC change is the same,and the thickness of high quality shale is about 40m in the two regions,but RO is higher in the deep region of southern Sichuan Basin.The calcareous content of the organic shale increases,and the silicon content decreases from Fuling gas field to the deep region in southern Sichuan Basin.Research shows that the shales in Wufeng Formation-Longmaxi Formation of the southern Sichuan Basin from deep to shallow layers do not have so much differences in depositional environment,lithology,TOC,etc.There are four major differences:the porosity of shale in deep region of Southern Sichuan Basin is higher than that in Fulin because of denudation pore.The gas-bearing properties is better in deep region of southern Sichuan Basin with better preservation condition than that of shallow region in the Fuling gas field,but the gas-bearing property is worse in the local region with stronger structure deformation and the basin boundary fault zone.The shale gas resource in the deep region of southern Sichuan Basin is great and has wide prospects for exploration and development.In order to make breakthrough in deep shale gas commercial development as soon as possible,the authors propose the follow works as:Strengthening evaluation of small layer contrasting,fine structure explanation,fracture prediction;strengthening research of drilling and fracturing technology for deep shale gas;strengthening research of the wells column and supporting technology for efficient production of shale gas.
