阿尔金山南缘中侏罗统页岩气有利区优选与资源潜力
Favorable area selection and resource potential of the Middle Jurassic strata on the southern Altyn Tagh Mountains,NW China
摘要
Abstract
The shale characteristic of Dameigou Formation within southern margin of Altyn Tagh Mountains,such as organic matter abundance,thermal maturity,gas bearing capacity and preservation condition,have been analyzed based on geological background,shale distribution characteristic and the fundamental data of field outcrop,well core and typical cross section.In combination with structural environment and burial depth conditions of shale within target formation,No.1 Mangya,Qingshui River,Heishi Mountain and Yueya Mountain four favorable areas of shale gas have been selected.The total effective exploration areas of four favorable areas are 1 692.54 km2.According to some key evaluation parameters such as shale area,thickness of shale,density and gas content,the potential of shale gas resources have been evaluated.The total P50 resources are 4 514.41× 108 m3,which contain 723.05×108 m3 of No.1 Mangya favorable area,1 845.10×108m3 of Qingshui River favorable area,199.10 × 108 m3 of Heishi Mountain favorable area and 1 747.16 × 108 m3 of Yueya Mountain favorable area.Four favorable areas mentioned above show huge shale gas resources potential.关键词
