准噶尔盆地古尔班通古特沙漠地区水文地质特征及对石油开发的建议
|
摘要
古尔班通古特沙漠地下水类型包括松散岩类孔隙潜水和碎屑岩类孔隙裂隙承压水,其潜水资源富水性极弱,不具开发条件;承压水厚度较大,分布范围广,补给量比较稳定,具有一定的开发潜力;承压含水层总厚度较稳定,由北向南、由西向东逐渐变薄;渗透系数较低,整体由北向南、由西向东逐渐变大;富水性整体中等;径流速度小,运移迟缓,地下水水质较差,整体由东向西、由南向北逐渐变大。承压含水层从根本上解决了区内石油开发的用水问题,起着至关重要的作用,在地下水开发的同时,必须重视地下水资源的安全问题。
The distribution of Gurbantunggut Desert groundwater include the loose rock pore phreatic water and clastic rock fracture pore confined water,Phreatic water resource is very weak,don′t have the conditions for Developmen.Big thickness, wide distribution, supply is relatively stable about the confined water has certain development potential,it′s thickness is relatively stable, from north to south, from west to east gradually thin, low permeability coeffi-cient, overall from north to south, from west to east gradually become larger, watery whole medium, run off velocity,migration and retardation, groundwater quality is poor, the overall from east to west, from south to north gradually larger. Confined aquifer is the fundamental solution to the problem of water about oil development,in the groundwater de-velopment and at the same time, also must pay attention to the safety.
