摘要
深层地下卤水(包括富钾卤水)是宝贵的液体矿产资源。深层地下卤水在沉积盆地内处于深埋、封闭和高压状态,多呈层状储集和构造富集;无补给资源,不具有可恢复性和可更新性;具有较大的储存资源,不具有调节性。深层地下卤水的开采资源由储存资源转化而来,在开采条件下储存资源逐渐减少趋于衰竭。深层地下卤水的储存资源量可以称为天然(储存)资源量(或远景资源量、潜在资源量),其中在一定条件下能够开采出来的部分称为可采(资源)量,其余为非可采量。可采量可以分为已采(资源)量和尚未开采的剩余可采(资源)量。天然(储存)资源量又可以分为弹性储存资源量和非弹性储存资源量。深层地下卤水资源量还可以分为盆地(区域)的、储卤构造(局部)的和单井的资源量三个层次。
Subsurface brines in deep-seated aquifers(including K-rich brines) are valuable liquid mineral resources.Subsurface brines in deep-seated aquifers in sedimentary basins occur under the deeply buried and sealed state and are of high pressure.The subsurface brines are stored in brine-bearing formations and enriched in brine-bearing structures.The subsurface brines do not have recharge resources and are of no recoverability and renewability.The brine resources have relatively large storage resources and are not regulative.The exploitation resources of the subsurface brines in deep-seated aquifers are transferred from the storage resources.The storage resources decrease and tend to exhaust under the condition of exploitation of the brines.The storage resources of the subsurface brines in deep-seated aquifers can be regarded as natural(storage) resources(or perspective resources,or potential resources).Those of the storage resources,which can be withdrawn under certain exploitable conditions,are called exploitable resources,and the remainders are non-exploitable resources.The exploitable resources include the exploited resources,which have been withdrawn,and the residual exploited resources,which have not been withdrawn.The natural(storage) resources of the subsurface brines are also classified as elastic storage resources and non-elastic storage resources.The subsurface brine resources in deep-seated aquifers can still be classified as resources of three levels of a basin(regional),a brine-bearing structure(local) and a single well.
