【摘要】：“内蒙古自治区额济纳旗策克口岸水资源评价与预测分析研究”目的任务是：为了满足策克口岸发展规划的需水要求,在策克进行水文地质勘查工作,研究其水文地质条件,初步查明地下水分布规律,查清地下水、地表水资源量,寻找富水地段,提出各类水的合理配置,为口岸区合理开发利用水资源提供依据。工作起止时间2008年10月至2009年12月,野外完成钻探3670.98m。本次工作基本查明了工作区北部白垩系承压含水层的水文地质条件,对白垩系承压含水层的空间结构、岩性、厚度、水位、水量的分布变化规律、地下水补给、径流、排泄条件及地下水动态特征和水化学条件进行了叙述,为地下水资源评价奠定了基础。并确定其静储存量为58.82亿m3,承压水的弹性储存量为414.42万m3,天然补给量为194.50万m3/a,地下水消耗量为183.69万m3/a,地下水允许开采量为182.5×104m3/a。该含水层主要岩性为泥质砂砾岩、砂岩,厚度35.57-105.31m。水位埋深+6.63-57.13m,渗透系数0.19-6.54m/d,单井涌水量227.48-628.85m3/d,矿化度1.10-1.15g/L,氟离子含量0.1—2.4mg/L,水化学类型以Cl.SO4-Na为主。在靠近口岸附近圈定了相对富水地段,选择了水源地。为口岸区合理开发利用水资源提供了依据。
[Abstract]:The purpose of "Water Resources Evaluation and Forecast Analysis of Ceke Port in Ejina Banner, Inner Mongolia Autonomous Region" is to carry out hydrogeological exploration in Ceke Port, study its hydrogeological conditions, preliminarily ascertain the law of groundwater distribution, ascertain the quantity of groundwater and surface water resources, and search for water requirements for development planning of Ceke Port. In the water-rich section, the reasonable allocation of various types of water is put forward to provide the basis for rational development and utilization of water resources in the port area. The drilling time was 3670.98 m from October 2008 to December 2009. The hydrogeological conditions of the Cretaceous confined aquifer in the northern part of the working area were basically ascertained and the spatial structure of the Cretaceous confined aquifer was studied. The distribution and variation of lithology, thickness, water level and water volume, groundwater recharge, runoff, discharge conditions, groundwater dynamic characteristics and hydrochemical conditions are described, which lays the foundation for groundwater resources evaluation. The main lithology of the aquifer is argillaceous sandy conglomerate with sandstone thickness of 35.57-105.31m. The water table depth is + 6.63-57.13m, the permeability coefficient is 0.19-6.54m/d, the water inflow of a single well is 227.48-628.85m3/d, the salinity is 1.10-1.15g/L, the fluoride content is 0.1-2.4mg/L, and the chemical type of the water is Cl.1-2.4mg/L. SO4-Na is the main factor. A relatively rich water area is delineated near the port, and a water source is selected, which provides a basis for rational development and utilization of water resources in the port area.
