【摘要】：“內(nèi)蒙古自治區(qū)額濟(jì)納旗策克口岸水資源評價與預(yù)測分析研究”目的任務(wù)是：為了滿足策克口岸發(fā)展規(guī)劃的需水要求,在策克進(jìn)行水文地質(zhì)勘查工作,研究其水文地質(zhì)條件,初步查明地下水分布規(guī)律,查清地下水、地表水資源量,尋找富水地段,提出各類水的合理配置,為口岸區(qū)合理開發(fā)利用水資源提供依據(jù)。工作起止時間2008年10月至2009年12月,野外完成鉆探3670.98m。本次工作基本查明了工作區(qū)北部白堊系承壓含水層的水文地質(zhì)條件,對白堊系承壓含水層的空間結(jié)構(gòu)、巖性、厚度、水位、水量的分布變化規(guī)律、地下水補給、徑流、排泄條件及地下水動態(tài)特征和水化學(xué)條件進(jìn)行了敘述,為地下水資源評價奠定了基礎(chǔ)。并確定其靜儲存量為58.82億m3,承壓水的彈性儲存量為414.42萬m3,天然補給量為194.50萬m3/a,地下水消耗量為183.69萬m3/a,地下水允許開采量為182.5×104m3/a。該含水層主要巖性為泥質(zhì)砂礫巖、砂巖,厚度35.57-105.31m。水位埋深+6.63-57.13m,滲透系數(shù)0.19-6.54m/d,單井涌水量227.48-628.85m3/d,礦化度1.10-1.15g/L,氟離子含量0.1—2.4mg/L,水化學(xué)類型以Cl.SO4-Na為主。在靠近口岸附近圈定了相對富水地段,選擇了水源地。為口岸區(qū)合理開發(fā)利用水資源提供了依據(jù)。
[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.
