山东省地下卤水资源开采潜力分析

Pontentiality Analysis on Uderground Brine Resources in Shandong Province

摘要:

山东省地下卤水分布在环渤海和胶州湾沿岸，总分布面积约3003.11km2，总静储量（333+334）807734.3m3，总可开采量28721.9m3/a。卤水资源的开采主要集中在莱州湾南岸的寿光市、寒亭区、昌邑市、莱州市，黄河三角洲的沾化县、东营区和广饶县，开采利用的均是埋藏深度在100m以浅的卤水资源，主要用于提取原盐和溴素，2008年卤水开采量31697.9万m3/a。由于卤水资源开采程度的不同，在部分地区形成了超采区，形成了地下水降落漏斗。采用开采潜力系数法将将卤水分布区分为有潜力区、采补平衡区和超采区。

Abstract:

Underground brine in Shandong province mainly distributed in Bohai Sea and Jiaozhou Bay coastal areas. The total distribution areas are about 3003.11km2, total static reserves （333+334）is about 807734.3m3, and total recoverable amount is about 28721.9m3/a. Exploitation of brine resources mainly concentrated in south bank of Laizhou Bay, such as Shouguang city, Hanting district, Changyi city, Laizhou city, and the Yellow River Delta as Zhanhua county, Dongying district and Guangrao county. Development and utilization are shallow brine resources buried within 100m. It is mainly used for extracting salt and bromine. Brine extraction amount is about 31697.9×104m3 in 2008. Due to the different levels of brine exploitation, overexploitation areas have been formed in some areas, and formed groundwater depression cone. Using exploitation potentiality coefficient method, brine resources distribution area have been divided into potentiality area, balanced area and over exploited area.
