摘要

陕北奥陶纪盐田是目前我国发现的规模最大的盐田 ,它不但构造简单、埋深适中、盐层厚度大、分布稳定、资源量丰富、石盐质纯、盐质好 ,而且附近有优质洁净的煤炭和电力资源长期供应 ,是进行盐矿开发和发展盐下游化工产品的有利地区。长庆油田等单位 ,在对数十个钻孔进行岩性地质编录的基础上 ,应用数字测井、高分辨率地震勘探和对应的高精度岩性解释技术 ,基本查明了马五 4、马五 6盐组石盐的时空展布和石盐矿石中NaCl化学成分的变化规律 ,对矿石进行了加工性能实验 ,在盐田勘查程度较高的地区计算石盐内蕴经济储量 8854 55× 1 0 8t,为陕北奥陶纪盐田的开发奠定了基础
The Ordovician salt field is the largest one found in China so far. It is characterized not only by its simple structures, moderate buried depth, salt layers thick, stable distribution, abundant salt resources, pure and good quality, but also by high quality and pure coal and electric power supply for long term. It is a favorable district for salt development and by products of salt. Based on lithological and geological documentation in several tens of boreholes, digital logging, seismic exploration with high resolution and lithological interpretation with high precision, the space distribution and the changes in chemical components (NaCl) of halite are examined in salt group of halite Mawu 4 and Mawu 6. The experiment has been done for processing function of ores. It has been calculated that the economic reserves of halite in the paces explored with higher level are 8,854 55×108 t.
