自贡盐场黄黑卤盛衰演变

The Rising and Falling Evolvement of Yellow and Black Brine of Zigong Salt Site

自贡盐场对自流井构造卤水开发利用较早,迄今已二千余年。大量的对深部盐卤资源的开发是在盐井开凿技术的提高和不断完善的基础上实现的,三叠纪地层黄黑卤的开采,使人类进一步开发地下深部资源成为现实。本文通过对自贡盐场近百年(1851～1950年)黄黑卤的开发历史和演变过程做了较为全面、客观的分析和研究,指出自贡盐场黄黑卤在1821～1850年为稳步发展阶段,1851～1892年为旺盛时期,1923年后黄黑卤生产逐渐减小,自贡盐场进入岩盐卤的发展时期。

The exploitation and application of Ziliujing' s brine is over two thousand years. The deep exploitation of brine was realized on the base of improving technique. This paper is a description of exploiting history of yellow and black brine nearly one hundred year (1851 - 1950 ) . After 1923, Zigong salt site entered the period of well salt development because of reducing of yellow and black brine.
