应用水平分支井技术开采盐硝的可行性分析

摘要

Currently, during the saltpetre exploitation, the quality of brine is reducing in some saltpetre wells which have been already exploited for a long time. To enhance the brine quality, we can drill some horizontl multilateral wells in the construction of nearby saltpetre horizontal connected wells. This method can increase the controll area of saltpetre wells on saltpetre mineral reserves, and at the same time, improve the brine quality. According to the analysis of difficulties of applying horizontl multilateral wells on saltpetre wells, this paper presents a preliminary study to apply some similar wells in the future.%目前在盐硝开发中，一些开发时间较长的盐硝井，卤水的品质也逐步的在降低，为了使卤水品质提高，可以在附近盐硝水平连通井的施工中，钻水平分支井与之连通，增大盐硝井对盐硝矿藏的控制面积，提高卤水质量，本文通过对盐硝井中应用水平分支井的难点进行分析，为今后实施类似井开展前期研究。
