摘　　要：本文通过对盐硝井水溶开采矿层溶解速度上升过快的问题进行了系统研究,建立了一套盐硝开采以多井少注,降低注水强度,有计划周期性的倒井,定期定量注油的方案,稳定盐硝水质量,延长盐硝井服务年限,有效提高矿产资源采收率。通过研究,取得一系列重要成果和认识,对该区盐类矿床的勘探开发生产具有重要的指导意义。In this paper,through the systematic research on the problem that the dissolution rate of salt and nitrate well water dissolving mining layer rises too fast,a set of salt and nitrate mining scheme is established,which is to reduce the water injection intensity,to pour wells periodically and to inject oil regularly,so as to stabilize the quality of salt and nitrate water,extend the service life of salt and nitrate wells,and effectively improve the recovery of mineral resources.Through the research,a series of important achievements and understandings have been obtained,which has important guiding significance for the exploration,development and production of salt deposits in this area.
