简介：洗水闭路与洗水平衡在选煤厂的生产中占据着重要的位置，随着科学技术的发展，人类对环境的认识正在逐步提高，洗水平衡与洗水闭路循环已经成为每一个选煤厂所必须解决的课题，其所耗费用在选煤生产经营成本中所占的比例也逐年增加。在这一方面，国内外虽有很多先进的经验值得我们借鉴，但运用到我们实际生产当中，总有一些不尽如人意的地方。

简介：通过对气井生产系统分析，总结出采气、集输之间存在一定数量关系，以生产过程中气井各节点压力变化的参数为依据，建立数学模型，模拟分析各生产环节，建立完整的系统构成模型。通过对气井流入、流出段分别模拟预测，实现气井生产系统的优化、合理确定气井的动态特性以及分析生产过程中遇到的实际问题。
