三种冲洗液在不同地层岩心钻探中的应用探讨

Discussion on application of three kinds of flushing fluids in core drilling in different strata

随着我国经济的快速发展,对矿产资源的需求越来越大,有的矿产资源依赖进口,供需矛盾日益突出,为此国家相关部门加大了对矿产资源的勘探与开发力度。钻井冲洗液在矿产资源勘探中发挥着非常重要的作用。本文详细介绍了冲洗液在岩心钻探施工中的作用,在施工实践的基础上,通过钻孔实例总结了三个简单实用、成本相对低廉、采购方便、现场可以制作的冲洗液配方供大家学习参考。

With the rapid development of China s economy,the demand for mineral resources is increasing.Some mineral resources dependent on imports and the contradiction between supply and demand is becoming increasingly prominent.Therefore,relevant national departments have strengthened the exploration and development of mineral resources.Drilling flushing fluid plays a very important role in mineral resources exploration.In this paper,the role of flushing fluid in core drilling construction is introduced in detail.On the basis of construction practice,through drilling examples,the authors summarize three flushing fluid formulas that are simple and practical,relatively low cost,convenient to purchase and can be made on site for your study and reference.
