有了合适的造浆粘土,并不等于就一定能配制出好的钻进泥浆.如果用法不当,不但粘土用量大,使泥浆成本增高,而且配制的泥浆质量满足不了生产需要,反而影响钻探施工.我们在造浆粘土鉴定工作中,针对内蒙岩芯钻探使用造浆粘土中存在的问题,着重对粘土的颗粒度、预水化、碱处理等方面的问题进行了实验研究. 提倡使用粘土粉“就地取材”,不经加工,而把原土直接供给机场使用的简单做法,目前仍被一些野外队采用.这不仅使泥浆不好搅拌,更重要的是不能充分发
With appropriate clay, does not mean that will be able to formulate a good drilling mud.If improper use, not only the amount of clay, mud costs increase, and the preparation of mud quality can not meet the production needs, but affect the drilling construction In the appraisal work of clay for clays, in order to solve the problems existing in the use of clay in drilling in Inner Mongolia, we focus on the experimental research on clay particle size, pre-hydration, alkali treatment, etc. We advocate the use of clay powder The simple method of “directing raw materials into the airport without processing” is still used by some field teams, which not only makes the mud mix poorly, but more importantly, it can not be fully developed
