TMC的室内配方研究

Study on MTC Labortory Composition

钻井液转变成水泥的技术简称ＭＴＣ技术。本文选用自制的分散剂Ｆ－２，有机缓凝剂，早强剂及激活剂进行了大量的ＭＴＣ配方筛选。不同的温度条件下，在室内成功地进行了ＭＴＣ转化。经辽河现场泥浆验证表明：该配方使转化后水泥石三天强度大于１０ＭＰａ，流变性。

The technique of the conversion of drilling fluid into cement is called MTC technique for short.In this paper,the self-made dispersant F-2,organic slow dilution agent,early strength agent and activator are sieved by MTC composition.MTC is successfully converted in laboratiory at different temperature.The in-situ mud test in Liaohe Oil Field shows that due to the composition,the strength of the converted cementstone is greater than 10 Mpa in three days,and its rheological property and viscosifying time can satisfy the requirements of cementing.
