水基钻井液配浆剂纳米化途径和表征方法

钻井液体系正电化、纳米化、方便化是钻井液技术的发展趋势之一。聚合物／层状粘土纳米复合材料的制备是目前国内外纳米材料研究领域中的重点之一，并已经取得了重要突破。通过研究认为，纳米水基钻井液配浆剂，怍为聚合物／层状粘土纳米复合材料，已经有原位聚合法、溶液插层法和熔体插层法比较成型的方法可供借用。结合纳米水基钻井液配浆剂的具体特点，认为以熔体插层法为基本内容的挤压成型法，简单易行，综合成本较低，可在常规的挤出机等加工设备上直接进行，是目前制备插层型聚合物／粘土纳米复合材料的主要方法，熔体插层法不需要任何溶剂、工艺简单，易于工业化应用，对环境优化。对于纳米水基钻井液配浆剂性能的表征，X射线衍射法、TEM法和Malvern激光测粒仪法是最常见的方法。

Nanometering Way and Characterizing Method of Water Base Drilling Fluid Materials

Preparation of Nanometer compound materials of polymer-layered bentonite is one of the important aspects in the area of research of nanometer materials today. It is known by the information investigation that as nanometer compound materials of polymer-layered bentonite there have been already created inherent polymerization method, solution layer inserting method and melt layer inserting method in the field of preparation of making-up materials of nanometer water base drilling fluid. By analyzing all these methods, it is rational to consider that the method of pressing-modeling is the industrial method of cost saving and easily conducted by using regular mechanical press equipment as it does not need melt and its simple technology compared with melt layer inserting method as well as it does not have negative effect on environment. For characterizing making-up materials of nanometer water base drilling fluid, X-ray diffraction, TEM method and Malvern particle size laser analysis are the broadly applied methods.
