摘要
本文通过X射线衍射技术对一些液体作用后的粘土矿物晶格变化作了测定,应用冷冻制样、不镀膜方法对样品处理前后进行对比扫描电镜观察。结合渗透率试验,进行了粘土矿物伤害油气层的研究,并对预防措施作了探索。
In this paper, the crystal lattice change of clay minerals after being acted by some fluids is determined by X-ray diffraction technique. A contrast observation of the samples was done with scanning electron microscope before and after they were treated by using freezing to prepare them and non-coated mtethod. Combining with permeability test, the damage of clay minerals to oil-and gas-bearing formations is studied, and the preventive measures are approached.
