摘　　要：为探讨肯基亚克油田盐下油藏8010井井筒的堵塞机理,利用有机溶剂对井筒的堵塞物各组分进行了分离,并利用X射线衍射分析技术分析了无机物杂质的组成。结果表明,盐下油藏8010井井筒主要是由于胶质、沥青质的沉积形成堵塞,该沉积与无机杂质协同作用,加剧了堵塞物的形成。为此,研制出了有针对性的解堵剂配方体系JD-1,该解堵剂体系主要由有机溶剂、表面活性剂以及渗透剂组成。The blocking mechanism in Well 8010 of Subsalt reservoir,Kenjiyak Oilfield,has been studied by separating the components of stemming with organic solvent,and the composition of inorganic impurity is analyzed by X-ray diffraction.The result shows that the blocking in Well 8010 is resulted from deposition of gel and asphaltine,which performs a synergetic effect with inorganic impurity and further intensifies stemming.Accordingly,a block remover system JD-1 is developed,which is composed of organic solvent,surfactant and penetrant.
