介绍了一种用于定量评价水基钻井液滤失特性和外部滤饼破裂行为的新型装置。在静态过滤下，过滤压力（400至800 kPa），时间（15至60分钟），增重剂的粒度分布（D50：11至136 µm）相对于基材的孔径分布（S50：14和65 µm）和增重剂类型（CaCO3或BaSO4）在控制滤饼的孔隙率、厚度和抗破裂性方面起着重要作用。随着泥浆D_（50）的增加，无论外部滤饼厚度如何增加，标准化抗破裂阻力都会降低约20%。此外，滤液的粘度随着D50增加，表明滤饼中保留较少的黄原胶。密度较大的重晶石颗粒形成较薄且较紧的块，其表现出较高的抗破裂性。
A novel apparatus is used to quantify the filtration characteristics of water-based drilling fluids and rupture behaviour of external filter cake. Under static filtration, the filtration pressure (400 to 800 kPa), time (15 to 60 min), the particle size distribution of the weighing agent (D50: 11 to 136 µm) relative to the pore size distribution of the substrate (S50: 14 and 65 µm) and the type of weighing agent (CaCO3or BaSO4) play an important role in governing the porosity, thickness, and the rupture resistance of filter cake. With an increase in D50of mud, the normalised rupture resistance reduces by about 20% irrespective of the increase in the external filter cake thickness. Further, the viscosity of the filtrate increases with D50indicating the retention of less xanthan gum in the filter cake. The denser barite particles form a thinner and tighter cake, which exhibits higher resistance to rupture.
