使用API压滤机进行的静态过滤试验已广泛用于评估钻井液滤饼设计方面的过滤性能。然而，该测试没有解决过滤过程的许多方面，如颗粒侵入基材，外部滤饼开始形成的时间以及基材孔喉大小的影响。这是因为API压滤机的设计目的是作为基板滤纸，其孔喉小于钻井液中的固体颗粒尺寸。图中显示，通过对API压滤机的基盖进行简单的修改，可以使用孔喉大于钻井液中固体颗粒尺寸的厚多孔盘。这种简单的变化可以更好地研究和理解过滤过程和钻井液性能。
Static filtration tests carried out by using the API filter press have been extensively used to assess drilling fluid filtration performance in terms of filter cake design. However, this test does not address many aspects of the filtration process such as the invasion of the particles into the substrate, the time the external filter cake starts forming and the effect of the pore throat size of the substrate. This is because the API filter press is designed to use as substrate filter paper with a pore throat smaller than the solid particles size in the drilling fluid. Here it is shown that by a simple modification of the base cap of the API filter press it is possible to use thick porous disks with pore throats larger than the solid particle size in the drilling fluid. This simple variation allows a better investigation and understanding of the filtration process and drilling fluid performance.
