n: See API filtration.

n: A very important target. The lower the filter loss of drill fluid, the more steady the borehole face is.

n: Control three aspects of drilling fluid: 1) density controlling;2) viscosity and shearing force controlling;3) filter loss controlling.

n: the physical and chemical characters of the drilling fluid including density, viscosity,shear force,filter loss,sediment charge,PH value and so on

n: the amount of fluid that can be delivered through a permable filter medium after being subjected to a set differential pressure for a set length of time.

n: the liquidoid qantity in drilling fluid ,penetrateing into the formation

n: the additive used to reduce the filter loss of dirlling fluid

n: the sticking that because the property of drill fluid is not good, causing layer is became slack because of too much filter loss,or the argillutite swelled because of the hole section which angle of bedding are too large stripping into the well.

n: mud fluids filter loss is very large, free water seeps into unconsolidated formation resulting in layer swelled.

n: a kind of invert oil mud whose filter loss is 8-12ml under high temperature and pressure and whose content of liquid phase and colloid is low

n: a kind of sealing slurry with high solid content and high filter loss,made from inactive substance and bentonite and when injected into the leaking layer the solid will dehydrate at once so as to pack the leaking formation
