What is a filter cake?
The cake filter is a deposit that is created over time on the filter surface because the particles are captured because they cannot pass the filter. Finally, the accumulation can prevent smooth operation of the filter, as only a minimum amount of liquid will be able to pass for filtration. At this point, the filter cake must be rinsed or removed. For a one -off filter, the technician can dispose of the filter and replace it as soon as it is no longer functional. Drilling of mud and other media passes filters on the way to and through the well and can leave undesirable deposits over time. These can potentially cause problems with lines in the well, slowing or stopping production.
One of the problems in this industry is to create a sticky polymer gel in a filter cake. These can act as an adhesive to force the material to hold the filter, and also to create an impermeable mass. The drilling liquid cannot pass by accumulation and the line is effectively blocked until it can be removed. Some systems may allow them to pervertThe flow was forced by the filter cake by exerting pressure from the other side. In others, it is necessary to manually remove the chemical treatment to break the cake.
companies that produce drilling mud and filters perform testing to learn about the properties of the filter cake of the liquids. If the material causes fast accumulation, it may not be suitable for drilling. They look at how quickly the storage of particles evolves and to the level of permeability. If a layer of debris is highly permeable, it may allow you to pass fluid and may not be a significant problem in Drilling Metibe. The company can take note of these qualities and discuss them in technical specifications to inform users about any problems they can experience.
Such accumulation of material can also occur with other types of filters. Because the filters are often not easy to see, operators can only estimate the amount of filter cake present on the basis of changes in filtration speed and other problems. NoWhich systems use warning light to indicate where the filter is introduced for too long, so operators know to check the filter and clean or replace it if necessary for a specified period of time.
