Embrace Ultimate Application Challenges of Filtration, Separation, and Purification Technology

Application of completion fluid filtration

 

Completion fluids are used in the drilling area prior to drilling, and well repair fluids are used for in-production well repair, all of which need to be cleaned to avoid clogging the reservoir. Both completion and workover fluids are used to clean the well, remove cuttings, mud filter cake, cement, and control the sand carried by the oil. The function of the filter is to intercept the impurities in the liquid and let the clean liquid return to the oil well.

 

Problems leading to reservoir failure

 

All fluids in contact with the production formation need to be filtered and cleaned, including drilling fluid, drilling fluid, completion fluid, workover fluid, reaming fluid, etc.

Fine impurities entering the oil-producing layer will reduce the permeability of the well hole, thereby reducing the productivity of the well.

 

completion fluid filtration

 

In order to avoid the damage of the oil-producing layer, it is necessary to filter the completion fluid and workover fluid.

The ideal completion fluid is preferably free of any solid impurities. In fact, the goal is to remove particles 5 microns or smaller, which is the most economical.

Stable and reliable oil well fluid filtration can ensure high oil yield and extend the working life of oil wells

In order to prolong the life of the high-efficiency filter element, it is necessary to install a pre-filter before the precision filter to remove large impurities, such as a sedimentation tank, a vibrating screen for removing stones, a centrifugal separator (cyclone separator) and other coarse separation equipment.
