China’s Desilter Performance

Recent years have seen progressive roll-out and application of China’s mud purification system in different drillings, leapfrog development/great strides in manufacture techniques and theoretical researches, especially the latter one extending to shale shaker’s structural principle, desilter’s structural principle, etc, which have gone near to or reached the world’s frontier, but still some distance to parallel the other countries in performance and lifespan. The common set in China referring to double shale shaker and a single desander rarely with another desilter, produced less than ideal and under-exploited mud performance, reduced efficiency and wasted the mud. Then desilter was gradually developed.

Other Countries’ Desilter Performance

It is well represented by U.S. Baroid, Brandt, Sweco and so on because of their first-tier quality, function and higher standardization, serialization as well as customization. Their latest upgrading transformations in the design are mainly reflected on the driving mode of fine-mesh high-frequency shale shaker, tensioning mode of screens, cross-section shape of cyclone’s inlet passage, materials for upper, lower cones and lining, etc, and have been widely applied for better purification and stabler performance.

At present, it is essential to equip every deep-water mud purification system with desilter and it is imminent to conduct more R&Ds of the vital part face with year-on-year increase of drilling rigs in China.
