Desander

🌪️ Downhole Drilling Desander | High-Efficiency Solids Control Equipment

The Downhole Drilling Desander is a key component of the drilling solids control system, designed to efficiently separate sand and abrasive particles from the drilling mud. Installed on top of the mud tank, the desander works right after the shale shaker and vacuum degasser, but before the desilter, forming the second stage of solids control.

This system removes solids in the 45–74-micron range, protecting downstream equipment, extending mud life, and improving drilling efficiency.

⚙️ Product Overview

The Downhole Drilling Desander operates on the principle of centrifugal separation.

Unprocessed drilling mud is fed into the desander cyclone cone under pressure through a horizontal inlet.

The heavier solids are forced to the cone wall and discharged through the underflow, while the cleaned fluid flows out from the overflow outlet to the next treatment stage.

Optionally, a bottom shaker can be integrated to collect separated solids from the cone nozzles for easy disposal.
