  Desanders and desilters are core equipment in a solids control purification system, directly affecting the efficiency of drilling fluid purification and overall operational performance. They are widely used in various slurry treatment applications such as oil and gas drilling, trenchless construction, and slurry shield tunneling projects. Desander and Desilter: Core Classification Units in the  Solids Control System The desander is the second solids control device in the solids control system and is also referred to as the third-stage purification equipment. The desilter is the third solids control device and is also known as the fourth-stage purification equipment. In the system layout, the desander is installed after the shale shaker, while the desilter is installed after the desander. In theory, the desander removes solid particles sized 45–74 microns, while the desilter removes particles sized 15–44 microns. In oil and gas drilling mud systems, the common hydrocyclone ...

  In a drilling mud solids control system , the shale shaker, desander, and desilter complete the step‑by‑step separation of large, medium, and fine particles in the early stages. However, to achieve deep purification of drilling fluid, remove ultra‑fine harmful solids, and recover barite, a centrifuge is indispensable. As the fine‑separation unit at the end of the solids control system, th e mud decanter  centrifuge undertakes the critical task of micron‑level particle separation and directly affects drilling fluid performance, drilling efficiency, and overall operating costs. Introduction to Mud Decanter Centrifuge The Mud Decanter centrifuge is the fourth solids control device in a solids control system and is also referred to as the fifth stage purification equipment. The most common type used is the horizontal  mud decanter centrifuge. It is installed downstream of the desilter or mud cleaner. Mud Decanter Centrifuges are designed to process solid particles ranging f...

  As a key secondary purification equipment in the drilling solid control system , the vacuum degasser is indispensable for high-risk working conditions such as deep wells and gas wells, ensuring drilling safety and improving mud quality. Definition & Core Functions Installed after the shale shaker, the vacuum degasser is designed to remove micro-bubbles (≤3 mm) in drilling fluid (while liquid-gas separators handle bubbles ≥3 mm). Its core functions are: Remove micro-bubbles to ensure stable operation of subsequent solid control equipment .   Reduce concentrations of toxic gases (e.g., methane, hydrogen sulfide) to enhance on-site safety   Adopt a liquid ring vacuum pump for negative pressure mud suction, no additional mud supply pump needed Main Structure Types 1. APZCQ Integrated Standard Type (Best-selling) .   Features: High efficiency, stability, no transfer pump required, mature and reliable. Main components: Tank body, internal impeller, motor, belt, vacu...

  Shale shaker s are one of the most critical pieces of equipment in a drilling solids control system and are also the first to operate in the entire process. As the primary (first-stage) solids control equipment, shale shakers run throughout the whole drilling operation and play a decisive role in mud performance control and the stable operation of downstream equipment. Position of the Shale Shaker in the Mud System The shale shaker is the first-stage solids control unit, mainly used to remove solid particles with a size of ≥74 microns from drilling fluids. During drilling operations, the shale shaker operates continuously, separating large cuttings and harmful solids at the earliest stage. Under normal conditions, the mud fed to the shale shaker comes from: - Drilling fluid overflowing from the wellhead into the flow line tank / buffer tank, and then flowing onto the shaker screens; - When there is a potential risk of well kick and a mud gas separator is put into operation, the m...
