Desilter for Oil Drilling Mud System

The desilter is a tertiary solids control device in the drilling fluid solids control system. Its function is to separate solid particles of 15-47 microns in the drilling fluid through the synergistic effect of the cyclone and the vibrating screen, thereby reducing the sand content and improving the stability of the drilling fluid.

To meet increasingly stringent drilling requirements, TR Petroleum Solids Control has extensively optimized its drilling fluid desilters. As a desilter manufacturer for the oil drilling industry, we produce and supply a wide range of desilters, including 4-inch and 5-inch desilters, polyurethane cyclone desanders, cast iron cyclone desanders, oilfield desilters, trenchless engineering desilters, and bottomflow screen desilters.

Drilling desilters are primarily used in oil drilling, natural gas drilling, coalbed methane drilling, shield tunneling, river desilting, and other fields, specifically for mud purification. TR Solids Control can produce desilters of varying specifications to meet the customer's specific processing capacity. These desilters feature a rational structure, a cyclone made of highly wear-resistant composite polyurethane, quick connection, and stable performance.

A drilling desilter consists of a vibrating screen, a diverter manifold, and a cyclone. The desilter is designed based on the principle of sedimentation. The overflow from the cyclone returns to the drilling fluid system, and the underflow falls onto the vibrating screen. While the cyclone removes unwanted solids from the weighted drilling fluid, a large amount of barium is present in the underflow. The sieve under the cyclone's underflow separates large solid particles, while the barium passes through the screen and returns to the circulation tank.

The new, highly efficient desilter (integrated desilter) combines a high-G-force variable-path vibrating screen with an extended conical cyclone design to more effectively separate finer, drier materials, saving operating costs and reducing centrifuge pressure. Desilters are essential drilling fluid treatment equipment. Through efficient solids control technology, they effectively remove solids from drilling fluids, ensuring smooth drilling operations.

Drilling fluid desilter features:

1. Desilters of varying specifications and capacities can be manufactured and configured according to customer needs.

2. Operation and maintenance are simple, and drilling fluid desilter parts are interchangeable with those of internationally renowned brands.

3. Ball valves can be installed at the cyclone inlet and outlet, allowing for the customization of the number of cyclones in operation.

4. Industry-leading pickling, passivation, and hot-dip galvanizing processes are utilized, significantly extending the lifecycle of the drilling fluid desilter.

5. Utilizes international brand vibration motors, including Martin and OLI motors.

6. Electrical components are from internationally renowned brands such as Siemens and Schneider.

7. The desilting cyclone is constructed of highly wear-resistant, pure polyurethane or high-chromium cast iron. A German cyclone can also be installed.

Application areas:

Widely used in mud purification in oil/natural gas/coal gas drilling, solids control, trenchless construction, pipe jacking, sewage treatment, river dredging and other fields. The desilter's design and material selection give it high separation capacity and long life.

Drilling mud desilters are essential, critical equipment in oil and gas drilling processes, used to purify drilling fluid and improve drilling efficiency and safety.

Drilling desilters manufactured by TR Solids Control offer strong mud handling capabilities, high drilling fluid separation efficiency, and are easy to operate. Desilters also help reduce drilling failure rates, improve drilling efficiency, and ensure smooth drilling operations.
