Structure and Applications of KOSUN Desander for Oil and Gas Drilling

Sep 08, 2013

The desander is the two-level solids control equipment used for drilling fluids treatment. As one of the indispensable and important devices for stabilizing and regulating those technical indicators of the drilling fluids, the drilling mud desander has also been extensively used in the purification of the drilling fluids.

Desander is the second step in separation equipment for treating drilling liquid. It separates solids and liquid treated after shale shakers, recycles the barite of weighted drilling and removes the surplus cuttings that are bigger barite particles. As the combination of the hydrocyclone desander and the vibrating screen, the drilling mud desander is the three-level solids control equipment used in the solids control system of the drilling fluids. It is primarily made up of the vibrating screen, the distribution manifold as well as the hydrocyclones. The drilling mud desander is mainly used to remove the harmful solid phase with the granularity of more than 45μm so as to ensure the good properties of the drilling fluids.

The desander is primarily and widely applied in the petroleum industry, the oil and gas drilling, the exploration industry, the trench-less engineering, the geotechnical engineering, mining, metallurgy, coal as well as the hydroelectric industry.

Structure of KOSUN Desander

The desander system is made up of the screening system, the adjusting and supporting system, the aqueduct, the foundation, the pressure gauge as well as the desander hydrocyclones.
 

Desander


The desander is designed on the basis of particle setting principle. The separated medium-drilling liquid enters along the inner wall of clone spirally, depending on the pressure and speed produced by centrifugal pump. Under the function of centrifugal force and gravity, the larger particles are sunk along the inner wall of clone spirally and drained from bottom outlet to be separated in shale shaker with smaller mesh. Other mediums are ascending along clone spirally to enter the second separation device from overflow outlet for further purification.

Features & Benefits of KOSUN Desander

1. Polyurethane ( PU ) material or high-chromium cast iron for desander cones with longer using life.

2. Clamp type for easy maintenance.

3. Compact design with small footprint.

4. Flexible options for 1, 2 or 3 for different capacities.

5. Flexible fast connection is available for user assembly.

KOSUN is a professional solids control solution company which specializes in solids control system. KOSUN has been continually growing up and developing. In 2009, KOSUN Service Co., Ltd ( Kazakhstan ). and a solids control production base were founded in Aktobe of the Republic of Kazakhstan, which is also the only overseas solids control equipment and system production base for China. Relying on technical advantages of KOSUN and by dint of the local resources, KOSUN Service Co., Ltd ( KAZAKHSTAN ). can serve the oilfield drilling projects in the locality and its surrounding countries.
