During the period of 1920s~1960s, water-based drilling fluid was used. At that time, water-based drilling fluid was rather simple and the main type in this stage was dispersed water-based drilling fluid. (1) From 1921 to 1922, barite and iron oxide powder were used as weighting materials. (2) In 192

Now, all major oil countries consider the development of drilling waste treatment technologies quite significant, and have had a head start in relevant treatment devices and equipment. Countries like U.S., Canada, France, etc. adopt four-stage solids control equipment in collecting drill cuttings an
Temperature is an important control parameter for sewage plants, especially in the North. In response to changes in temperature, sewage plants should take the initiative to manage operations rather than passively make adjustments. Only by understanding the laws of nature and the microbial habits, ca

KOSUN double-deck linear shale shaker can achieve four treatment effects: 1. Can be used as a two-stage shale shaker; 2. The lower screen can be used as a shale shaker and the upper screen as an underflow shaker of desander; 3. The lower screen can be used as a shale shaker and the upper screen as a
Screw Pump is an ideal pump used to feed drilling fluids to decanter centrifuge since drilling fluids is pushed to proceed along axial direction evenly. Therefore, the inner flow speed is kept low, volume unchanged and pressure stable so that vortex and agitation are prevented. Screw Pump is useful
