The content of solids in the drilling fluid can obviously decrease the drilling speed of the drilling equipment, even may cause the drilling accident and lead to drilling cost increasing greatly. The equipment used in the drilling fluid circulation is mainly used to control the content of the solids in the drilling fluid. Experiments proved that the content of solids is reduced by 1%, and the construction drilling speed will be improved at least 10%, and the smaller solids size, the greater impact on the mechanical drilling speed.
Solids control equipment function
1. Remove harmful solids to ensure continuous drilling.
2. Ensure drilling safety to prevent accidents.
3. Saving energy
4. Reduce pollution and protect environment
Presently at domestic, drilling mud shale shaker types is less, crawler type non vibrating screen equipment, environmental protection special solid control equipment for offshore drilling and multi- function mud circulation system suitable for multi - work situations, etc. They enrich solids control equipment constantly.
For recent years, theoretical research and manufacturing level about drilling fluid solid control equipment have been developed in China constantly. Especially in theoretical research, such as work principle of shale shaker, principle structure of desander and desilter cyclone has reached or approached the world advanced level.
