Why we need solids control equipment?
Nowadays, solids control equipment become necessary in many industries, especially in oil & gas drilling industry. But many people do not understand completely the basic principles of drilling fluids solids control. Drilling solids increasing can seriously affect the drilling rig and drilling mud property. So drilling solids need to be removed at the surface by solids control equipment, such as shale shaker, mud cleaner, centrifuge, etc. used to reduce the risk.
The solids effect on drilling fluid
Drilling solids can damage drilling mud property and increase drilling cost, and also create large drilling processing disposal cost. To drill an oil or gas well fast, safely under budget, it is necessary to remove the drilling solids. If these drilling solids can not be removed timely, they would cause many problems, including:
- Filtrate damage to formation
- Drilling rate limits
- Drilling string stuck
- Borehole Problem
- Lost circulation problem
- Direct drilling fluid cost
- Increasing disposal cost
Using solids control equipment necessity
Nobody wish these above problems happen in any drilling project, but they do exist indeed. The effects of drilling solids on economics of drilling a well is subtle, and increasing of drilling solids does not result in a disaster immediately on a drilling rig. But after a long term, because of drilling solids abounding, maybe there will happen some accidents, such as well blowout. So solids control equipment used to remove solids can prevent above accidents from occurring.
Aipu solids control system
That is why the drilling fluids are used to bring drilling solids to the surface, and removed timely by the solids control equipment, such as shale shaker, desander, desilter, mud cleaner, centrifuge, etc. But not all the solids are removed. Some solids that smaller than the shaker screen openings would stay in drilling fluids, and other additive agents, such as barite, clay, etc. They are also essential to adjust drilling fluids property.
In a word, the main function of solids control is used to clean and process drilling mud so that avoid unnecessary trouble.
