The use of polymer drilling fluid helps to drill through reactive formations. The fluids help in especially, the shale inhibition i.e., insertion, and reduce the space between the clay platelets so that water molecules will not penetrate and cause swelling.
The polymers are added to the drilling muds to design drilling fluids for specific drilling conditions. Polymers help in allowing the complete replacement of clay when drilling through formations with water-sensitive shales in water-producing zones. Polymers work as lubricants, foaming agents, control agents, etc.
Potassium chloride is a shale inhibitor that is used comprehensively as the base for polymer drilling fluid. This base of Potassium Chloride is less expensive and highly effective. Properly designed and maintained fluids perform various functions that are essential for constructing purposes. Let us know about the functions of Polymer Fluids.
- Performing better transport drilled cuttings during construction
- Helps in controlling the hydrostatic pressure to prevent the incursion of gas that leads to safety and stability.
- Polymer drilling fluid helps in minimizing formation damage.
- The fluid helps in lubricating and cooling the drill string.
- Provides information about the wellbore, a wellbore is the hole that is drilled to aid in the investigation and recovery of natural resources.
Polymer Drilling fluid helps in construction purposes. The use of polymer drilling fluid is made for deep excavations and deep excavations are done with the help of various construction equipment like power shovels, bulldozers, scrapers, etc. There are many companies that provide this construction equipment for hire. Workers hire the equipment when there is some temporary work or limited work that does not require huge spending.
The Conclusion
So, the polymer drilling fluids act as lubricants, viscosifiers, filtration control agents, and foaming agents as well. If used properly, it helps in performing well during construction such as, minimizing formation risks, transporting cutting to the surface, and so on, hence making the process successful.
