Drilling Fluid Additive Anionic Polyacrylamide
On the Function of Drilling Fluid Additive Anionic Polyacrylamide
The drilling industry is related to the production of oil and gas, and the matter involves difficulties. It cannot be done well without intensive research. In the meantime, the effectiveness of drilling fluid additives is the key, and anionic polyacrylamide plays a crucial role in the drilling fluid system.
Anionic polyacrylamide has excellent thickening properties. When drilling, it is necessary to keep the drilling fluid with an appropriate viscosity to facilitate the carrying of cuttings and stabilize the well wall. After the anionic polyacrylamide is integrated into the drilling fluid, its molecular chain extends in the solution, and the viscosity of the drilling fluid is significantly improved by the interaction with water molecules and the entanglement between molecules. It makes the cuttings return to the surface smoothly with the circulation of the drilling fluid, so as not to settle at the bottom of the well, and ensures the smooth progress of the drilling operation.
It also has good fluid loss reduction. During the drilling process, the drilling fluid is in contact with the formation. If the fluid loss is too large, it is easy to cause many problems, such as formation collapse, drilling stuck, etc. Anionic polyacrylamide can form a dense filter cake on the surface of the well wall, effectively reducing the fluid loss. This filter cake has a tight texture, which can prevent excessive water in the drilling fluid from penetrating into the formation, maintain the stability of the formation, and ensure the safety of drilling operations.
Furthermore, anionic polyacrylamide is also effective in flocculation. Drilling fluids often contain various types of solid particles, and too many solid particles will affect the performance of drilling fluids. Anionic polyacrylamide can make these solid particles flocculate into larger aggregates, which can be easily removed by solid control equipment, thereby optimizing the performance of drilling fluids and improving drilling efficiency.
In summary, anionic polyacrylamide is used in drilling fluid systems to thicken, reduce filtration loss, flocculate and other functions, providing a solid guarantee for the efficient and safe development of drilling operations. It is an indispensable key ingredient in drilling fluid additives.
