The application of CMC in oil drilling mainly covers drilling fluid thickening, fluid loss control, viscosity adjustment and leakage control. These applications can help improve drilling fluid performance, increase drilling efficiency, and protect formation integrity.
CMC (Hydroxyethyl Cellulose) has a variety of applications in oil drilling.
1️⃣ Drilling fluid thickener: CMC can be used as a thickening agent for drilling fluid to increase the viscosity and suspension of drilling fluid. By controlling the viscosity of the drilling fluid, the suspension ability and cutting ability of the drilling fluid can be improved, and the settlement of solid particles and solid accumulation near the bottom of the well can be reduced.
2️⃣ Loss of filtration preparation: CMC can be used as a preparation for filtration loss control to adjust the fluid loss rate between the drilling fluid and the well wall. It can form a thin film on the well wall, fill and seal the pores of the well wall, reduce the fluid loss rate of drilling fluid, thereby reducing the liquid exchange with the formation, preventing formation rupture and well wall collapse.
3️⃣ Viscosity control agent: CMC can be used to control the viscosity of drilling fluid so that it has appropriate fluidity and pumpability. By adjusting the concentration and molecular weight of CMC, it can adapt to different drilling conditions and well depths, and maintain the fluidity of the drilling fluid in the wellbore.
4️⃣ Loss control preparation: CMC can also be used to control drilling fluid loss, that is, to prevent drilling fluid from losing into the formation through cracks or pores. It can be used in combination with other additives to form a sealing film to fill and seal the formation's leakage channels and reduce the risk of leakage.
