Oil Drilling Grade CMC FEATURES

Oil Drilling Grade Carboxymethyl Cellulose (CMC) is an indispensable additive engineered to enhance the performance of drilling fluids. Our CMC exhibits exceptional viscosity and filtration control, making it crucial for maintaining the integrity of the borehole. Its high purity and thermal stability ensure that it withstands the demanding conditions of drilling operations.

The product’s superior fluid loss reduction capacity minimizes environmental impact by preventing unnecessary seepage. With its excellent rheological properties, our CMC ensures that drilling fluids achieve optimal flow, reducing the risk of wellbore instability. It also aids in the suspension of drill cuttings, enhancing the efficiency of the drilling process.

Our Oil Drilling Grade CMC is designed for rapid dispersion, ensuring quick and uniform mixing. It is compatible with a variety of brine systems, which offers versatility in different drilling scenarios. Choosing our CMC translates to smoother operations and cost-effectiveness, making it a smart choice for drilling professionals.

Viscosity and Mud Performance

Our Oil Drilling Grade CMC is tailored to provide exceptional viscosity, which is crucial for the drilling mud's performance. The right viscosity ensures the mud can carry drill cuttings to the surface efficiently, reducing the risk of clogging. Furthermore, it helps in maintaining the mud's thickness, even under high temperatures and shear conditions found deep within wells, ensuring consistent performance throughout the drilling process.

Thermal Stability and Salt Resistance

The thermal stability of our CMC stands out as it retains its properties under extreme temperatures that are commonly encountered in drilling operations. This stability is paired with excellent salt resistance, meaning it performs reliably in various saline environments, including freshwater, seawater, and saturated saltwater mud systems. Such resilience ensures the integrity of the drilling fluid over time, providing a consistent aid in complex drilling situations.

Fluid Loss Control

Controlling fluid loss is paramount in drilling operations, and our CMC excels in this aspect. It forms a thin, yet robust, low-permeability filter cake on the wellbore walls, which minimizes fluid loss into the surrounding formations. This feature is vital for preventing the reduction of hydrostatic pressure, which can lead to wellbore collapses or dangerous blowouts. Consequently, it enhances operational safety and reduces the environmental footprint of drilling activities by mitigating the contamination risks.

Rapid Dispersion and Compatibility

Designed for rapid dispersion, our Oil Drilling Grade CMC allows for quick and homogeneous mixing within the drilling fluid. This rapid integration is essential for operations that demand swift preparation of drilling mud. Our CMC is also compatible with a wide array of additives, reducing potential delays from incompatibility issues. This flexibility ensures that drilling operations can be tailored to specific geological conditions, optimizing performance and reducing operational downtime.

The Applications Of CMC In Oil Drilling Fluids

  • Non-Dispersed Systems:Strong carrying capacity for debris, inhibits the dispersion of clay, reduces the rate of clay slurry, stabilizes the wellbore, and effectively increases drilling speed.
  • Dispersed Systems:Good suspension capability, contains more solid phase, significantly increasing the stability of particles; most suitable for formulating high-density drilling fluids, adjusting the rheology of drilling fluids; forms a dense, high-quality mud cake in the drilling fluid. It also has a good effect in reducing fluid loss and free water.
  • Calcium-Treated Drilling Fluids:Good resistance to calcium, prevents excessive flocculation of clay particles caused by calcium ions, keeps the drilling fluid in a flocculated state, maintains stable solid content and rheology, and provides good resistance to calcium. Consequently, the performance is stable.
  • Saltwater Drilling Fluids, Seawater Drilling Fluids, Saturated Saltwater Drilling Fluids:Low sensitivity to salt, strong resistance to salt, calcium, and magnesium, can be used as a rheology modifier. Quickly adjusts the rheology of drilling fluids at low dosages. It also rapidly carries cuttings and maintains a low solid content, improving drilling speed. Used as a fluid loss reducer, it forms a dense mud cake, and since the filtrate from the cake filtration is very close to the original water of the formation, the damage to the oil and gas layer is minimal.
  • Potassium-Based Drilling Fluids:Low sensitivity to potassium, calcium, and magnesium salts; quickly and efficiently adjusts the rheology of drilling fluids. Besides having a good fluid loss reduction effect, it also has the ability to clear cuttings and drill bits, and it is notably effective for drill bits that are prone to clogging in the formation.
  • Low Solid Phase Drilling Fluids:Quickly and effectively adjusts the rheology of drilling fluids, excellent suspension capability, timely and effectively clears cuttings, maintains low solid content, increases drilling speed, stabilizes wellbore, and has a good fluid loss reduction effect.
  • Environmentally Friendly Drilling Fluids:The product is environmentally friendly, non-toxic, harmless, odorless, and biodegradable. It is not prone to decay during use. Due to the low maintenance cost of the drilling fluid, the health and safety of construction personnel are ensured. It meets the requirements of various complex geological conditions without harming agricultural production.

Applications of CMC in Completion Fluids

  • In Cementing Fluids:Enhances the flowability of cementing fluids, providing appropriate initial viscosity and lower fluid loss, while also protecting the wellbore by preventing liquid from entering pores and fractures.
  • As a Filling Fluid:Adjusts the fluidity, thixotropy, and suspension of solids in the fluid. Due to the product’s good salt resistance (especially to monovalent metal ions), it is particularly effective when used in clean saltwater packing fluids.
  • In Fracturing Fluids:Rapidly increases the viscosity of fracturing fluids to carry proppants into well fractures, building permeable channels, quickly reducing fluid loss, and thereby rapidly increasing formation pressure to achieve the effect of pressure transmission. It leaves no residue, does not harm the matrix, and can replace guar gum.
  • PAC-HVC for Clean Fracturing Fluids:Used in clean fracturing fluids, it requires a low dosage and reduces fluid loss. It has good salt resistance and temperature resistance. It is water-soluble with no residue, does not harm the base surface, has high pumpability, and provides significant friction, bringing power together with the proppant.

Special Function Products

  • Granulated Products:Improves working conditions by reducing dust, dissolves quickly, and enhances construction efficiency.
  • Instant Soluble Products:Can disperse and dissolve quickly in water, making it more convenient and simple to use in harsh drilling environments. It increases the efficiency of cement slurry preparation and requires less from construction equipment.
