Product Description

Sodium Carboxy

methyl Cellulose (Low Viscosity) - LV - CMC

Sodium Carboxymethyl Cellulose (Low Viscosity), abbreviated as LV - CMC, is a high - quality additive produced by Beijing Sanherunjing Technology Co., Ltd. for drilling fluid applications. Derived from natural cellulose through chemical modification, LV - CMC is presented as a powder - like substance and comes in a 25 - kilogram package. It has become a widely used material in the drilling industry due to its excellent performance in controlling drilling fluid properties.

Functions and Characteristics

Product Features and Advantages

Broad - Spectrum Adaptability: LV - CMC is suitable for both freshwater and saltwater drilling fluid systems. It can maintain its performance stability under different salinity conditions, providing flexibility in various drilling environments.

Effective Filtrate Loss Control: It has strong ability to reduce the filtrate loss of drilling fluids. By forming a thin and dense filter cake on the wellbore wall, it effectively prevents the invasion of formation fluids into the wellbore, protecting the formation and ensuring wellbore stability.

Low Viscosity with Good Suspension: Despite being a low - viscosity product, LV - CMC still provides sufficient suspension ability for drill cuttings in the drilling fluid. This helps to keep the cuttings in suspension during circulation and prevents them from settling at the bottom of the wellbore.

Good Compatibility: LV - CMC can be well - blended with other drilling fluid additives, such as bentonite, polymers, and weighting agents, without causing adverse reactions. This allows for the formulation of optimized drilling fluid systems according to specific drilling requirements.

Environmental Friendliness: As a product derived from natural cellulose, LV - CMC is biodegradable and has a relatively low environmental impact compared to some synthetic additives, meeting the environmental protection requirements of modern drilling operations.

Specification

‌Item	‌Specification
Freshwater Drilling Fluid	0.3%-0.5%
Saltwater Drilling Fluid	0.5%-1.0%
Application Scenarios	Freshwater Drilling Fluid Systems
Application Scenarios	Saltwater Drilling Fluid Systems
Main Functions	Filtrate Loss Reduction: The primary function of LV - CMC is to significantly reduce the filtrate loss of drilling fluids. In freshwater drilling fluids, it can effectively control the water penetration into the formation, while in saltwater drilling fluids, it maintains its filtrate - reducing performance even in high - salinity environments.
Main Functions	Slight Viscosity Adjustment: Although it is a low - viscosity product, LV - CMC can slightly increase the viscosity of the drilling fluid, improving the fluid's ability to carry cuttings and enhance the suspension effect. This is beneficial for maintaining a stable drilling process.
Main Functions	Enhanced Wellbore Wall Protection: By forming a stable filter cake on the wellbore wall, LV - CMC protects the wellbore from collapse and erosion, especially in formations with poor consolidation or high permeability.
