Specialized Defoaming Solution for Oilwell Cementing -- Kelioil CX410L Liquid Defoamer
Targeted Foam Control for Cementing Operations to Enhance Well Construction Efficiency
I. Product Positioning: Foam Control Expert for Cement Slurry Systems
CX410L is a high-performance liquid defoamer specifically developed for oil and gas well cementing engineering. Aimed at the foam generation characteristics during cement slurry mixing and pumping, it achieves three major functions: rapid defoaming, long-acting foam inhibition, and efficient degassing, while ensuring no impact on slurry rheology, thickening time, and compressive strength. It is the preferred solution for high-temperature/high-pressure wells and complex cementing operations.
II. Core Technical Advantages -- Breaking Through Operational Bottlenecks in Four Dimensions
| Technical Index | Industry Pain Points | CX410L Solution |
|---|---|---|
| ① Ultra-Strong Defoaming Efficiency | Severe foam generation during mixing/pumping, affecting pump pressure stability | Achieves rapid defoaming within 10 seconds, with a foam inhibition rate >95% within 30 minutes |
| ② Broad-Spectrum Foam Inhibition | Persistent foam induced by additives (dispersants/retarders) | Compatible with mainstream cementing additive systems, mitigating secondary foaming risks |
| ③ High-Efficiency Dispersion | Uneven mixing of defoamer and slurry causing local performance fluctuations | Homogeneous dispersion in all systems (water-based/oil-based slurries) with no delamination risk |
| ④ Zero Interference | Traditional defoamers affecting slurry thickening time/strength development | With a dosage of 0.1-0.3% BWOC, rheological deviation <5% |
III. Engineering-Level Application Value -- Full-Process Adaptability from Lab to Wellsite
1. Extreme Condition Adaptability
Temperature Range: -10°C ~ 150°C (covering shallow, deep, and ultra-deep geothermal reservoirs)
Pressure Tolerance: Suitable for 20-140MPa high-pressure well annulus environments
System Compatibility:
▶ Dispersed cement slurries (e.g., Class G cement + DF-1 dispersant)
▶ Retarded cement slurries (e.g., HSR retarder systems)
▶ Low-density/high-density special cement slurries
2. Operational Efficiency Improvement
Mixing Stage: Foam volume reduced by >80%, circulation time shortened by 15-20%
Pumping Stage: Pump pressure fluctuation amplitude reduced to ±0.5MPa, minimizing equipment wear risks
Curing Stage: Degassing efficiency increased by 30%, reducing gas channeling hazards; compressive strength of cement stone improved by 5-8%
3. Environmental & Economic Benefits
Green Formula: Low VOC (<100g/L), compliant with API 13A environmental standards
High Cost-Effectiveness: Single-well cost 20-30% lower than traditional silicon-based defoamers, with only half the dosage of similar products
IV. Standardized Application Guidelines
1. Recommended Dosage: 0.1-0.3% BWOC (by cement mass), adjustable according to foam severity
2. Addition Methods:
▶ Dry Mixing: Premix with cement powder before adding water
▶ Wet Mixing: Add uniformly during late-stage slurry agitation, stirring for 3-5 minutes until homogeneous
3. Storage & Handling
Packaging: 25L/barrel (portable), 200L steel drum (conventional operations), IBC tote (large-scale construction)
Storage: Store in a cool, dry, shaded place with a 12-month shelf life; preheat to 15°C in low-temperature environments
V. Field Validation Case
A Shale Gas Horizontal Well Cementing Project
Challenge: Oil-based drilling fluid caused severe stable foam due to oil contamination during cement slurry mixing, with pump pressure fluctuating by 3MPa, risking lost circulation
Solution: After adding 0.2% CX410L, foam height dropped from 1.2m to 0.2m, pump pressure stabilized within ±0.8MPa of the design value, and cementing quality excellence rate reached 92% (18% higher than adjacent wells)
VI. Value Proposition for Petroleum Professionals
With CX410L, every cubic meter of cement slurry becomes a reliable isolation barrier
✔ Eliminate foam interference and unlock a cementing experience with low pump pressure, high displacement rate, and zero gas channeling
✔ From conventional wells to shale gas/deep oil-gas wells, one defoamer for all scenarios
✔ Technical team provides full-cycle support from lab formula optimization to on-site operation guidance
