Details description
Product Overview
Kangjing New Materials’ ultra-fine oil-well cement is an ultrafine inorganic mineral cementing material prepared using advanced particle-size control technology, involving physical crushing, fine grinding, particle shaping, and multi-stage classification and sorting processes, with particle size controlled at 1–10 μm The scope encompasses the incorporation of nanoscale active components to achieve synergistic optimization of the material’s microstructure and properties.
Through systematic design of particle gradation and the active system, the product not only ensures slurry stability but also exhibits excellent flowability, pumpability, and anti-settling performance. Moreover, it allows for precise adjustment of slurry density, thickening time, and job performance in response to varying downhole temperature, pressure, and formation conditions, thereby meeting the demanding requirements of complex operational scenarios.
This product combines deep penetration, high-strength cementing performance, and outstanding impermeability and durability, enabling it to effectively penetrate microfractures and low-permeability reservoirs to achieve efficient isolation of oil, gas, and water zones as well as long-term stable support. It maintains structural stability even under high-temperature and high-pressure conditions, and upon setting forms a dense, monolithic cement structure that significantly enhances wellbore stability and cementing quality.
The product is widely used in cementing, leak sealing, and remediation operations for oil wells, gas wells, and shale oil and gas wells, particularly for sealing and reinforcement needs in microfractured formations, low-permeability reservoirs, and complex well conditions.
Core Advantages
(1) Deep Penetration, Efficient Plugging, and Enhanced Success Rate
It boasts exceptional penetration capability, enabling it to penetrate deeply into complex geological formations such as fine sand, silt, and silty clay, as well as effectively enter microfractures and low-permeability rock layers, thereby achieving deep-seal cementing that is difficult to attain with conventional cementing materials.
Significantly improve the success rate of plugging operations and reduce the risks associated with repeated treatments and construction.
(2) High pack-off capability, prevention of channeling, and enhanced cementing quality
Upon curing, it forms a dense structure with a plugging efficiency of up to 99.9%, effectively isolating oil, gas, and water layers and preventing interlayer channeling.
Enhance cementing integrity to ensure stable hydrocarbon flow paths and production safety, thereby increasing oil and gas recovery by approximately 3%–5%.
(3) High-temperature and high-pressure stability—adapted to complex well conditions
Maintains stable performance under deep-well and complex temperature–pressure conditions (high temperature >200°C, high pressure >20 MPa) without failure or decomposition.
Suitable for deep wells, ultra-deep wells, and complex reservoir environments.
(4) High-strength grouting, impermeability and durability, and stable wellbore structure
The consolidated body exhibits high strength and a dense structure, with outstanding impermeability and long-term stability. Moreover, it maintains excellent fluid-loss control under high-temperature and high-pressure conditions, effectively reducing fluid loss and optimizing filter cake structure.
· Enhance wellbore stability
· Reducing the risk of downhole losses and collapses
· Improve overall cementing success rate
(5) Controllable construction performance—suitable for a wide range of working conditions
It exhibits excellent fluidity, pumpability, and anti-settling properties, enabling stable squeeze-injection operations across a wide range of pressure conditions—both below and above the formation fracture pressure. Its setting time is adjustable, and it develops adequate strength.
· Adaptable to varying well depths and formation conditions
· Improve construction efficiency and reduce non-productive time.
· Reduce construction difficulty and uncertainty
