Perlite floating beads

Perlite floating beads, with fine particles, light color, high compressive strength and good fluidity.

The low-density cement slurry prepared by using the lightening agent has good strength, can reduce the resolving power of annular liquid column, can meet the cementing requirements of low-pressure and easy-leakage layers, and realize the cementing in long sealing section. Water-soluble polymer in mud system can absorb hydration layer, bind more free water, block the gap between cement particles and reduce the permeability of cement filter cake. The mud system has a certain viscosity, and the slurry is not easy to dehydrate, which can further reduce the water loss, block the local leakage layer in the cementing process, and effectively reduce the cost.

Perlite for oil field cementing has a particle size range of 10 ~ 250 μ M, and has excellent properties such as light weight, no toxicity, no smell, corrosion resistance, high temperature resistance, compression resistance, insulation, sound insulation and small thermal conductivity. The density is generally 240- perlite floating beads

Perlite floating beads, with fine particles, light color, high compressive strength and good fluidity, are the best substitute for the transformation of domestic oilfield cementing materials from luxury materials-power plant fly ash floating beads to practical materials, and the material cost is only a fraction of that of power plant fly ash floating beads. At present, they are widely used in oilfield oil cementing field and adopted by customers in oil industry at home and abroad, which significantly reduces the cementing cost.

Perlite for oilfield cementing has a particle size range of 10 ~ 250 μ M, and has excellent properties such as light weight, innocuity, tasteless, corrosion resistance, high temperature resistance, compression resistance, insulation, sound insulation and small thermal conductivity, and its density is generally 240-350kg/m3. Used as cement lightening agent, it is mixed with cement to form perlite cement low density slurry system with the following characteristics:

1. It has good performance of reducing weight and water loss, stable slurry system, good fluidity and high compressive strength, which can significantly reduce cementing cost, prolong the service life of oil wells and improve service performance

2. Low density and wide slurry density range, which is suitable for cementing wells with low formation pressure and easy leakage;

3. On-site construction mixing is simple and easy to operate, without flash setting and pump suppression, and has a good application prospect in areas with low pressure, easy leakage and long sealing period. Physical characteristics:

Particle size range: 0.24-0.10mm...Particle size distribution: 0.24-0.18mm: 28%, 0.18-0.15mm: 40%,
