Product Introduction:

When turbulent flow is difficult to achieve, using effective laminar isolation fluid technology is an effective means to improve displacement efficiency in well cementing engineering design. Effective laminar flow isolation liquid technology can easily meet laminar flow rheological and density requirements through formula adjustment, and form rheological and density gradients for cement slurry, mud, and isolation liquid.

Advantages:

Simple on-site mixing

Can form good rheological and density gradients with mud and cementing slurry

Suitable for various situations

Typical performance and application conditions:

The ELViS system was successfully commercialized in 2009 and has been applied in many oil and gas fields worldwide. Practice has proven that this technology is effective under the following conditions:

Bottom static temperature: 95-320 ° F (35-160 ° C)

Density: 10.0 ppg to 20.5 ppg (1.20-2.45 g/cm3)

Preparation of water: freshwater, seawater, saltwater

Rheology: adjustable below 160 ° C

API mud water loss: ≤ 50 mL

The typical ELViS system performance is as follows:
