High Temperature and High Density Reversible Emulsion Drilling Fluid

1.Technical Introduction

Reversible inverse emulsion drilling fluid technology refers to the reversible transformation of water in oil drilling fluid and oil in water drilling fluid under the action of external conditions, as as to have the advantages of oil-based drilling fluid and water-based drilling fluid.

In the drilling stage, the performance of reversible emulsified drilling fluid is equivalent to that of traditional oil-based drilling fluid, and has strong emulsification stability, rheological stability, pollution ability, pollution ability, inhibition and anti-pollution ability.

Reversible emulsified drilling fluid is helpful to solve the problems of poor completion and cementing quality, reservoir damage and oil-bearing drilling cuttings pollution of traditional oil-based drilling fluid. It is a new drilling fluid technology with great development prospect.     

2.Technical Characteristics

3.Technical Advantages

p The temperature is 100~150℃ and the density is 1.0~2.0g/cm³, all of them are adjustable.

p Two-way reversal of water in oil and oil in water

p The product has the advantages of greatly reducing the oil-water ratio, controlling the rheology, reducing filtration, stabilizing the wellbore and good rock carrying performance.

p The drilling fluid can be recycled, the filter cake can be easily removed and the drilling cuttings can be easily treated.

p It is cost-friendly in the whole process of drilling fluid utilization, later solid completion and environmental protection treatment of drilling cuttings
