Cationic asphalt powder for drilling fluid

Main ingredients

Cationic asphalt powder for drilling fluid is a high-quality powdered asphalt treatment agent produced through special processes using natural asphalt and cationic surfactants. Its asphalt content is much higher than that of sulfonated asphalt, so it has excellent sealing effect.

Nature and Use

The product is a black powder, and the insoluble asphalt dispersed in drilling fluid can adsorb on the surface of shale, forming a thin, tough, and low-permeability hydrophobic oil film. It can also seal formation pores and microcracks under pressure difference, reducing the amount of filtrate invading the formation. Cationic groups have a good inhibitory effect, so this product can effectively inhibit the hydration and expansion of shale, prevent shale peeling and collapse, and stabilize the wellbore.

Main technical indicators

Product features

1. Has good water dispersibility, no agglomeration or floating phenomenon;
2. Has good shale inhibitory properties, can effectively inhibit shale hydration and expansion, prevent shale peeling and collapse, and stabilize the wellbore;
3. It has a good sealing effect and can be combined with other plugging agents to improve its sealing effect:
4. Has a good protective effect on oil and gas reservoirs;
5. Not increasing viscosity, especially suitable for preparing high-density drilling and completion fluids;
6. It has good compatibility with other treatment agents and can be directly added to various drilling and completion fluids with a dosage of 1% -3%.

Usage

Just mix it directly into the drilling fluid.

Recommended dosage: 1.0% -2.0%.
