Industrial Starch-Based Drilling Mud Additives and Fluid Loss Control Polymers

 

Jiahe's Drilling Mud Materials are primarily modified starch additives developed for oil and gas drilling fluids. Produced from natural starch through controlled modification, these materials are designed to reduce drilling fluid filtration loss, improve viscosity and suspension, and help maintain mud-system stability. Different grades are available for normal-temperature, high-temperature and salt-containing drilling conditions, including fluid-loss-control starch and thickening agents. For more demanding drilling environments, formulations can be adjusted for temperature and salt resistance to better match the drilling fluid system and formation conditions.

Working Principle and Functional Features

Rapid Hydration

The modified starch particles swell quickly in water and form a tight network that blocks pore spaces in the rock formation.

Thin Filter Cake

Adsorbs onto drill solids to build a thin, strong filter cake, which stops fluid from leaking into oil and gas zones.

Salt Resistance

Chemical treatment protects the polymer chains from breaking down in high salt and calcium ion environments.

Shear-Thinning Flow

Thins out under high pump pressure to reduce friction, but thick enough when static to hold drill cuttings in place.

 

Applications

Oil and Gas Drilling: Used as a primary fluid loss additive in fresh water, seawater, and salt mud systems.

 

Geothermal Drilling: Applied in water-based muds that face moderate downhole heat.

 

Borehole Stabilization: Helps prevent water-sensitive shale formations from swelling and collapsing.

 

Workover and Completion Fluids: Protects the well formation from damage during final well operations.

FAQ

 

Q: How does this modified starch perform in salt water compared to raw starch?

A: Raw starch breaks down quickly in salty water and rots from bacteria. Our chemically modified starch resists salt and chemical breakdown, keeping fluid loss low in heavy brine muds.

Q: Does this starch make the mud too thick?

A: Raw starches often make mud viscosity too high. Our special modification method controls molecular weight so you get low fluid loss without high pressure spikes in the mud system.

Q: What is the correct mixing method at the rig site?

A: Slowly add the powder through a high-shear chemical mixing hopper into the mud system. Do not dump dry bags directly into quiet fluid pools to avoid surface lumps.

Q: How long can the dry product be stored?

A: When stored in a cool, dry, and well-ventilated warehouse away from moisture, the product stays stable for 24 months.

Q: Can you adjust the product for higher well temperatures?

A: Yes. We can adjust the chemical modification level to match downhole temperature needs up to 150 degrees C.

Q: What testing standards do you follow?

A: All production and testing steps strictly follow API Specification 13A (ISO 13500) standards for oil and gas drilling materials.
