NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer its premium Modified Starch Powder, a specialized chemical auxiliary agent formulated for the demanding environment of oilfield drilling operations. Recognized for its efficacy and reliability, this product is an indispensable additive in optimizing the performance of water-based drilling fluids.

Our Modified Starch Powder serves primarily as a superior fluid loss control additive. It is highly effective across a wide spectrum of water-based drilling fluid compositions, performing robustly in systems ranging from fresh water to heavily salt-saturated brines. By effectively sealing porous formations and filter cake permeability, it minimizes filtrate invasion into the reservoir, thereby preserving formation integrity and maintaining wellbore stability.

In addition to its exceptional filtration control capabilities, this versatile powder also contributes valuable shale inhibitive properties. It helps to encapsulate reactive shale particles, reducing their hydration and dispersion. This inhibitory action is crucial in preventing wellbore collapse, mitigating sticky hole conditions, and lowering torque and drag during drilling, leading to smoother and more efficient operations.

The product is supplied as a fine White Powder. Its technical specifications are tailored for optimal performance in drilling fluids. Suspension capability is measured at ≤18 in 40g/L saline water (600r/min reading) and ≤20 in saturated salt-water (600r/min reading). Filtration loss is maintained at ≤10 mL in both 40g/L saline water and saturated salt-water. Crucially, the product features Nil residue above 2000μm, ensuring it does not contribute to formation damage or blockages.

Application of the Modified Starch Powder is flexible. It can be added directly to the active drilling fluid system, or for optimal dispersion, it can be slowly introduced into water to pre-form a dense colloid solution before incorporation. This method helps prevent the formation of lumps and ensures a uniform blend, maximizing its effectiveness. The recommended dosage typically ranges from 1.0% to 2.0%, but adjustments may be necessary based on specific drilling fluid properties, formation characteristics, and desired performance levels.

Packaging for our Modified Starch Powder is designed for durability and convenience. The standard packaging consists of multi-wall bags with an inner polythene lining, each containing 25 kg net weight of product. We also understand that different logistical requirements exist, and NINGBO INNO PHARMCHEM CO.,LTD. is equipped to provide special packaging solutions upon customer request. For shipping, a 20'FCL container can typically accommodate approximately 12.5 TON with pallets or 16 TON without pallets.

Maintaining the quality of Modified Starch Powder requires adherence to specific storage conditions. The product should be stored in a shady, dry, and well-ventilated warehouse. The recommended environment temperature should be kept below 122ºF (50ºC), and relative humidity should not exceed 50%. It is essential to protect the bags from direct sunlight and rain and to store them away from any sources of heat or fire. For stacking, it is recommended not to pile more than 8 layers high to ensure stability and prevent damage. Under these conditions, the product maintains a reliable shelf life of 2 years.
