Pregelatinized starch is a kind of natural starch made from corn starch or tapioca starch, which is easy to process and widely used as a modified starch. As long as it is gelatinized with cold water, the trouble of heating gelatinization is avoided. Widely used in medicine, food, cosmetics, feed, oil drilling, metal casting, textile, paper and other industries.

The barrel and screw structure used in the modified corn starch processing machine produced by HIMAX adopts water cooling and oil cooling systems, and the screw adopts alloy material surface nitriding treatment to increase the speed; the production temperature is adjustable and controllable, and the screw speed is all controlled by the frequency converter; After the parameters are set, automatic production can be realized, which greatly saves production. We also launch various types of extruders according to the production requirements of customers.

The modified starch produced by the Himax modified starch production line has stable product quality and rich resources. It has good water loss and salt tolerance, and is more suitable for oil drilling. Stable performance, pregelatinized starch is a kind of drilling starch, also known as fluid loss control agent in the drilling industry.

Application of Pregelatinized Starch in Petroleum Drilling

1. The role of protective glue

In order to form a mud cake with low permeability, the particle size of the clay particles in the drilling fluid must have an appropriate particle size distribution, and a lot of fine particles are required.

2. Increasing the filtrate viscosity can reduce the fluid loss

The fluid loss is inversely proportional to the 0.5 power of the viscosity of the drilling fluid filtrate. After adding an organic filter reducer to the drilling fluid, the viscosity of the filtrate increases and the filtration capacity decreases.

3. Improve the degree of hydration of mobile soil particles in drilling fluid

This reduces the fluid loss, and the filtrate superplasticizer is adsorbed on the soil particles moving in the drilling fluid, increasing the degree of hydration of the particles, making the hydration film thicker, and the formed filter cake is easily deformed under high pressure, and the penetration of the filter cake reduced sex.

4. The pore blocking effect of the fluid loss reducer molecule itself

The molecular size of the organic polymer fluid loss control agent is within the range of colloidal particles, after adding these external treatment agents. On the one hand, the long chain of the molecule is wedged into the gap of the filter cake, on the other hand, the long chain is curled into a ball to block the micropores of the filter cake, making the filter cake thin and fine, thereby reducing the fluid loss.
