STZ-2 of polymer salt-resistant filtrate reducer for drilling fluid

Polymer anti-salt fluid loss additive (STZ-2) for oil and gas field drilling fluid

1. Overview

STZ-2 is a low molecular weight polymer salt-resistant fluid loss agent made from propylene-based monomers through polymerization and chelation of metal ions. The product has the function of significantly reducing the filtration loss of drilling fluid and improving the quality of mud cake; it has strong resistance to temperature, salt and calcium, and the addition of STZ-2 is beneficial to adjust the performance of the system, and has good compatibility with other treatment agents. It has no adverse effect on other properties of drilling fluid; it is suitable for various types of water-based drilling fluid systems.

Technical indicators

3. technical characteristics

Whether in fresh water drilling fluid or in salt water drilling fluid, the water loss of drilling fluid can be significantly reduced and the quality of mud cake of drilling fluid can be improved. STZ-2 applies not only to polymer mud, but also to all water-based drilling fluid systems. The maximum temperature of STZ-2 used in drilling fluid can reach 150 ℃. If it is combined with other high temperature treatment agents, the temperature resistance of the STZ-2 can be improved. STZ-2 is different from the general fluid loss agent is the biggest feature of the viscosity of the drilling fluid effect is very low, does not damage the performance of the system.

4. instructions for use

The recommend addition amount of STZ-2 in polymer drilling fluid and other fresh water drilling fluid is 0.5~1.5%, and the recommend addition amount in brine mud is 1.5~2.5%, but the actual addition amount shall be determined according to different mud systems and different requirements of users for water loss reduction. The STZ-2 can be directly added to the dry agent, or prepared into an aqueous solution with a concentration of 10-20% to be added to the well slurry, or prepared into a mixed solution with other treatment agents to be added to the well slurry. STZ-2 to human eyes no irritation, no harm to the skin, non-toxic harmless environmentally friendly products, non-flammable and explosive goods.

5. packaging storage and transportation

Products packed in plastic bags, coat composite bag package. It can also be packaged according to the user contract. Store in a dry and ventilated place, pay attention to moisture. The shelf life is 18 months under the specified storage conditions.
