Overview
This product is only in recent years by the development of organic fluorine, silicone surfactants are commonly used surfactant complex and the development of a new product, due to special synergies and fluorine, silicon surface several surfactants the characteristics of the active agent itself, making this cleanup agent only low surface tension and the temperature is very effective. As the cleanup agent used in all kinds of non-ionic substances and fracturing system so it can better other additives compatibility. The most outstanding feature of the product is that it adds a special silicone-based surfactants, because of the common ion effect can kind of cleanup agent with minimal core surface adsorption, which also ensures that the activity of the product, to improve flowback efficiency of the fracturing fluid, flowback efficiency greater than 80% under the same conditions.

Usage
Used as a water-based fracturing fluid and acidizing fluid additives to improve the working fluid back to displacement, reducing formation damage.
Technical Note
1. Mechanism of action:
Fracturing and acidizing are the main measures to increase production of oil and gas wells, the working fluid flowback effect is one of the key factors affecting the success of the construction, especially for the formation of low energy, poor permeability strata, the working fluid is difficult to completely discharge rapidly strata, it cause clay swelling, emulsion blockage, capillary water lock and calcium, iron, silicon and other secondary sedimentation pore throat blockage formation damage. Therefore, the use of chemical cleanup technology can effectively discharge formation fluids.
2. Using the methods and processes applicable conditions:
This product is added directly by a certain percentage and acid fracturing fluid was mixed evenly. Generally recommended dosage is 0.2-1.0%.
Product packaging
Dressed with iron or plastic barrel, net weight per barrel (200 ± 1) kg. Also according to customer requirements.
Product storage
Product shelf life of 1 year. |
