1. Amphiphilic non-crosslinking multi-functional emulsion thickener adopts the integrated design of drag reduction, anti-swelling and drainage aid, and is amphiphilic, instant and thickening;<br />
2. When the ratio is low (0.1-0.2%), it can be used as a drag reducer (slick water) to achieve drag reduction and joint creation;<br />
3. When the ratio is high (0.4-1.2%), it can thicken and carry sand to meet the fracturing requirements of high sand-carrying ratio, and one agent can be used for multiple purposes.
Shandong Avant New Material Technology Co., Ltd. signed a cooperation framework agreement with Sinopec Catalyst Co., Ltd., relying on the existing resource advantages of both parties, giving full play to the advantages of technology, talents, achievements and markets, aiming at new materials, new catalysts, green low-carbon technologies and bio-energy and other fields to further promote in-depth cooperation between industry, universities and research institutes.
Based on this background, the amphiphilic non-crosslinking multifunctional emulsion thickener was jointly developed by Sinopec Catalyst Shandong Co., Ltd., a wholly-owned subsidiary of Sinopec Catalyst Co., Ltd., and Shandong Avant New Material Technology.
Amphiphilic non-crosslinking multi-functional emulsion thickener adopts the integrated design of drag reduction, anti-swelling and drainage aid, and is amphiphilic, instant and thickening. When the ratio is low (0.1~0.2%), it can be used as a drag reducer (slick water) to achieve drag reduction and joint creation; when the ratio is high (0.4~1.2%), it can thicken the sand and carry it to achieve a high sand-carrying ratio. One dose is multi-purpose.
Amphiphilic non-crosslinking multifunctional emulsion thickener dissolves in 1 minute, which can realize continuous mixing on-line and large-volume construction. The residue rate after gel breaking is low, and it can be efficiently flowback. The fracturing operation process is simple. The compounded cross-linking agent can expand the universality of the product to deal with high-temperature and high-salt reservoir operations. This technical product has carried out thousands of fracturing operations and has been recognized by the application unit.
The amphiphilic crosslink-free multifunctional emulsion thickener adopts the emulsion polymerization method, breaking through the multifunctional homogeneous emulsification + controllable micro-block linear copolymerization technology.
Focus on factors that affect product solubility performance:
Keep the molecular structure linear, and the filter factor is close to 1;
Regular molecular structure, narrow range of molecular weight distribution;
A special emulsifier is added during the polymerization emulsification process to achieve the purpose of solubilization and dispersion, so as to develop a series of thickener emulsion polymers for fracturing.
