AI Technical Summary

Technical Problem

The application of existing VES fracturing fluids in high-salinity reservoirs and offshore oil fields is limited due to their high cost, low temperature resistance, complex synthesis process, complex fracturing fluid system composition, and significant formation damage.

Method used

Using a high molecular weight surfactant as the main agent and adding a co-surfactant to form a physical cross-linked network structure, combined with a simple gel breaking method, a high elasticity adhesive for oilfield fracturing is prepared, which has good temperature resistance, salt resistance and shear resistance.

Benefits of technology

It achieves low-cost, low-residue fracturing effects in high-temperature deep oil reservoir stimulation, possesses good viscoelasticity and sand-suspending properties, and is suitable for high-salinity oil reservoirs and offshore oil fields.
