Concrete application:The present embodiment is mainly used in cyclic steam stimulation, and cyclic steam stimulation is in current thickened oil recovery
Main Means, but after pressure break during crack closure temperature than relatively low, it is necessary to the low temperature curing properties of sand control proppant,
After proppant solidification, cyclic steam stimulation is carried out, this process temperature is higher, needs that there is suitable heat resistance after consolidation,
High temperature system in functional layer of the present invention is played a role, can not only heatproof, and can under the high temperature conditions increase consolidation strength.
During concrete application, enhancement layer:Increase the compression strength of proppant itself, reach under certain clossing pressure
Use, keep proppant flow conductivity, reach volume increase purpose;Functional layer:Various condition solidifications are realized, is increased between proppant
Bonding, realizes consolidation, and can reach suitable consolidation strength, so as to reach the purpose of sand control;Dispersion layer:In manufacturing process
Because temperature is higher after middle functional layer addition, mutually it is adhered between proppant particles, it is to avoid be adhered addition dispersion layer and disperseed,
Surfactant is added to realize simultaneously hydrophilic, so as to increase the compatibility with fracturing fluid, while reinforcing agent can be increased
Compatibility, so as to increase consolidation strength.
