Abstract: During the development of oil and gas wells, although the foam stabilizing effect of the foam
stabilizing agent was known earlier, there is a little comparative study on its temperature resistance
performance. As the search for oil and gas resources gradually changed from shallow reservoirs to
high-temperature reservoirs, fracture type and low permeability reservoirs, the temperature resistance of
polymer foam stabilizers has become an important research topic. Three main fields of foam stabilizers are
reviewed in this paper: foam fracturing fluid stabilizer, foam oil displacement stabilizer, and foam
well-washing fluid stabilizer are compared and analyzed for their temperature resistance and their
advantages and disadvantages in oil field applications are described. In order to solve the problems of poor
temperature resistance, low foam stabilization effect and complex synthesis process of polymers at domestic
and foreign, improving synthetic technology, nanometer compounding, and self-assembly of functional
monomers are proposed to improve the temperature resistance and stability of polymers.
