Abstract

A phase change fracturing method. The phase change fracturing method comprises: injecting a phase change material liquid into a stratum, wherein the phase change material liquid undergoes phase change under the stratum condition to form a honeycomb solid-phase proppant, thereby completing phase change fracturing. According to the fracturing method, the phase change material liquid is injected into the stratum, and the phase change material liquid undergoes phase change to form the honeycomb solid-phase proppant, such that fracturing is implemented without additionally adding any proppant. Moreover, the formed honeycomb solid-phase proppant has high compressive strength, low deformation, and excellent flow conductivity.
