摘　　要：新型相变压裂技术主要利用液固支撑剂材料对温度的响应,在注入时以流体形式进入地层,在相应条件下通过液固相态转变形成既能支持裂缝又具有导流能力的独立的固体支撑剂。该液固相变支撑剂相变性能的评价结果表明随着温度的升高,开始相变时间、完全相变时间和形成耐压相变固体时间越短;且不同矿化度对液固相变支撑剂的相变没有影响;动态和静态对液固相变支撑剂形成的固体有一定影响。The new phase change fracturing technology utilizes the temperature response of the liquid-solid proppant material to perform liquid-solid phase transition under appropriate conditions,entering the formation as a fluid during injection,and forming an independent solid proppant capable of supporting fractures and conducting flows through the liquid-solid phase transition.The evaluation results of the phase change properties of the liquid-solid phase change proppant show that the time of incipient phase change,complete phase change and formation of pressure-resistant phase change solid become shorter as the temperature increases.Different mineralization degree has no effect on the proppant phase transition.The dynamic and static state of the proppant have a certain influence on the solid formation of the liquid-solid phase change proppant.
