The invention discloses a temporary plugging diverting method for achieving liquid-
solid-
liquid phase conversion by means of a natural geothermal field. The temporary plugging diverting method for achieving liquid-
solid-
liquid phase conversion by means of the natural geothermal field comprises the steps that (1) the
horizon of a reservoir needing temporary plugging is determined, and whether the reservoir needing temporary plugging is a crack or hole is determined; (2) the diversion plugging strength of the temporarily plugged reservoir is larger than or equal to the difference between the
maximum principle stress and the minimum
principal stress of the stratum is determined; (3) the plugging capacity of the
horizon of the temporarily plugged reservoir and the crack or the hole are testedthrough flowing experiments of a core and the crack or
pipe flow, and the use amount of a temporary plugging diversion
system is worked out; (4) according to the distribution curve of the temperatureof liquid in an oil
pipe in a shaft, the peak of bottom hole temperature is obtained; (5) an appropriate temporary plugging diversion
system is determined; (6) the use amount of displacing liquid is determined, wherein the use amount of the displacing liquid is larger than or equal to the sum of the volume of the shaft and the volume of a liquid infusion pipeline; (7) site operation is organized.According to the temporary plugging diverting method for achieving liquid-
solid-
liquid phase conversion by means of the natural geothermal field, liquid is infused into the plugged reservoir, the plugged rack and the plugged hole to achieve effective plugging, liquid-solid-
liquid change is achieved by means of the natural geothermal field, the requirements of the temporary plugging diversion technology are met, extra addition of gel breaker is not needed, and the application range is wide.
