Disclosed is a method for determining three-dimensional in-situ stress based on displacement measurement of borehole wall, including the following steps: pumping the prefluid and the sand-carrying fluid into the target interval, and injecting the biological oil displacement agent into the target interval in sequence; pumping temporary plugging agent into the target layer to implement crack plugging diverting; pumping the sand-carrying liquid into the target interval, and injecting the biological oil displacement agent into the target interval. The beneficial effect of the technical scheme proposed in this disclosure is: by injecting oil displacement agent to fracturing fluid, the temporary plugging diverting fracturing is integrated constructed with enhanced oil recovery, at the same time, it can overcome the incomplete removal of temporary plugging agent and the water lock effect of fracturing fluid caused by diverting fracturing.
