Segmented plugging method for horizontal well

The invention relates to the technical field of horizontal well segmented plugging, in particular to a horizontal well segmented plugging method which comprises the steps that absorptivity information of a horizontal well stratum is obtained; based on the absorptivity information of the horizontal well stratum, the horizontal well stratum is divided into a plurality of separation sections; according to the absorptivity information of each separation section, determining the components of the plugging agent of each separation section; and a corresponding plugging agent is injected into each separation section. According to the plugging agent for the horizontal well, well sections with different permeability of the horizontal well are plugged in a more targeted mode, the plugging effect is more prominent, waste of plugging materials, time and labor caused by the poor plugging effect due to the fact that the same plugging agent is adopted in the horizontal well sections with different permeability is avoided, an
