The present invention discloses a method for reducing water and increasing oil production in a horizontal well of a dual-medium oil reservoir and a completion structure. The method for reducing water and increasing oil production in a horizontal well of a dual-medium oil reservoir comprises the following steps: S1, determining the filling pressure; S2, injecting a filling fluid with microparticles into the annular space between the horizontal well and the oil layer in which it is located, until the pressure in the annular space reaches the filling pressure, and at the same time fracturing the oil layer to form a tree root-shaped fracture cluster in the oil layer; S3, maintaining the filling pressure, and continuously injecting the filling fluid until the microparticles fill the annular space and the fracture cluster. In the present invention, by combining fracturing with microparticle filling, the oil production of the horizontal well is further increased without substantially increasing the water production and the production pressure difference, thereby achieving reducing water and increasing oil production.
