<p>A flat model permeability experiment was conducted using a 7-layer rock sample from the Ordos Basin to analyze the effects of cyclic water injection, horizontal well throughput, asynchronous injection and production in the same well, and asynchronous injection and production in different wells on oil-water distribution. The results indicate that during the initial stage of cyclic water injection on the flat, the leading edge of water injection advances uniformly towards the production end, forming a fan-shaped water drive leading edge and creating breakthrough flow at the crack. Reasonable half-cycle water injection is beneficial to improving the degree of production. Horizontal well throughput can only increase cumulative oil production in the short term is about twice as high as the first cycle, and cannot significantly improve oil recovery. In the same well asynchronous injection-production experiment, the fracture spacing is small, the injected water is easy to channel, and the remaining oil is concentrated in the block near the production end corner and the middle and lower part of the plate, the spread range of water drive is narrow, and the final recovery rate is low is only 3.32% higher than the first cycle. In the asynchronous injection and production experiment of different wells, the injected water flows simultaneously from the waterflood joint to the oil production joint adjacent to the same well and the opposite side of the oil production joint, mainly in the form of relative interfracture flow. The remaining oil in the staggered asynchronous fracture injection and production experiment of different wells is enriched in a broken line shape and the water drive range of both is wide. The order of advantages and disadvantages for maintaining stable production and delaying decline is: cyclic water injection/asynchronous injection from different wells&gt;asynchronous injection from the same well&gt;horizontal well throughput.</p>
