At present, a well with a complex structure represented by a horizontal well and a fish bone well gradually enters a medium-high water-containing period in application, and the internal seepage rule of an oil reservoir after water breakthrough of a production well needs to be researched. Because of the complex structures of the horizontal well and the branch well, the oil-water seepage process is interfered among branches, vertical shafts and horizontal shafts, so that the actual seepage situation is further complicated under different stratum conditions, meanwhile, the difficulty of stable production is increased due to water leakage of an oil well in production, and clear seepage rules are urgently needed, and proper water control and stable production technical means are researched.
Physical simulation of complex structure well production problems in the laboratory can be broadly divided into macroscopic and microscopic categories, wherein macroscopic and sand-filling pipes, visual flat-plate models and three-dimensional physical models are representative and extensive, and microscopic and microfluidic are the most operational and representative. In the three-dimensional physical simulation model of the macroscopic scale, two models of sand filling and cementing exist, wherein the sand filling model seriously influences the physical properties of the model in the aspects of different sand filling methods, sand filling materials, proportions and the like; the cementing process of the cementing model is complex, the material requirement is high, the cementing model cannot be modified after cementing and forming, and the cementing model is not suitable for complex and changeable oil reservoir conditions. Therefore, there is an urgent need to develop a simple, easy-to-prepare, high-repeatability, multi-purpose physical model capable of simulating strong heterogeneity, so as to study seepage rules of wells with complex structures under various stratum conditions and guide on-site process optimization.
