- Hydroelectric simulation is an important physical simulation method, providing a direct way to study the flowing law of fluid in reservoir. This paper carried out the hydroelectric simulation experiments to study the influence of growth of natural fracture, half-length and conductivity of artificial fracture on the productivity of oil well. The results indicate that: under the same permeability, with the increase of half-length of artificial fracture, the productivity of the oil well will increase, but when the length reaches a certain degree, the increasing degree will decrease, and the proper length of artificial fracture should be selected combining the numerical simulation results for the consideration of water cut; under the same permeability and half-length artificial fracture, the more the number of the natural fracture that link to the artificial fracture, the larger the productivity of the oil well; under the same reservoir condition and fracturing scale, the larger the conductivity of the artificial fracture, the higher the productivity of the oil well. The studying results provide theoretical references for studying the stimulation mechanisms of hydro fracturing, and checking the results of numerical simulation.
