The invention discloses an oil and gas well fracturing test device and method for simulating a real stratum environment, and belongs to the technical field of oil and gas well fracturing tests, and the device comprises a high-pressure rock core container, a high-pressure injection system, a rock core X-axis loading system, a rock core Y-axis loading system, a rock core Z-axis loading system, an acoustic emission system and a data acquisition control display system. The invention further discloses an oil and gas well fracturing test method for simulating the real stratum environment. According to the technical scheme, the size of the rock core sample reaches 500 * 500 * 500 mm, and the test result is more accurate. Different horizontal ground stresses can be applied to the upper part, the middle part and the lower part of the rock core sample at the same time, the shearing stress condition is simulated, and the actual rock stress condition can be simulated more truly. The acoustic emission probe is in direct c
