【 摘 要 】
In the traditional optimization design of multi-stage fracturing in horizontal wells, the rock mechanics and stress profiles of the vetical section of horizontal well or other vertical wells near the perforated cluster are usually borrowed. In the strong heterogeneity reservoirs, there is a large deviation between the design results and the microseismic monitoring results. In this paper, based on the three dimensional geological model of reservoir, the stress and the rock mechanics parameter model are builded, the stress and rock parameters of vertical profile at each perforation center are extracted, we can evaluate the difficulty of fracture extending in different position, by adjusting the number of perforations to achieve the best stimulation effect.
