一种致密气藏水平井的产能提升方法
By acquiring logging-sensitive parameters and rock mechanics parameters, a comprehensive index model is constructed. Combined with the synergistic evaluation of geological sweet spots and engineering sweet spots, the fracturing stimulation parameters are optimized, solving the problems of large single-well production differences and insufficient reservoir identification in traditional methods. This enables efficient development and production capacity enhancement of horizontal wells in tight gas reservoirs.
