Abstract: In this paper, the current research of hydraulically fractured horizontal wells in the development of low\|permeability reservoir is overviewed. Some interesting topics, the flow mechanism of the fractured horizontal wells, the optimum of fracturing, and the comparison capabilities between a fractured horizontal well and a vertical well with a vertical fracture, are discussed. The results show that the fractured horizontal wells are better than the vertical wells with vertical fractures in the respect of development efficiency and economy. Especially, the horizontal well with transverse fracture is more preferable to that with longitudinal fracture. When the permeability along the direction of fracture is equal to or less than that along the direction of well bore, the optimum fracture number is 3～5.

Keywords: hydraulically fracturing; horizontal wells; flow through porous media; production capability
