It has been proved that when using horizontal wells to develop low and ultra-low permeable reservoirs based on stimulation,changes of pressure distribution in formation can be quite complex and may have impact on limit reserves. According to the theory of basis seepage flow about low permeable reservoirs,we analyzed the variation of the reservoirs' property after their reforms and obtained the formula about pressure distribution of steady-state seepage of a vertical well. Then by using the proper function of conformal transformation,we built the three-dimensional mathematical model of pressure distribution of horizontal wells in low permeable reservoirs after reforms. Combining with actual reservoir parameters,we studied the transmission of pressure on the horizontal and vertical plane of a horizontal well by using steady-state successive approximations. And in turn,the limit drainage radius under the corresponding conditions could be predicted. To sum up,our research would be helpful for developing the low and ultra-low permeable reservoirs more effectively and efficiently.
