Based on the finite Fourier sine transform method and the source function method, the three-dimensional steady-state seepage equation is solved for the pressure in a cylindrical reservoir with no-flow at the top and lateral boundary and constant pressure at the low boundary.

  • 摘要：Optimum vertical location of horizontal wells in bottom water reservoir can enhance the effective exploitation of horizontal wells, stabilize the production and prolong production time without water. Based on the production equation, critical production formula and water breakthrough time formula, comprehensive effects of horizontal well location on production, critical production and water breakthrough time are studied.
