Abstract

Abstract: To determine the reasonable well spacing in horizontal well pattern，steadystate pressure distribution formula is derived using pseudo three dimensional method，conformal transformation and superposition principle method.The seepage field diagram of horizontal well pattern is plotted by programming.Based on the relationship between reservoir control area of a horizontal well and the well spacing of well pattern，well spacing formula is deduced.It is shown that the area near the center of interval region is not swept and is sensitive to horizontal well length，injectionproduction well spacing and well spacing.The method to determine the reasonable well spacing is proposed and it can provide an important basis for the development strategy.

Key words: horizontal well, regular rectangular well pattern, well spacing, seepage field diagram, swept region 
