Abstract: This paper introduces the deducing ideas and processes of steady?state productivity formulas for horizontal wells, and compares the commonly used formulas. Through the analysis, it is indicated that there are loopholes in the process of deducing the productivity formulas for horizontal wells, which should be corrected. There are little differences among the modified formula, Borisov’s formula, and RenardDupuy’s formula in the calculation results, thus providng the validity and practicability of the modified formula, and realizing the unification of productivity formulas for horizontal wells in form
