摘要

The productivity analysis of horizontal wells serves as a crucial foundation for formulating rational operational strategies, forecasting production performance, and determining the most suitable recovery method for such wells. Thus, investigating the productivity of horizontal wells holds significant theoretical and practical importance. This paper examines the computational methods for the steady-state productivity of horizontal wells, presenting the classic formula for this productivity, the binomial productivity equation for horizontal gas wells in nonlinear flow formations, and the steady-state productivity model for symmetrical multilateral wells.
