Through the study of the relationship between the parameters of heavy oil reservoir and the well density and the recovery of steam huff and puff, a new forecasting formula of oil recovery under steam stimulation was established by regression and comparison of various formulas. Compared with other formulas, this formula takes into account the influence of well pattern density on oil recovery and has strong practical value
