摘要: The invention relates to thermally stimulated oil recovery in horizontal wells, namely the methods for estimation of Steam Assisted Gravity Drainage (SAGD) process characteristics. Method SAGD characteristics is characterized by steps measuring temperature along injection well, steam quality and rate at inlet estimating pressure distribution profile using data obtained, obtained combined with ID well model losses wellbore heat exchange between tubing annulus. used as an input parameter a set 2D cross-sectional analytical models taking into account reservoir overburden formation properties impact on production parameters are estimated basis energy conservation law condensed hence fluid changing time.
