本文从圆形、复合、双孔介质油藏中Laplace空间上,考虑井筒存储(Co)及其表皮的井底瞬时压力着手,来构造圆形封闭或定压或无限大地层中的无量纲井底压力及其导数的表达式。利用叠加原理给出地层中有单一断层或供给边线,以及河道状油藏,U形油藏,矩形油藏等井底压力及其导数的双对数图。 In this paper, from the Laplace space in circular, composite and two-hole media reservoirs, the borehole storage (Co) and its epidermal bottom hole instantaneous pressure are used to construct the non-dimensional wells in a circular closed or constant pressure or infinite formation The expression of bottom pressure and its derivative. By using the principle of superposition, a double logarithmic graph of single fault or supply edge in the strata, as well as the bottom hole pressure and its derivatives such as river-shaped reservoirs, U-shaped reservoirs and rectangular reservoirs, is given.
