Abstract: The thin-sandstone reservoir of HD oilfield in Tarim basin is characterized by dual payzones, ultra-deep and ultrathin laminar reservoir with medium-low permeability and edge water. It is developed by water injection technology of double-step horizontal wells. This paper gives the empirical formulas for horizontal well's fluid productivity index and injectivity index changing with water cut applying the relative permeability curves. The case study indicates that these formulas are practicable for prediction of injection-production capacity, rational regulation of injection-production strategy and EOR by horizontal well water flooding in this reservoir.

Key words: Tarim basin, horizontal well, relative permeability curve, fluid production index, oil production index, injectivity index, empirical formula
