Abstract: Tahe carbonate reservoir is a fractured reservoir with karst and caves related to weathering crust. It is characterized by complex and variety of reservoir bodies, very serious heterogeneity and triple porous media flowing, which result in very difficult stable production and water control in it. Since 2001, in District A of Tahe field have taken measures for the purpose of stable production and water control (SPWC). This paper presents basic procedures for SPWC, they are, strict control of producing pressure differential prior to water breakthrough, water-coning control after water breakthrough, and pumping when unflowing;_ if pumping is not effective, water plugging will be taken, if water plugging is ineffective, combine with acid treatment, if acid treatment is unsatisfied, take sidetrack drilling or water flood test. Following these measures, obv ious effectiveness and improved production indices have been found in this reservoir.
