Abstract

Abstract: The Ordovician carbonate rock reservoirs in Tahe belong to fractured-vuggy ones，the differences of reservoir volume and aquifer volume cause a big difference in natural drive energy in different types of fractured-vuggy units.Some oil wells lack natural energy，which leads to rapid decline of production and the low recovery.Water injection substituting for oil，as a new approach to exploit the carbonate rock reservoirs in Tahe Oilfield，has achieved good results.In view of the fast increased water cut caused by the rising of WOC in the late period of flooding，through comparative study on the effects of depletion drive，flooding and artificial lift，increase of the pump setting depth shows that increase of the pump setting depth can enhance the reservoir recovery and improve the development，so as to provide the basic concept for field operation.

Key words: carbonate rock reservoir, water injection substituting for oil, artificial lift, numerical simulation, effect of development, Tahe Oilfield
