Abstract: Taking a fracture-cave carbonate reservoir with bottom water in some ancient buried hill as research subject, based on analyzing shut-in coning well selection conditions of single wells in high water cut stage and optimizing technical parameter, new evaluation indexes were proposed to improve the existing evaluation indexes by adopting comprehensive evaluation method. The current index system has some problems, for example, index system is not perfect; some indicators are not unreasonably determined and quantify and refinement degree of some are insufficient. The new system is include three effect evaluation indexes for well shut-in coning and nine geological well selection conditions and technical parameters, which could be more scientific, more real to reflect the actual situation. In conclusion, oil wells that have prefect shut-in coning effect should be preferable; the moderate effects wells are carefully chose and the poor effect oil wells should be abandoned when shut-in well and coning at high water cut stage. This method could provide reference to similar block or reservoir well shut-in and coning at high water cut stage.
