There is a bottom water in the A2 6 horizontal well in the QHD32-6 oilfield. To determine a reasonable production yield, it is necessary to determine the critical production value of bottom water coning. According to the specific parameters of A2 6 horizontal well in QHD32 - 6 oilfield, the formation mechanism of water coning in horizontal well of bottom water reservoir is analyzed and several mathematical models for calculating critical production of bottom water coning are analyzed. According to the actual conditions of oil reservoir, The influence of the two models on the critical output, such as vertical permeability, oil-water density difference, horizontal well location and so on, has been analyzed, which is of great significance to the design of production well for A2 6 well
