Bottom water coning is an important factor affecting reservoir development effect. In order to study the water cut change law of horizontal well in bottom water reservoir, based on theoretical study, numerical model for bottom water reservoir was established. Cumulative oil production, cumulative water production and cumulative liquid production were calculated to obtain the parameter b of Yuqitai water-drive curve. Then response surface method was used to study the influence of different factors on parameter b, and then obtain the influence law and order of the factors on water cut. The result has great significance for the development of horizontal wells in bottom water reservoir.
