Abstract: Aiming at the complex transformation of the inflow performance relationship of the huff and puff wells and the restrictive，costly analysis and limited range of application of the numerical simulation，which is usually used to simulate the inflow performance relationship，and according to the result of numerical simulation，the grey relation analysis method is used，the sensitivity of the influencing factors to the inflow performance relationship of huff and puff wells，such as cyclic steam injection volume，steam temperature，steam ratio，steam injection rate，steam soak time and so on，are studied.According to the analysis above，a computation module of the inflow performance relationship of cyclic steam stimulated wells is built，which includes all the factors above.After examination，the model is found with higher accuracy and can be used to guide field practice.

Key words: huff and puff well, inflow performance relationship, data mining, sensitivity analysis, mathematical model
