Summary:Halahatang Oilfield belonged to a vuggy carbonate reservoir, the prediction of unflowing time and flow production rate were critically important for oilfield development. The key factors were accurately predicting the unflow pressure calculation and understanding of the trend of bottom hole flow pressure, but the unflow time was influenced by the absence of specific friction parameter and less testing points or without testing of flowing pressure in the most of wells. To solve the problems of absence of calculation parameters and less testing data, by using the specific friction parameter of inverse calculation from unflowed wells and establishing the correlation between flowing pressure of different reservoirs and wellhead oil pressure, the bottomhole flowing pressure in the untested wells was estimated for accurately predicting the unflow time. The flow production rate is predicted by studying the correlation between dimensionless production and recovery percent. By using the above method, the error of unflow time can be controlled within 2 months and error of flow production can be controlled within 10%.
