Abstract

Due to the limited well test data, it is difficult to obtain effective information about deliverability in some wells. In this paper, the calibration factor of deliverability is introduced and the calculation methods of the influencing factors are studied, to establish a deliverability forecasting method. The geophysical logging static information is first calibrated by the dynamic data of the well test. Then the deliverability of the whole field is forecasted by the calibrated static data. The seismic data, the geophysical logging data at the beginning of exploration and production, and the well test dynamic data of few important wells are made the best use in this method. This method is applied in some wells in the M gas field. The forcasting deliverability results agree well with the actual deliverability. The calculation precision of the new method is high enough to meet the demand of the project design.
