The invention discloses a shale gas productivity prediction method and device, and belongs to the technical field of shale gas exploitation. The method comprises the following steps: determining an initial value range of fracture attribute parameters and an initial value range of matrix attribute parameters; based on the initial value ranges of the fracture attribute parameters and the matrix attribute parameters, a first preset number of initial geological models are established; inputting the first preset number of initial geologic models into an oil reservoir simulator to obtain predicted production data of a first preset time period corresponding to each initial geologic model; determining a plurality of target geological models based on the predicted production data and the actual production data; respectively determining predicted production data of a second preset time period corresponding to each target geological model; and determining productivity statistical data of the target shale gas well. By adopting the method and the device, a plurality of target geological models which accord with actual geological conditions can be determined, so that more accurate predicted production data and productivity statistical data of the target shale gas well can be obtained.
Description
technical field [0001] The present application relates to the technical field of shale gas exploitation, in particular to a method and device for predicting the productivity of shale gas. Background technique [0002] With the consumption and lack of energy in the world, the exploitation of shale gas reservoirs, an unconventional energy source, has attracted more and more attention, and the prediction and evaluation of the productivity of shale gas wells has gradually become an important part of the exploitation of shale gas reservoirs. [0003] The usual method for predicting the productivity of shale gas wells is to first determine the value ranges of the fracture attribute parameters and matrix attribute parameters in the geological model according to the logging interpretation data and microseismic data corresponding to the shale gas well, and then the staff based on experience and The actual production data of shale gas is used to determine multiple value combinations o...
