为分析地热井放喷试验获得的变流量下的压力数据,根据Duhamel原理将变流量时的井底压力表示为单位流量下的压力和流量的褶积,使用反褶积方法计算出单位流量下的压力数据,再使用压力及导数试井分析方法反演出热储的渗透率等流动参数,从而建立地热井放喷试验数据反演的理论和方法,并使用反演出的参数求解渗流方程得到流量的变化规律。最后使用该方法分析四川某地热井的放喷试验数据并进行产能预测。 In order to analyze the pressure data of variable flow rate obtained from the discharge test of geothermal wells, the bottom hole pressure at variable flow rate is expressed as the convolution of pressure and flow rate per unit flow according to Duhamel’s principle. The deconvolution method is used to calculate the pressure drop per unit flow rate And then use pressure and derivative well test analysis method to reverse the flow parameters of thermal reservoir permeability and so on, so as to establish the theory and method of geothermal well discharge test data inversion, and use the retrieved parameters to solve the seepage equation to obtain the flow rate The law of change. Finally, the method is used to analyze the discharge test data of a geothermal well in Sichuan and forecast the capacity.
