中文摘要：
利用现代录井技术得到的地层参数,根据不同井型建立地层中不同流体的渗流方程,对其进行无量纲化和Laplace变换,应用数值Laplace反演技术计算出油气井的产能曲线（IPR曲线）.计算的IPR曲线与实测数据吻合较好,从而验证了方法的可靠性,扩展了录井数据的使用范围.作为实例,分别计算了油井和气井的产能预测结果和不同时间下的IPR曲线.
英文摘要：
Using the parameters from modern logging well technologies,the equations,which have been conducted by dimensionless and Laplace transform,of different fluids in the formation were presented according to different types of wells,and the index of productivity ratio curves（IPR） was calculated by numerical inversion of Laplace transforms.Comparison with the actual data shows that they well matched the real productivity data,suggesting that the method is effective.The data of an oil well and a gas well were handled respectively,and the productivity forecasts and IPR curves were given.
