井间储层参数预测,按常规的数理统计方法,需要许多井的资料才能得以进行。作者在油藏描述中利用地质统计与分形几何学相结合的方法,开发了只有两口井条件下的井间储层参数预测方法。这个方法不仅能够预测出两井间目的层任一点的储层参数,而且可以作出两井连线上目的层的参数剖面。既丰富了储层表征的内容,也促进了油藏地质工作的数字化。

The prediction on reservoir parameters between drilling wells can only be carried out with the data from many drilling wells by convention mathmatical statistics.However.the authors developed a new method available for the prediction on reservoir parameters of only two wells,applying geostatistics combined with fractional geometry in reservoir description.By this method,the parameters at any point of certain reservoir target stratum between two wells can be predicted,even more the parametric section of target strata linked with two wells can be achieved.Therefore,it details the characterization of reservoirs and promotes the digitization of reservoir description.
