【摘要】开发初期海上油气田钻井少,采用基于地质统计学的储层地质建模方法难以达到理想效果；但海上油气田地震数据较完整,因而有利于探索基于地震驱动的建模方法.通过地震数据体推演储层空间变化规律,再以井为条件求取空间估计参数,进而形成了基于地震驱动的海上油气田储层地质建模方法.应用结果表明,这种以地震数据为主体的建模方法有效利用了地质模式作为建模过程的约束,较好地克服了传统地质统计学的以井为核心且在井少时难以建立较为客观的储层地质模型的弊端,为海上油气田开发前期储层地质建模提供了一种更为客观和便捷的方法.%The geological modeling of reservoirs based on geostettstics tan not be efficient for off-shure fields in early development due to less drilled wells.

The reservoir space changes were predicted from seismic data volumes, and the space estimate parameters were calculated at wells, then forming a method of geological reservoir modeling based on seismic drive for the offshore fields, Its applications have shown that this modeling predominated by seismic data volumes can efficiently make use of geological models ns a constraint on a modeling process, and hotter avoid (he shonconings of the traditional
