摘要
在以寻找目的层的裂隙发育带为首要任务的现阶段,利用多波信息求取裂隙密度是人们最关注的问题。为了解决这一难题,笔者给出了一种拾取裂隙密度的新方法。并首次推出了各向异性因子与裂隙密度的关系。依据这一重要的关系式,可以制作出反映各向异性因子与裂隙密度关系的曲线量板,再结合各向异性因子系数剖面,可简便地拾取出裂隙密度值。实例计算表明,所得结果与实际资料吻合较好,有益于确定裂隙性储层的裂隙发育程度和裂隙带的走向,是一种实用的有价值的方法。
At the present phase during which to discover the dense fracture belt of a targetformation is considered as the most important task, fracture density determinationusing multiwave information becomes the matter people pay closest attention to.Here a new method for determining fracture density is given,which involves these es-sentials: 1)solving for a relation between anisotropic factor and fracture density; 2)making a template that embodies the relation and 3)to obtain the fracture densityvalue by using both the template and anisotropic factor section. The computation re-sult coincides with real situation satisfactorily. This method can be used to know thedensity and strike of fractures in fractured reservoir,so it is practical and valuable-
