Dolomite small-scale fracture-cavity reservoir body fine description method

The invention discloses a dolomite small-scale fracture-cavity reservoir body fine description method. The method comprises the following steps: S1, determining an exploration range; s2, small-scale fracture-cavity distribution is determined within the exploration range delimited in the step S1; and S3, determining a small-scale fracture-cavity structure type in the small-scale fracture-cavity distribution area predicted in the step S2. According to the fine description method for the dolomite small-scale fracture-cavity reservoir body, related basic map types and specifications are formulated, a prediction process is established, and fine description, reservoir modeling and reservoir evaluation can be rapidly and accurately carried out on hole fracture distribution of a complex rock sample on the basis of few measurement parameters, short period and cost saving. 本发明公开了一种白云岩小尺度缝洞储集体精细刻画方法，包括以下步骤：S1、确定勘探范围；S2、在步骤S1划定的勘探范围内确定小尺度缝洞分布；S3、在经步骤S2预测的小尺度缝洞分布区内确定小尺度缝洞结构类型。本发明采用上述白云岩小尺度缝洞储集体精细刻画方法，制定了相关基础图件种类和规范，建立了预测流
