The characters of heterogeneity widely exist in shaly sand, carbonate and igneous reservoirs.

储集层的非均质性质普遍存在于砂泥岩储层、碳酸盐岩和火成岩储层中。

This class of deposits is characterized by the abundance of iron oxide in the ores and the associated intensive regional sodic alteration. They may occur in Proterozoic intracraton or Phanerozoic continental margin volcanic arcs with nearby intrusive complex or evaporite. The spatially and temporally associated intrusive rocks are magnetite-series granitoids. Mineralization mainly occurs in second order echelon structures near the main regional structure.

该类矿床以矿石中含有大量的铁氧化物且伴有很强的区域性钠质蚀变为特征，可以产于元古代克拉通内或新生代大陆边缘岛弧环境，其周围具火成岩或含蒸发盐层，时空上与之有关的侵入岩为磁铁矿系列花岗岩，矿化主要产于近区域主断裂的羽状次级断裂中。

In order to improve the precision of the reservoir prediction, the techniques of forward and backward predictions of reservoirs were used to predicate the trachyte reservoirs in Block Ou51 in Oulituozi Area, and the predicted result was used in the production to guide the arrangement of the 3 appraisal wells, high oil and gas flow was obtained in the encountered trachyte reservoirs.

为提高该类油藏储层裂缝预测的精度，应用构造正、反演裂缝预测技术，对欧利坨子地区欧51区块火成岩的粗面岩储层进行预测，并将预测结果应用于生产，指导部署的3口评价井，钻遇粗面岩均获高产油气流。
