摘要
目的探讨鄂尔多斯盆地华池地区长3储层特征。方法利用真实砂岩微观模型实验对储层进行研究。结果鄂尔多斯盆地华池地区长3储层为致密型砂岩,真实砂岩微观模型实验直观地显示出鄂尔多斯盆地华池地区长3储层具有很强的微观非均质性。结论砂岩的成岩作用和孔隙结构是影响鄂尔多斯盆地华池地区长3储层微观非均质性的主要原因。在低渗透砂岩中,溶蚀作用引起砂岩产生强烈的非均质性,而这些砂岩则形成长3储层的高渗带。
Aim To explore the characteristic of Chang 3 reservoirs of Huachi area in Ordos Basin. Methods Based on the authentic sandstone micromodel experiment, discuss and study the reservoirs of Chang 3 reservoirs of Huachi area in Ordos Basin. Results Chang 3 reservoirs belong to close sandstone. The authentic sandstone micro- model experiment audio-visually display the intense microanisotropy of Chang 3 reservoirs of Huachi area in Ordos Basin. Conclusion The sandstone pore structure and diagenesis are main factors influencing Chang 3 reservoirs microanisotropy. The dissolution resulted in the intense microanisotropy of Chang 3 low permeable sandstone, but this sandstone formed high permeable zone of Chang 3 reservoirs of Huachi area in Ordos Basin.
