渤南油田群碳酸盐岩储层损害研究

Formation Damage Study on Carbonate Reservoir in Bonan Oilfields

碳酸盐岩和碎屑岩储层在储层特性上的明显不同,使其在伤害类型和伤害程度上也有差异,因此在储层保护研究中应充分考虑其差别,制定出适合于碳酸盐岩储层的保护措施。通过对渤南油田群碳酸盐岩和碎屑岩的储层地质特征对比,探讨碳酸盐岩储层的伤害规律,以及该类储层在保护措施上的独特性。

Differences exist in the formation damage type and degree between carbonate and clastic reservoirs due to their differences in reservoir characters. Attentions should be given to these differences in order to have the proper protection measures for the carbonate reservoir. Through comparision between the carbonate and clastic reservoir characters of Bonan oilfields, this paper probes into the formation damage law and the protection measures for carbonate reservoirs.
