摘　　要：河141区块属于低孔低渗油藏,因地层能量低,须采用注水方式开发。该文研究了不同注入水水质对该块沙一段储层的损害规律及损害程度,并确定了适合其储层注入水水质推荐指标,提出了水质处理建议。He 141 block is a type of oil reservoir with low porosity and low permeability. Owing to its low formation energy, it needs to be developed by water flooding. Rule and degree of Est formation damage by different qualities of injected water are studied in this paper. It gives recommendatory criteria of water quality and suggestion of treating injected water.
