摘要
沈阳油田是我国最大的高凝油生产基地,长期回注不合格污水,导致地层污染严重,给油田有效注水带来困难。为了有效解决这些问题,强化了沿程水质治理、地面管网管理、作业措施方案管理、注水井动态监测管理,完善了低渗区块配套注水工艺,有效地提高了油田注水质量,强化了注水基础管理工作,各项指标有了较大幅度提高,与2011年同期对比年累计增油4.2×104t。
Shenyang Oilfield is the biggest manufacturing base of high-pour point oil in China. Long time re-injection of unqualified sewage has resulted in serious formation contamination, which brings difficulty to the effective injection. To solve the problem, the management of the water quality, ground pipe network, operation measures and dynamic monitor of injection wells has been enhanced, and the water injection technology for low permeability blocks has been improved. As a result, the basic management of water injection has been promoted and the quality of water injection improved effectively. All the indexes have been upgraded and the total increase of oil production in 2012 reaches 42000 ton.
