注水井水驱前缘监测技术及应用
|
摘要
介绍了注水井水驱前缘监测技术原理。阐述了实施工艺步骤:前期收集相关资料、中期现场监测以及后期成果解释。介绍了该技术在单井水驱效果评价、小层水驱效果评价、区块水驱效果评价和注水井调区效果评价等方面的应用情况。从应用情况表明,成果解释图可以非常直观地反映油藏水驱状况,并且可以得出优势注水方位、水驱波及长度为、水驱波及宽度、水驱波及面积等数据,为研究、挖潜及注采井网的调整提供了科学依据。
This paper introduces on the principals of monitoring technology of waterflooding front for water injection well and expounds the technology step,that is collecting the relative date at earlier stage,monitoring on-site at intermediate stage and interpreting the achievement at later stage.It also introduces on the application of this technology in the effect evaluation of individual well waterflooding,substratum waterflooding,block waterflooding and the effect evaluation of water injection well block adjustment.The result shows that the achievement interpretation plot can intuitively reflect the reservoir waterflooding condition and acquire the dominant water injection direction,waterflooding swept length,width and area,which provides scientific basis for the research.
