人工边水驱技术在江汉油田的应用

Application of Manpower Edge Waterflooding Technology in Jianghan Oilfield

人工边水驱是老油田低成本开发的有效调整方法之一,但缺乏有效潜力筛选标准及技术指标。借鉴胜利油田的人工边水驱技术,结合江汉油田实际,利用油藏工程及数值模拟方法,从油藏、地面、工程三个层次建立了适合江汉油田的人工边水驱潜力区块筛选标准,开展了区块潜力评价及开发模式优化,并优选浩7-4井区进行了现场推广试验,效果良好。该标准仅能评价各区块是否适合应用人工边水驱技术,难以直观评价各区块应用该技术的潜力大小,有待进一步完善。

Manpower edge waterflooding is one of effective adjustment methods for low cost development of old oilfields. But it is short of effective potential screening criteria and technical index. Using manpower edge waterflooding technology of Shengli Oilfield for reference and combining reality of Jianghan Oilfield, this paper establishes suitable manpower edge waterflooding potential block screening criteria from three lev- els of oil deposit, ground and engineering with the help of reservoir engineering and numerical simulation method, launches block potential evaluation and development mode optimization and carries out site sprea- ding experiment in Hao 7-4 wellblock, achieving a good result. This criteria can only evaluate whether each block is suitable for application of manpower edge waterflooding technology. It is hard to evaluate di- rectly its application potential. Therefore, it needs further improvement.
