摘要
温米油田1994年实施注水,目前综合含水64.2%。前期对注入水推进、优势注水方向、注水前缘所在位置等的研究与评价,更多地依靠油藏工程师根据动静态资料和经验分析进行判断。利用注水井水驱前缘监测技术对其进行监测,可以直接得到该井的水驱前缘、注入水波及范围、优势注水方向,经综合验证准确度达85%。水驱前缘监测技术可为正确认识砂体展布、油水分布、合理部署注采井网、挖掘剩余油以及提高最终采收率提供可靠的技术手段依据。
Wenmi oilfield implemented water flooding in 1994; currently total water-cut is 64.2%. Early time study and evaluation on flood water advance, preferential waterflood direction, the position of waterflood front etc. were mainly judged by reservoir engineer who relied on statistic data and experience analysis. Using waterflood front monitoring technique to monitor water injection well is able to get waterflood front and waterflood sweep range and preferential waterflood direction of the well, its accuracy integratedly testified reached to 85%. The technique is able to provide convincible technical basis for accurately knowing sand body distribution, oil and water distribution, reasonable flooding pattern, further developing remaining oil and enhancing ultimate oil recovery.
