摘要
随着水平井开发技术在采油三厂的大规模应用,开发矛盾逐渐显现,由于天然裂缝、人工裂缝以及非均质性等因素,容易造成部分层段注水突进,水平井部分层段水淹,由于水平井井网局部水井密集,水平井与定向井交错分布,井网不规则、不完善,导致水平井区域油水对应关系复杂,难以判断水淹层位,影响单井产能。动态表现为高液量、高含水,日产油量较低。为提高水平井单井产量,整体提升采油三厂水平井开发效果,因此水平井找堵水技术研究实验,取得较好效果。
With the large-scale application of horizontal wells in the oil three factory, devel- opment contradiction appears gradually, as the natural fractures, fracture and heterogeneity factors, easy to cause the partial layer water injection advance, flooding horizontal well sec- tion section, due to horizontal wells dense local wells, horizontal wells and directional wells staggered distribution, well, not rules is not perfect, resulting in horizontal well regional oil- water relationship is complex, it is difficult to judge the impact of water flooded layer, single well productivity. Dynamic performance for high volume, high water cut, oil production rate is low. To improve the production of the horizontal well, the ascension of the whole oil three factory development result of the horizontal well, the horizontal well water shutoff technology experiment, achieved good results.
