管理区开展以沉积特征为基础的精细油藏研究，明确小层展布规律和动用状况，利用分层封隔、液控开 关等技术，通过地面控制调节，实现不动管柱换层生产，有效缓解层间干扰问题。 滨425区块作为典型的滩坝砂油藏，具有含油小层多、层间差异大、非均质性强的特点。随着开发深 入，剩余油分布愈发零散，纵向矛盾进一步加剧，层间动用不均衡问题突出，亟需深度挖掘每层潜力提 高储量动用程度。 "有的层被过度开采导致高含水，有的层却因开采不足而潜力闲置。"管理区经理孙冰认为，分采调控， 关键在于精准挖潜。针对未充分动用的低产层，他们实施分层潜力评估，建立小层档案，通过优化开关 参数、调整生产层段等措施，提升动用效率。 本报10月20日讯(大众新闻记者顾松通讯员赵强)今年以来，胜利油田鲁明公司滨南采油管理区在滨425 区块应用多互层分采技术后，11口油井累计增油突破1450吨。其中，滨425-斜12井含水从89%降至 55%，初期日增油3吨，目前累计增油420吨，滩坝砂油藏"瓶颈"得以突破。 应用多互层分采技术后，滨411-斜11井换层生产后含水从99%降至67%，日产油增加1.2吨；滨425-斜 102井含水下降24.9个百分点，日产油从 ...
