Gel treatment is a technology to inject the crosslinked polymer into the formation to block the fractures and channels, which allows the water to divert unswept areas/zones to improve sweep efficiency.A large number of gel treatments have been successfully applied to the oilfields with fractures and channels to improve the oil recovery.Compared with the traditional in-situ gel, particle gel has been recently developed and applied in mature oilfields because they have some obvious advantages over traditional in-situ gels.In this paper, we summarize and analyze the data on the evaluation of particle gels in laboratory and field appli1cation.

考虑到现有仪器监测的不足,朱伯芳院士提出了数字监控的理念,其基本思想是基于仪器观测资料进行反分析,利用全坝全过程仿真分析,预测预报未来一段时间混凝土坝的应力状态,评估混凝土坝施工期和运行期的工作性态与开裂风险,在条件变化时辅助反馈设计,确保工程安全.本文结合工程应用实践从基本目的、主要内容和工作模式三个方面提出了混凝土坝施工期数字监控方法,从安全监测系统布设、温控施工效果实时评价、关键参数反演三个
二滩水电站中孔闸门是重要的防汛设备,在防洪度汛工作中起着非常重要的作用.原闸门控制系统投运已有14年,PLC采用20世纪90年代的MODICON A984-145,设备停产、元器件老化严重,给防汛工作带来了安全隐患,也无法满足我厂安全生产和无人值班的要求.因此立项改造,新系统采用性能更加稳定的施耐德的Modicon TSX Premium可编程控制器,并对水封动作逻辑重新设计.二滩水电站中孔闸门控
雅砻江锦屏梯级生态调度的核心目标是在尽可能降低发电损失的前提下最大程度满足河道生态流量.本研究将梯级水库作为系统,以年发电量为目标函数,生态需水量为主要的生态约束条件,建立了梯级水库生态调度优化模型,采用改进的遗传算法进行求解.选用Tennant方法和鱼类栖息地模拟法对减水河段的生态流量进行分析,得到了反映河流不同生态目标的流量序列,以此作为调度情景,系统地研究了不同生态流量调度与工程发电量损失之
两河口水电站位于四川省甘孜州雅江县境内,坝址区河谷深切,两岸基岩裸露,岸坡陡峭,阶地不发育,呈典型的峡谷地貌,施工场地条件较差.对外交通条件较差,电站建设中需修建专用对外交通公路,由于坝址下游河床存在白孜村段大转弯,根据现场实际地形条件,两河口水电站对外交通工程将设置三座跨江大桥进入施工区,在施工区内根据施工要求设置了2座跨江大桥,桥梁主要结构涉及连续刚构桥、混凝土拱桥和索道桥三种结构形式,桥梁结
孤网条件下机组运行的稳定性和控制调节能力,对保障电力系统安全、可靠运行具有重要作用.本文主要结合锦屏二级水电站在孤网运行模式下的控制方案对大型水轮发电机组的孤网控制方式进行分析和思考,并对一种优化的机组孤网控制方式进行仿真.
