The water frominjection wells physically sweeps the displaced oil to adjacent production wells. Waterinjection wells can be found both on- and offshore.Waterflooding was born over 125 years ago and is the oldest enhanced recoverymethod. Water does not only displace oil but is used also for pressure support of thereservoir (also known as voidage replacement).Waterflood也被称为水注射是一种传统的二次采油方法，水被注入储油层将残余的石油移出。从注射井中注入的水流将有待移出的石油，推送至邻近的生产井中。通常在海上或离岸的采油平台都能看到这样的注水井。注水采油的方法诞生于125年前，是最古老的提高采收率的办法。此方法中的水应用，不只是移出残余的石油，也为储油层提供了一定的压力补偿（又名注采比）。Why choose Hach Ultra?为什么选择Hach Ultra的产品？?Full ATEX certified analyzer and oxygen sensor完整的ATEX认证分析仪和氧传感器?Sensor withstanding extreme conditions up to 100 bar传感器可承受高达100bar的极端工作环境?Sensor with specific electrodes and electrolyte allowing the measure in samplescontaining H2S传感器配以特定的电极与电解液样，可在含有H2S的样本中进行测量?Several high corrosion resistant material available for the sensor and the flowchamber (Monel ,Titanium and Hastelloy)几款高耐蚀性材料可供传感器与流通池机身选配（Monel 镍铜合金、钛、Hastelloy镍基耐蚀耐热合金）?Wide measurement range from ppm saturation levels down to 1 ppb.。量程广，可满足从ppm饱和值到低至1 ppb的测量Water quality required to maintain high efficiency良好的水质可保证采油的高效性For a waterflood operation to be successful the water used for injection must be of aquality that will not damage the reservoir rock and injection rates must be maintainedbelow the parting pressure of the reservoir. Poor water quality will result in lost oilproduction.对于成功的注水操作而言，必需保证注射用水质量，不能对储油层岩壁有任何损害，同时注入率还需要被控制在储油层压力临界点以下。如水质较差，会导致原油在生产中的流失。The proper balance between water quality and cost has to be determined. Rigorouswater quality guidelines like 98% removal of particles above 2 microns, oil 5 ppm, andoxygen 50 ppb will
