21、、H13-35、H12-19、H22-165中压注水系统单井调整至高压注水系统。单井调整后高压注水系统现有 34井，调整后复测数据如下：调整优化后高压注水系统机泵效率上升3.11%、管网运行效率上升4.04%、系统效率上升5.81%、注水单耗下降0. 39 kw.h/m3，所有指标均有明显上升，但 未达到分公司指定目标70%，还需查找原因挖掘潜力。2、主要存在问题是：H11-416 （哈17计）、H11-516 （哈22计）站内油压与注水干压持平压力偏高，造成整体高压系统出站压力抬升，建议两井增加单体泵增压或酸化方式， 可降低高压注水系统出站压力至 24.5MPa预测数据如下：高压数据机泵效率

25、516现运行于中压系统, 油压较低且没有低压注水流程。2、本着挖潜增效的原则，下步计划 H22-55、H362连接站内中压注水管线;H11-516、H13-17、H13-116、H13-516连接站内低压注水流程，流程改造后即可满足低压注水系统的注水量，又可使低压注水分压点由17.5MPa下调至14.5MPa,整体注水系统效率得以提升。预测数据如下:低压数据机泵效率%管网效率%系统效率%单耗 kw.h/m3现状P 96.7561.9659.944.95预计956864.44.31对比-1.756.044.46-0.64（四）、哈二站注水系统分析:哈二站注水系统注水井12井，出站压力16MPa测试数据如下：系统名称机泵效率%管网效率%系统效率%单耗 kw.h/m3哈二站90.0669.7061.744.97该系统问题主要是限制注水后大多数单井油压较低，只有吉2计H76-56油、干持平，目前日配注25方，16.0MPa注水压力已经是完成配注的最低要求，吉1计H76-47油压14.0MPa,其余单井油压均在12.0MPa以下。H76-56、H76-47使用单体泵增压或酸化方式，可降低哈二站的注水系统分压点至12.0MPa,出站压力控制在12.2MPa。哈二站数据机泵效率%管网效率%系统效率%单耗 kw.h/m3现状90.0669.7061.744.97预计9
