摘　　要：同一注水管网中,受地层物性参数差异性影响,注水井注水压力差异大,造成注水管网能耗高、效率低下,而常规的分压注水技术存在管网改造大、投入高等问题。液压式分压注水技术可将低压井节流能耗转化为高压井注水能量,达到节能降耗目的。该技术具有管网改造小、投资低、占地面积小等特点。现场应用表明,该技术有效解决了Y3站点分压注水难题,管网效率由70.47%上升到83.79%,提高了13.32%,年节电15.9×10~4kWh电,效果明显。In the same water injection network,the injection pressure of water injection wells varies greatly due to the difference of formation physical parameters,resulting in high energy consumption and low efficiency of water injection network.The conventional partial pressure water injection technology has many problems such as large pipe network transformation and high investment.This paper presents a micro-dynamic partial pressure water injection technology,which converts the throttling energy consumption of low-pressure wells into the water injection energy of high-pressure wells,so as to save energy and reduce consumption.The technology has the characteristics of small network transformation,low investment and small footprint.The field application shows that the technology effectively solves the problem of water injection in GJ stations.The efficiency of the pipe network rises from70.47%to83.79%,increases13.32%,and the annual electricity is133.2thousand degrees,and the effect is obvious.
