喇嘛甸油田污水注水管网的优化

Sewage Water Injection Pipe-net Optimization of Lamadian Oilfield

随着喇嘛甸油田清水注入量大幅度增加及区域钻控影响,出现了局部地区水多注不下去,其他地区水少注水量不足的问题。通过对油田内现有污水、注水管网及区域内污水站、注水站水量进行分析,对全油田低压污水管网进行改进、优化调整,通过建立区域内环状管网、区域间支状管网,实现区域内污水自产自销,区域间污水相互调用,有效解决了因区域内产注失衡而导致能耗增加的问题。

As the amount of clean water injection increases substantially and regional drilling leaves an influence in Lamadian Oilfield,some areas are so swollen that could not hold more water while water for other regions is insufficient. By analyzing the current sewage, water injection network, the amount of sewage stations and water injection plants within the district,this paper has proposed improvement,optimization and adjustment of the overall sewage pipe- net. Through the construction of intra- region looped pipe network and inter- region branch pipe network,sewage could be produced and consumed all within the region and the sewage diversion between regions could be realized,too.The problem of energy consumption resulting from the unbalance between producing and injection was solved effectively.
