塔中11油田志留系注入水水质标准研究
JOURNAL OF OIL AND GAS TECHNOLOGY(JOURNAL OF JIANGHAN PETROLEUM INSTITUTE)（2005）
Abstract
针对塔中11油田开发的实际情况,室内研究了溶解氧、CO2、细菌对注入水腐蚀性的影响;评价了悬浮物含量、悬浮物粒径、细菌和Fe3+对岩心渗透率的影响程度,确定了塔中11油田志留系注水水质指标.试验结果表明:注入水中含氧量应≤0.5mg/L,CO2含量应≤2.5mg/L;腐生茵TGB含量应≤104个/ml,铁细菌IB含量应≤103个/ml,硫酸盐还原菌含量应≤104个/ml;悬浮物粒径应≤5μm,悬浮物含量应＜7.5mg/L,Fe3+含量应≤5mg/L.回注污水含油量应＜10mg/L.
