针对 H88区块腐蚀结垢较为严重的现状，进行采、注系统水环境理化指标和微生物种群数量分析，并在此基础上开展室内生物反硝化抑制 SRB（硫酸盐还原菌）的可行性研究。结果表明，SRB 和硫化物是引起 H88区块腐蚀结垢严重的主要因素，从 H88区块油井采出水中可以筛选到内源反硝化细菌（命名为 JS13-1，粘质沙雷菌），生物刺激可以改变采出水微生物群落结构，刺激反硝化细菌的生长。

In views of serious corrosion and scaling of Huang88 area,it was carried out to analyze water physicochemi-cal data and microbial populations of the injection -production system.On the basis of above analysis,a feasibility study of biological corrosion protection was implemented in Huang -88 area of Jiangsu Oilfield.The results showed that the severe corrosion and scaling of Huang88 area was caused by SRB and sulfide mainly,and the indigenous denitrifying bacteria (named as JS13 -1,serratia marcescens)could be isolated from Huang88 area.Therefore,the biostimulation method can change the produced water microbial community structure,and stimulate the denitrifying bacteria growth.
