Abstract : according to the problem of serious heterogeneity , conflicts among reservoirs , low energy of wells , etc . of wenmingzhai and mazhai oil fields , this paper studies and applied the technique of temporary plugging separate zone acidizing with 100 % of success , 85 . 7 % of effectiveness and 1 : 10 . 2 of input - output 文摘:针对文明寨、马寨油田非均质性严重、层间矛盾突出、油井能量低、笼统酸化酸液易进入高渗透层、卡封分层酸化应用范围窄且无法改善层间矛盾的现状，研制应用了暂堵分层酸化工艺，工艺成功率100 ，有效率85 . 7 ，投入产出达1 10 . 2 ，取得了好的效果。
The amounts of salmonella were 1 . 3 x 108cfu / ml after 20 hours in co - culturing with bi . when four strains supernatants and acetic acid - lactic acid ( 3 : 2 ) of ph4 were added to broth media to culture salmonella , it was found that the inhibitory ability of acetic acid - lactic acid was the highest , then was that of ba , bl and bbr supernatants , and the inhibitory ability of bi supernatant was the lowest 将ph值接近4的四株菌的上清液和0 . 1m 、 ph4的乙酸-乳酸( 3 ： 2 )混合酸液以一定比例加入培养基中，培养沙门氏菌，发现酸液对沙门氏菌的抑制作用最强： ba 、 bl和bbr上清液的抑制强度相近，但不及酸液； bi上清液的抑制作用最差。
