Because o f inv estm ent lim iting, the application of
tertiary o il recovery techn ique is lim ited. It is a new task
under the recent o ilfield explo itation situation to study how to
ga in the m ax imum pro fits on low er investm ent o f tertiary o il
recovery techn ique. There fore, since the reservoir substances
constantly chang es, the factors affecting exp lo itation in late
per iod o f o ilfie ld exp lo ita tion become com plex. By
d isp lacement expe rim en ts o f long cores, w e have studied the
feasib ility and the effect o f weak ge l enhanced o il recovery
coopera ted m icrob ia l enhanced o il recovery techn ique. The
study show s, th is techn ique cou ld ga in advantages and avoid
shortcom ings. So we can ach ieve the m ax imum interests and
it w ill a lso prov ide us a new w ay to perfect tertiary o il
recovery techn ique.
