18号注水站油区停躺井恢复研究

Study on recovery of lying well in no.18 water injection station

随着油田开发的深入,低产低效井及停躺井随之增加,严重制约着采收率及油田效益的提升。对低产低效井及停躺井进行研究分析,制定对应的治理措施势在必行。但目前的恢复井大多以经验进行,没有系统的理论予以支撑。现根据低产无效井生产历史和油层条件,查找原层和接替层的生产潜力,结合地面、地下、井筒等状况,有针对性地分类治理,以油井停躺井和低产原因调查为主线,对长停井和低产井进行全面体检,完善档案、找准病根,对症下药、专项治理。提高油藏采收率,夯实稳产基础。

With the development of oilfield,low production and low efficiency Wells and laying Wells increase,which seriously restricts the improvement of oil recovery and oilfield benefits. It is imperative to study and analyze low - productivity and low - efficiency Wells and laying - off Wells. However,most of the recovery Wells are carried out by experience without systematic theory. Is invalid according to the stripper well production history and reservoir conditions,find the original layer and layer to replace production potential,combined with the ground,underground and wellbore conditions,targeted, classified management to the reason for low yield oil well stop lying Wells and survey as the main line,comprehensive checks on long stop Wells and low production Wells,improve the files and get the issue,suit the remedy to the case,special projects. Improve oil recovery and tamp production base.
