摘要
任丘油田雾迷山组油藏,是一个缝洞十分发育的双重介质块状底水油藏,初期产量很高。油井一旦见水产量下降很快。开发过程中采用什么措施减少油田产量递减,提高开发效益,是十分重要的。本文介绍了任丘油田初期采用少井高产,开发过程中逐年补打调整井,生产中不断进行酸化、卡水、堵水及堵、酸、抽等综合措施,取得了较好的开发效果,不但增产了油量,而且提高了原油采收率。到了开发后期,在水淹程度很高的情况下,如何挖潜,本文提出了多方面的办法,有待实践进一步证实。
Wumishan reservoir in Renqiu oil field is an extensively fractured double porosity massive oil reservoir underlied by bottom water.This reservoir is prolifically produced in its early development stage,and production declines rapidly as water breakthrough occured.It is,therefore,very important to take correct measures to slow down the production declining rate so as to increase the efficiency of oil field development.This paper gives a descrip- tion of a combined technique including infill drilling,and continuously aci- dizing,water shut off,as well pumping.Better development results are obtained.Production rate is increased,while the recovery efficiency is in- creased as well.This paper gives also suggestions of some measures to be applied in the later highly water cut development stage and these will be identified by field practice.
