大庆外围油田油井捞油界限研究

尽管提捞采油更适合于低产新建产能井和零散油井，可大幅度降低投资和成本，提高经济效益，但并不意味着所有低产井和低效或无效井转捞油后都有经济效益。为此，以油藏工程理论为基础，通过全面总结捞油实践，提出油井捞油或抽油转捞油经济极限产量和含水经济界限确定方法，并提出了计算公式，指出了主要影响因素。该方法简便适用，为确保大庆外围油田经济有效的开展提捞采油工作和提高外围油田开发效益提供了技术依据。

Study on Oil Wells' Bailing Limits of Daqing Peripheral Oilfields

Although bailing exploitation is more suitable for the exploitation of low output oil wells drilled newly or distributed dispersively,which can reduce investment and cost to a great extent and raise economic profit,it does not mean that all of the low output and low profit oil wells or low output oil wells without profit gain economic profit after turning into bailing.Therefore,on the basis of reservoir engineering theory,combining with practice of bailing,setting up the method and calculating formulas of the economic limit output and water cut economic limit of bailing or pumping turning into bailing oil well,point out primary impact factors.This kind of method is very simple and practical.For the sake of ensuring Daqing peripheral oilfields to develop bailing effectively and raising economic profit,it offers technological basis.
