水平井单井提液时机选择

提液的真正目的是要达到明显的增油效果.通过综合考虑提液能力和增油效果,借助无因次采油、采液指数分析方法,提出了水平井单井提液时机应选择在无因次采油指数递减较缓,且无因次采液指数急速上升之前的阶段.在现场实际的提液中得到了很好的印证,该提液时机选择方法对现场水平井单井提液可以起到很好的指导作用.

Opportunity choosing of increasing liquid for single horizontal oil well

The real purpose of increasing liquid is to achieve significant increased oil. This article put forward the optimal opportunity of increasing liquid based on the dimensionless oil productivity index and dimensionless fluid productivity index analysis by combined the ability of increasing liquid and increased oil effect. The opportunity of increasing liquid for single horizontal well is in the stage when dimensionless oil productivity index decline slower and before the dimensionless fluid productivity index sharp rising. The actual practice of increasing liquid also confirmed the correctness of this viewpoint. The method of this article mentioned will take good guidance for the actual horizontal well increasing liquid.
