摘要
低渗透油田水平井开采后面临着产量递减快和油井不见效等原因造成的低产问题。针对水平井开发初期储层改造不彻底的低产井,重复压裂成为有效发挥油藏潜力和提高单井产量的主要措施。本文在认真梳理影响水平井压裂效果的4类因素共28个指标的基础上,应用了科学有效的选井方法来优选重复压裂潜力井。同时,采用针对性的压裂工艺技术,水平井重复压裂现场应用效果显著,对低渗透油田推广低产水平井治理具有重要指导意义。
It is universal for horizontal well in low permeability oilfield to face the problem of low yield caused by the no effective water drive and fast production decline. Repeated fracturing is the main measure to develop the reservoir potential and improve the single well production for the low yield horizontal well which is due to the reservoir transforming not completely in the early stages of development. A scientific and effective method of selecting well is applied to optimize the potential well on basis of the 4 kinds of factors, a total of 28 indicators, which affect the horizontal well fracturing effect. The effect of repeated fracturing application for the horizontal well is obvious after by used the targeted fracturing technology,which is very important to promotion management for the low yield horizontal well in low permeability oilfield.
