摘要

针对大庆油田三元复合驱现场实施过程工艺参数难以确定的问题,基于北二区东部油层储层物性参数,通过填砂模型室内驱替实验,研究三元复合驱过程中各组分质量浓度、剪切降黏和界面张力变化规律,并通过数值模拟研究三元复合驱动态条件下各组分的吸附滞留规律。实验结果表明:三元复合驱的各类组分质量浓度均随运移距离的增加而降低,随注入量的增加而升高;运移20%距离时溶液黏度损失约60%;驱替前缘油水界面张力值高于10^-2mN/m。数值模拟结果表明:三元复合驱溶液各组分吸附滞留主要集中在近井地带,在运移20%距离时表面活性剂、碱和聚合物的损失量分别为80%、25%和14%;储层渗透率越低,吸附滞留损失越严重。该研究可为指导大庆油田北二区三元复合驱开发技术调整提供数据依据和理论指导。

Abstract

To solve the problem that it is difficult to determine the process parameters during the field implementation of ASP flooding in Daqing Oilfield, based on the reservoir physical parameters in the east of Block Bei 2, the mass concentration of each component, shear viscosity reduction and interfacial tension change in the process of ASP flooding was studied through the laboratory displacement experiment with sand filling model, and the adsorption and retention law of each component under the dynamic condition of ASP flooding was studied by numerical modeling. The experimental results showed that the mass concentrations of each component of ASP flooding decreased with the increase of migration distance, and increased with the increase of injected amount; the loss of solution viscosity was about 60% at 20% migration distance; the oil-water interfacial tension was higher than 10^-2 mN/m at the displacement front. As indicated by the results of numerical modeling, the adsorption and retention of the mass concentration of each component of the ASP flooding solution were mainly concentrated in the near-well zone, and the losses of surfactant, alkali and polymer were 80%, 25% and 18% respectively at 20% migration distance; the lower the reservoir permeability, the more serious the adsorption and retention loss. This study provides data basis and theoretical guidance for the adjustment of ASP flooding technology in the development of in Block Bei 2, Daqing Oilfield.
