在此次研究中提高原油采收率(IOR) 方法采用流体注入方案, 包括: 水驱、混合气驱(以烃类、CO2 或氮气为注入剂)、非混合气驱(烃类注入剂)、强化水驱(表面活化剂、聚合物或碱水注入剂)、蒸汽驱(包括蒸汽辅助重力驱油) 和火烧油层。通过81个油气藏的相关数据, 并利用商业化软件包对每个油藏进行可适性筛选。经过筛选的油藏方案还需进行采收率和方案效果计算, 预测实施提高采收率措施的时机、相关费用和相应的技术风险。提高采收率方案按采油量、每桶费用、原油重度以及集采油量、费用、实施时机和风险为一体的综合标准排队, 优先选择有潜力的提高采收率方案。
In this study, the method of enhanced oil recovery (IOR) uses fluid injection schemes including waterflooding, mixed gas flooding (using hydrocarbons, CO2 or nitrogen as injecting agents), unmixed gas flooding (hydrocarbon injecting agents) , Enhanced Water Drive (Surfactant, Polymer or Base Water Injector), Steam Drive (including Steam Assisted Gravity Flooding) and Fire Burning. The data from 81 reservoirs were used and each reservoir was screened for suitability using commercial software packages. After the selected reservoir program also need to conduct recovery and program effect calculation, predict the implementation of measures to improve recovery timing, related costs and the corresponding technical risks. The enhanced oil recovery program will line up with comprehensive standards such as oil production, cost per barrel, crude oil gravity, oil recovery, costs, implementation timing and risks, giving priority to potential enhanced oil recovery options.
