二、背景技术2. Background technology
微生物驱油是通过注水井向油藏注入经筛选的驱油功能菌和/或激活剂，利用驱油功能菌的生物活动或代谢产物(生物表面活性剂、生物多糖、有机酸、有机溶剂和生物气等)在油藏中与岩石、流体作用，改善流体渗流特征，提高原油产量和采收率。因此，通过有效地物理模拟手段，对微生物驱油的过程进行模拟是实现微生物驱油现场应用的前提。Microbial flooding is to inject screened oil-displacement functional bacteria and/or activators into the reservoir through water injection wells, and use the biological activities or metabolites (biosurfactants, biological polysaccharides, organic acids, organic solvents and Biogas, etc.) interact with rocks and fluids in the reservoir to improve fluid seepage characteristics and increase crude oil production and recovery. Therefore, simulating the process of microbial flooding through effective physical simulation means is the premise of realizing the field application of microbial flooding.
微生物驱油物理模拟实验是指在模拟试验区块油藏条件下(孔渗饱参数、温度、压力和矿化度等)，进行微生物驱油机理研究以及激活效果和驱油效果评价的实验，为微生物驱油现场注入工艺参数优化提供理论依据。The physical simulation experiment of microbial flooding refers to the experiment of studying the mechanism of microbial flooding and evaluating the activation effect and oil flooding effect under the reservoir conditions of the simulated test block (pore-permeability parameters, temperature, pressure and salinity, etc.).

Existing problems: (1) The intermediate container for injecting formation water, crude oil, activator and/or bacterial solution is placed in a constant temperature box, and needs to be replaced every time new formation water, crude oil, activator and/or bacterial solution Disassemble, move, replace the intermediate piston, fill liquid, and install it. During this process, the intermediate container is exposed to the air, which prolongs the subsequent heating time of the intermediate container and produces Influence; (2) The outlet metering device uses a graduated cylinder to manually measure the amount of oil and water. Therefore, not only the error of the measurement result is large, but also the gas cannot be collected, and only the oil-water mixture can be collected.
