EXPERIMENTS AND NUMERICAL MODEL OF OIL−CHEMICAL AGENT TWO-PHASE FLOW WITH THERMAL STABILITY EFFECT AT HIGH TEMPERATURE
要約
There has been much research done concerning the thermal stability of chemical agents for crude oil exploitation; however, it is not very clear whether chemical agent thermal decomposition has a great influence on oil recovery at high temperatures. In this study, crude oil displacement experiments of cores using chemical agents with good thermal stability were conducted. A fitted equation between the chemical agent concentration efficiency and the temperature was obtained. A numerical model describing the experiment and chemical agent concentration efficiency was established. The simulation results showed good agreement with the experiment data. Under the condition of constant temperature, the flow of a chemical agent with better thermal stability can result in higher amounts of oil recovery. An optimum temperature exists that will produce the highest level of crude oil recovery with chemical agent displacement flow.
