本文通过实验结果解释了用于提高诸如二氧化碳驱驱油效果的新颖堵塞机理，由高渗条带或过量开采引起的气窜是影响混相驱驱油效果的主要因素。这里提到的新颖堵塞机理避免了使用水相携带堵塞剂的不便，而将堵塞剂在接由提高采收率助剂带入多孔介质，从而对高渗条带产生深部堵塞作用。该过程通过溶解聚合物或表面活性剂于注入气中，调整混合物组成使注入气在地层入口附近为单相，而当气体进入地层深部后释放出堵塞剂来，达到高渗层深部调剖自的。地层压力和温度制约着调剖深度。本文的相特性研究给定了一定压力温度条件下互溶剂的浓度。类似的相特性测量可用于任何场合下混合物浓度优化。岩芯流动实验方法可以用于模拟该深部调剖的堵塞特征，并可以得到一些有益的认识。
In this paper, the experimental results explain the new clogging mechanism used to improve the effect of flooding, such as CO2 flooding. Gas channeling caused by high permeability strata or over-exploitation is the main factor affecting the flooding effect. The novel plugging mechanism referred to here avoids the inconvenience of using the aqueous phase to carry the plugging agent, and brings the plugging agent to the porous media by the enhanced oil recovery enhancer, creating a deep plugging effect on the hypertonic band. The process dissolves the polymer or surfactant into the injected gas, and adjusts the composition of the mixture so that the injected gas is single-phase near the formation inlet. When the gas enters the deep part of the formation, the blocking agent is released to reach the deep profile of the high-permeable layer. of. Formation pressure and temperature control the depth of profile. The phase characterization of this paper gives the concentration of the mutual solvent under a certain pressure and temperature. Similar phase characterization can be used to optimize mixture concentration for any occasion. The core flow experiment method can be used to simulate the blockage characteristics of the deep profile and get some useful knowledge.
