本文提出了当压力高于或低于最小可混溶性压力（MMP）时，压力对泡沫驱影响的显形化研究结果。在完成CO2泡沫显形化试验时，把表面活性剂溶液和CO2同时注进用Maljamar原油饱和的玻璃微型模型里。为了研究压力和注入方式对驱替性质和机理的影响，对这些结果进行了比较。在本研究中采用两种不同类型的微型模型：调整一分层（MLAY）大调整—非均质（MHET）微型模型。在90F的系统温度下，研究压力范围为775～1320lb／in2（绝）。利用的表面活性剂溶波是在1％NaCl溶液内的1％AlipalCD－128。
This paper presents the results of the visualization of the effect of pressure on foam flooding when the pressure is above or below the minimum miscible pressure (MMP). At the completion of the CO2 foam visualization test, the surfactant solution and CO2 were simultaneously injected into a glass mini-model saturated with Maljamar crude oil. In order to study the effect of pressure and injection patterns on the nature and mechanism of flooding, these results were compared. Two different types of miniature models were used in this study: a MLAY large adjusted-heterogeneous (MHET) miniature model. At a system temperature of 90F, the study pressure range is 775 to 1320 lb / in2. The surfactant solution used was 1% Alipal CD-128 in 1% NaCl solution.
