原油采收率受盐水组分影响的结论是在观察研究后作出的。在本文中。用Moutray原油得到所用岩心的润湿状态。试验用的两种岩水的组分是4%NaCl+0.5%CaCl2和2%CaCl2;它们分别称作Brine2和Brine1。在整个试验中用相同的盐水,把它们的称作标准注水和标准吸入试验。在称作混合盐水试验的过程中、在那些试验中。把盐水组分变为1或多倍。在标准注水中,Brine2给出的采收率为5.5%。比Brine1的注水采收率高。从吸入速度试验看到,Brien2给出的水润湿性小于Brine1的。由于初始的和注入的盐水及初始含水饱和度选择的不同、Berea砂岩结出的Moutray原油采收率为地下原始储量(OOIP)的59%~72%。与标准注水相比。盐水组分的改变有益于采收率的提高。在Moutray/盐水/Berea采统中,如果岩心开始与Brine2平衡,其后先注入Brine1,然后注入Brine2,此时注水采收率会有相当大的提高。盐水组分对采收率的影响导原湖的类型利率化条件青囹切关系。A旧ban原油肉Brine1和Brine2的标准注水得到15%OOIP采收率的差异,但是Brine1的采收率高于Brine2,而水润湿性较小。
The conclusion that crude oil recovery is affected by the brine component is made after observational studies. in the text. The wettability of the core used is obtained with Moutray Crude Oil. The two rock water components tested were 4% NaCl + 0.5% CaCl2 and 2% CaCl2; they were named Brine2 and Brine1, respectively. They use the same saline throughout the test and call them standard and standard inhalation tests. In what is called a mixed brine test, in those tests. Change the brine component to 1 or more times. In standard waterflood, Brine2 gives a recovery of 5.5%. Water injection recovery rate is higher than Brine1. From the rate of inhalation test, Brien2 gives less water wettability than Brine1. Beam sandstone results in Moutray crude oil recovery of 59% -72% of the original OOIP because of the initial and injected brine and initial water saturation options. Compared with standard water injection. Changes in the brine component are beneficial to the recovery of oil recovery. In the Moutray / Saltwater / Berea system, if the core begins to equilibrate with Brine2 then Brine1 and then Brine2 are injected, there is a considerable increase in water injection recovery. Effect of brine composition on oil recovery The type of Lake Lebanon Interest rate conditions Barley relationship. The standard injection of Brine 1 and Brine 2 from the old banana oil resulted in 15% OOIP recovery, but Brine 1 recovery was higher than that of Brine 2 with less water wettability.
