稠油疏松砂岩,在洗油过程中存在着两方面的问题,一是易掉粒,由于是靠稠油胶结,甚至洗油后不成形,且易堵塞脂肪抽提器;二是洗油达到标准,即洗油液无色透明并用荧光灯检查显示荧光四级为止,但在驱替过程中仍有原油出现,明显洗油不净,直接影响了实验数据的真实性,从而也严重影响了利用实验资料确定解释参数的准确度。所以,对稠油疏松砂岩的洗油方法进行了探讨研究。
Heavy oil loose sandstone, there are two problems in the wash oil process, one is easy to fall tablets, because it is by heavy oil cementing, or even after washing the oil is not formed, and easy to plug the fat extractor; Second, wash oil to achieve The standard, that is, the colorless and transparent wash fluid and fluorescence test showed fluorescent fourth, so there is still crude oil in the process of flooding, obviously wash the oil is not clean, a direct impact on the authenticity of the experimental data, which also seriously affected the use of Experimental data to determine the accuracy of interpretation parameters. Therefore, the heavy oil loose sandstone wash oil methods were discussed.
