帮我润色这段话：基于以上结果我们对伴生气剥离原油的微观相互作用过程进行了分析图3。我们观察到纯CO2时CO2首先撕裂油层最外层的游离油游离油迅速与CO2混溶之后CO2逐渐穿过油层向石英表面扩散；1000 ps时CO2在岩石表面已经占据了主导地位；2000 ps时最内层的烷烃也基本与石英分离开但烷烃仍成团簇状在石英附近；4000 ps时油分子大量分散、溶解在CO2中。石英附近只有很少量的油分子。CH

Based on the above results, we conducted an analysis of the microscale interaction process of associated gas stripping crude oil (Figure 3). We observed that pure CO2 first tears the free oil layer on the outermost layer of the reservoir, and the free oil quickly mixes with CO2. Then, CO2 gradually diffuses through the oil layer towards the quartz surface. At 1000 ps, CO2 has already occupied a dominant position on the rock surface. At 2000 ps, the innermost alkanes have also been separated from quartz, but still exist in clusters near the quartz. At 4000 ps, oil molecules are dispersed and dissolved in CO2, and only a small amount of oil molecules remain near the quartz. When the CH4 content increases to 25%, compared to the pure CO2 system, more oil phases dissolve in the gas phase in a single molecule form within the first 1000 ps. At 2000 ps, a large number of gas phase molecules enter the oil layer, causing significant expansion and dispersion of the oil layer. At 4000 ps, the oil layer is basically dispersed into the gas phase, but some oil molecules still remain near the quartz. When the CH4 content is 50% and 100%, only a small number of gas phase molecules enter the area between the oil layer and the quartz surface. Most of the gas phase molecules only enter the interior of the oil layer, causing the oil layer to expand, while the oil layer and the quartz surface are almost inseparable
