在石油溶解气研究中丰度具有重要的意义。若以储量计算丰度多会出现较大偏差,甚至在采出程度并不高时使溶解气剩余可采储量和丰度呈现负值。以石油和溶解气累计产量计算丰度则可消除因年度具体情况不同带来的影响,使溶解气丰度更有代表性。溶解气丰度值在中国全国大区间表现为西北最高、海域最低,大盆地一般高于相邻的小盆地。但在同一盆地的不同单元、不同油田间,同一油区(田)勘探开发的不同时期间丰度值可能会有相当大的差异,显示出溶解气丰度的控制因素是复杂的。总体看来,石油溶解气丰度与区域富气性有较强的相关性,保存条件对其亦有直接的影响。目前我国对溶解气的研究还相当薄弱,但溶解气利用潜力很大,建议以合理的政策促进对溶解气的利用。

In the dissolved gas studying, the abundance is very important meaning. If reserve is used in the calculation, the abundance value would be deviated greatly, even the dissolved gas remaining recoverable reserves and the abundance show negative if the recovery efficiency is not high. Using the cumulative production of oil and dissolved gas abundances accrued from year to year could eliminate the impact of specific situations, thus allow the dissolved gas abundance more representative. The abundance values of Chinese regions show that that of the northwest area is the highest, the sea area the lowest, and great basins are generally higher than the adjacent smaller basins. However, in the same basin, the abundance values of different units in different fields, or of the same oil (field) exploration and development in different time, may be different considerably, indicating the controlling factors to the abundance of dissolved gas is complex. Generally speaking, the oil dissolved gas abundance is related to the gas-rich regions and also effects to its preservation directly. At present, the research on the dissolved gas in China is still quite weak, but using the dissolved gas has great potential,therefore we recommend appropriate strategies to promote its utilization.
