摘要
针对我国低渗油田的特点、自然产能低、地层压力下降快等引采收率低的现状,介绍了二氧化碳混相驱替的驱油机理、最小混相压力的确定,以及适用混相驱替油田的标准,提出了混相驱替中存在的气窜、气源、结垢等问题。
The flooding mechanism of carbon dioxide miscible flooding technology was introduced, the minimum miscibility pressure was determined as well as the suitable criteria for the miscible displacement field, some problems including gas channeling, gas source and scaling in the carbon dioxide miscible flooding were discussed.
