摘要
泡沫油流是一种特殊的流动类型,由于泡沫的存在常使真正的原油产量明显小于实际计量的体积。若泡沫在新油田评价井测试过程中出现,则会造成产量过高的假象,从而影响新油田的产能评价和对储层的认识。通过对比国外某高凝油藏测试过程中有泡沫影响下的生产气油比与真实气油比的差异,进一步确认了泡沫在测试过程中的存在,进而推导出一种计算泡沫油流中真实原油产量的方法,并对产量校正前后的试井解释结果进行对比。
Foamy oil flow is a kind of special fluid state occurred in the process of heavy oil cold production commonly in China and abroad. Due to the existence of foam,the real oil production rate in the process of DST is significantly smaller than that of observed. In order to get the true oil production rate,a new formula was derived by the different GOR between the foamy oil and conventional crude in a high pour point oil reservoir. The results have been applied in well test interpretation.
