摘要
介绍了一种低软化点沥青粉。室内评价试验和现场应用表明,与常规沥青粉相比低软化点沥青粉在软化点、分散度等方面有显著特点,具体表现为它既能在泥浆中高度分散又能在特定温度下软化,应用在屏蔽暂堵技术中能明显提高油层保护效果。
Low-softening point asphalt LFT-70 is developed to improve the effect of shielding temporary plugging technology. Tests indicate that LFT-70 can both disperse properly in mud system and soften in a given temperature. Examples at 2 wells are given.
