沥青质在近井地带发生沉积会对石油开采带来极为不利的影响，发展沥青质沉积控制技术对于保障石油的高效开采具有十分重要的意义。介绍了油井沥青质沉积控制技术——油井沥青质抑制技术（调整生产计划法和化学抑制法）和油井沥青质解堵技术（物理解堵法、化学解堵法、生物解堵法和联合解堵技术法）的研究与应用进展，对发展油井沥青质沉积抑制技术和解堵技术提出了建议。图2 参42

The deposition of asphaltene in near wellbore zone would have seriously negative impact on oil exploration. Therefore， the development of asphaltene deposition control technology had very important significance on the security of oil’s efficient exploitation. The research and application of oil asphaltene deposition control technology of oil well was introduced，such as asphaltene inhibition technology and asphaltene blockage removal technology. The asphaltene inhibition technology included the adjustment of production plans and chemical inhibition method. While the asphaltene blockage removal technology included physical blockage removal method，chemical blockage removal method，biological blockage removal method and the combined blockage removal method. Some suggestions about the development of asphaltene inhibition and blockage removal technology were given.
