| 摘 要： | 综合评价各种不同的解堵技术,对于指导油田生产,保证稳产高产有重要作用。油田解堵技术的评价中,存在许多模糊因素。用模糊数学的方法处理有关问题更为合理。这里用模糊综合评判的数学方法,对大庆油田南四--八区七种解堵技术的实际应用效果进行综合评价。结果表明:对于该油区目前生产阶段,热化学(Ⅱ)技术、低伤害缓速酸技术属最好类型;超声波技术和高频水力振荡技术次之;热化学(Ⅰ)技术、复合酸技术、高能气体压裂技术再次之。

| Abstract: | Comprehensive estimation of various plug-releasing technologies plays an important role in guiding oilfield production and keeping stable and high productivity. There are many fuzzy factors in the estimation of plug-releasing technologies of oilfield, so it is more reasonable to use the method of fuzzy comprehensive estimation to solve the involved problems. In this paper, the method of fuzzy comprehensive estimation had been applied to the synthetical analysis of the effects of seven plug-releasing technologies in Daqing south 4-8 area in 1995. The results show that thermochemistry Ⅱ and low-harm delay-acid technologies are the best, high-frequency hydraulic vibration and supersonic technologies take the second place, thermochemistry Ⅰ, polytene acid and high-energy gas crushing technologies take the third place for the area of the oilfield at present. |
