随着生产的进行，TK305井原油物性发生改变,从生产前期乳黄色凝析轻质油,变为褐黄色凝析轻质油,再后来变为褐黄色凝析油和黑色稠油;由于出现这种变化,该井无法正常生产。针对该实际问题,提出了应用掺高温沥青分散剂防治稠油方法,并在实验基础上对该井实施解堵工艺,取得了一定成效。

The oil properties in Well TK305 change with production, from the milk yellow condensate light oil in the early stage of production through the brown-yellow condensate light oil to the brown-yellow condensate oil and black heavy oil. Because the oil properties have changed, this well cannot produce normally. Aiming at this practical problem of production, the technology of controlling heavy oil by mixing high-temperature asphalt dispersing agent is presented. Based on the experiments, this well is conducted by broken down technology, achieving some effects.
