摘　　要：在泵下增设一个新装置，使抽油泵上下运动时，油管产生弹性伸缩。利用该伸缩引起的上下腔空压力变化，便可将化学溶剂或稀油定量掺入稠油井或高含蜡井泵下，并随井液进入泵中，从而实现了稠油井或高含蜡油井定量掺液的目的。To add a new unit under the pump,it makes the oil tube telescopes elastically as the oil well pump moves up and down. Pressure changes in upper and lower cavities caused by this telescoping make it probable to blend quantitative chemical solvent or light oil into a position under the pump of heavy oil well or high wax content oil well. The liquid will enter the pump alone with well fluid. Thus,the goal of quantitative liquid blending in heavy oil well or high wax content oil well has been realized.
