摘　　要：针对油田小泵径管式抽油泵修井检泵作业需起出油管柱的问题,研制了一种长柱塞短泵筒结构的小泵径杆式抽油泵。该泵采用长柱塞短泵筒、双坐封结构、弧面结构的密封座环、双游动阀下置、碳化钛阀球和碳化钨阀座等技术方案,解决了小泵径杆式抽油泵的结构设计和可靠性问题。现场试验结果表明:小泵径杆式抽油泵一次性下泵坐封成功率100%,能满足低产液井使用要求,同时还可降低修井检泵作业劳动强度,减少修井占井时间对原油产量的影响,节约生产成本。该抽油泵解决了排量大与单井产液量低的矛盾,可适用于低渗透油田低产井原油的开采。Considering the issue that tubing string must be pulled out of hole during the inspection of small diameter rod pump,a small-diameter rod pump with long plunger and short pump barrel has been developed,thus eliminating pulling out of hole during pump inspection. The pump,which adopts long plunger,short pump barrel,dual packing structure,arc structure sealing seat ring,lowered dual traveling valve,titanium carbide ball and tungsten carbide ball seat,could address the structure design and reliability of small-diameter rod pump. Field test showed that the small-diameter rod pump had a 100% success rate run-in-hole and setting operation,meeting the requirements of low-yielding wells while reducing workover labor intensity and the impact of workover time on oil production,thus saving production cost.
