摘要
针对油田井底落物和地层出砂加剧,造成检泵作业频繁的问题,研制了可环空测试防落物抽油泵,实现了不停井环空测试技术,同时使得进入油管内的落物和砂粒得到有效疏导,从而有效延长了检泵周期,降低了采油成本。
For aggravation of falling objects in the oil well bottom and sand which caused pump de- tection frequently, subsurface pumps with annulus testing falling object-proof structure was de- veloped. The lus testing ogy did not production, instead, it dredged falling objectsand sand in tubing effectively,thus prolonged maintenance interval of pump and cut down produc- tion cost.
