由KS—A抗砂增效泵及配套的KS—T携砂助抽器构成的新型抽油系统，具有抗砂磨、防砂卡、防砂埋、减少泵漏失及携砂助抽等特点。与长柱塞防砂卡抽油泵相比，KS—A抗砂增效泵的不同之处是柱塞两端装有刮砂杯，柱塞密封段有几道强磁密封环，增加了泵筒与柱塞间隙的密封性能。从现场25口井的应用情况看，对于出砂量小于1％的油井，可直接下抗砂增效泵和携砂助抽器进行生产，不会出现卡泵或砂埋泵筒；对于出砂较严重的井，应先采取化学防砂和固砂措施，然后再下携砂抗砂增效抽油系统，能有效延长油井的检泵周期。然而KS—A抗砂增效泵的泵底阀阀座及阀球材质硬度不是很高，有时会出现被刺现象。

A new sand control sucker rod pumping system comprised of sand control subsurface pump and sandcarryin device is developed Being different from the sand control subsurface pump wiht longplunger the new pumpin gsystem is provide wiht sand scrapers at the tow ends of the plunger ,and ther are ferronmagnetic seal ring s in teh sealin gsection if the plunger Field use of teh new pumpin gsystem is illustrated It is proved that the pumpin gsystem can operate well in sand wells with less pump leakage
