Test of resistance in viscous fluid for the collar of wire rope sucker rod;

Application and development of technology of wire rope sucker rod pumping system;

In recent years, the wire rope sucker rod has obtained the preliminary success in the domestic oil field\'s application, demonstrated the strong vitality.

For the characteristics of wire rope flexible sucker rod,the design of heavy-duty rods is proposed.

According to requirements of wire rope for pumping oil on anticorrosive property, PP, PP + , and five kinds of nylon are compared from many aspects such as anti-ageing property, mechanical property, melt index, impact property on low temperature and anticorrosive property by a lot of test and research.
