Analyses and comparisons of several kinds the continuous sucker rods;

Based on characteristics of Pucheng Oilfield reservoir and production status,the continuous sucker rod techonology was used to reduce the development cost.

Since 1999, the research of carbon fiber reinforced plastic continuous sucker rod(CFRPC sucker rod) has been started in China.

Supporting technique and application of coiled rod in oil production;

The pilot test of coiled rod pumping technology;

Compared with normal rods, the carbon fibre coiled rod behaves much more advantages, such as lighter weight, better elasticity, resisting corrosion, higher fatigue limit, etc.

Followingly, the paper makes a study of the movement features embodied by this 6-link mechanism built in this press machine, and also makes a research on the effects of the changes of the structural size parameter to speed characteristics.

In this article 6-link mechanism is used for delivering label on labeling machine.

The underground working conditions is so poor that the probability of failure on Oil pump with sucker-rod is higher, which seriously affect the pump operating conditions and production.

The friction and wear properties of the nylon coating,used to protect the surface of the flexible continuous sucker rod were studied by using a pin-on-disc wear tester in the simulated oil well environment.

A new type of petroleum equipment, the flexible continuous sucker rod, highly appraised by the oil experts, has a very good application prospect because it can fully exhibit its unique excellence on machine oil extraction.
