Abstract: To prevent rod and pipe deviation and wearing efectively, multiple side wearing resistant tools used in the past three
years are evaluated from the perspectives of echnical evaluation, application effect, ratio of performance to price, and quality assurance.
Some tools with excellent application f t a seleced in ms of ucture, ma er a, and qualit including bi-directional wearing re
sistant coupling, vane centralizer, and vitric lined pipe. Based on the mechanism analysis and countermeasures of deviation and wearing
in view of the deviated wells with high and low liquid loading, viscous oil, and high vax content, corresponding systematic measures are
applied to he field, fulfilling effectie amnt of short-period wells and providin effective measures for selecting optimum downhole
tools in the future
