The crude oil in the regions of 6、North10 and 12 is super heavy oil which is high sulfur content、high viscosity and high wax content in Tahe Oilfield ,Especially in the region of 12,The average density of crude oil reached 1.0259g/cm?and the viscosity reached 300000mPa.S.Oil wells which are in the above regions have risk of coagulating tubing in initial stage of oil testing. Therefore, The paper present a set of new technology of anti-coagulating tubing. The results of laboratory test and field evaluation show that this technology obtains a favorable effect.
