Abstract:

The wear between the rod and the tubing in wells using the pumping unit has become a serious problem in oilfield. The main reasons for the wear are the well deviation, the string structure, the rodtubing assembly and the unsuitable working system, moreover, the materials of the rod and tube as well as the properties of produced fluids. The mechanism of deviation and wear was studied with the material mechanics theory, and the technical skill and application of deviation and wear prevention methods in Binnan Oil Production Plant were introduced in this paper which will be used for reference on how to improve the exploitation benefits and therecovery efficiency of old oil fields.
