| Abstract: | The paper analyzed the features and reasons of tubing and rod eccentric wear in middle-later period of Huanxiling oilfield development, and put forward preventive measures of eccentric wear. At the same time, the technical principle and technical characteristic of bi-directional protected box coupling were introduced. Through field application, the bi-directional protected box coupling technology solved effectively the tubing and rod eccentric wear problem, reduce the accident of break off, dropout and leakage of tubing, and obtained good economic benefit. |
