Research Of Abandonment Judgement Technology Of Tubing

Tubing and rod are important oil field equipment and materials, but also transmits power pumping wells, transmission oil must flow downhole tools. Because of its working process in the mine, in addition to extremely complex forces outside their own working environment is very poor, resulting in tubing or sucker rod failures occur frequently. Not only to the normal production and management of oil has brought many difficulties, but also the work of maintenance measures increase the amount of crude oil costs, reduce the economic benefit, and exert serious impact on the continuing and efficient oil field development.To solve this problem, the project will be based pipeline break, leak, rupture and other major rod mill and the failure mode. The actual production from the field must meet the needs of actual load conditions, based on the remaining life of metal structures based on theory. The economic, practical, efficient, conduct theoretical research and laboratory experiments to determine a reasonable sentence tubing and sucker rod inspection and material conditions of waste separation technology methods, and related testing equipment was developed which has been used for the old rod repair and provide technical support.
