Abstract: In this article a three dimension diagnostic model for sucker rod pumping systems of directional well has been developed,based on the farce analysis of rod,fluid and tubing.A numerical solution has been given by using an implicit finite difference method with the help of computer.Performances of some directional wells in Sazhong oil field have been diagnosed and the results are consistent with those of pumping tests.
