Abstract: The mathematical models for describing behaviors of pumping nit,pump,tubing string and the compound system were set up, and the corresponding simulation models were established,according to the systematic dynamics.On this basis,the software for simulating the working behaviors of rod pumping system was developed on the principle of the modularization.The databases of oil well,pump valve, base oil and pumping unit were set up.The operation performances of rod pumping system under different working conditions, different swabbing parameters and different system configure were simulated.The simulation models and simulation software were verified by the use of unit experiment and the spot testing.The calculation results accord with the practical production.These models are applicable to practice.

Key words: rod pumping system, mathematical model, mathematical working behavior, mathematical simulation calculation, software development
