摘要

Rod pumping continues to be the most widely used means for artificial lift of oil wells. Because of the wide use, the methods for design and analysis of rod pumping systems are being refined and improved continually.
In this article, a computer program "MATROD" is described, which has been developed using MATLAB R2010a to simulate the API RP 11L design method for sucker rod pumping systems. MA TROD can perform a complete design for sucker rod pumping systems. It can identify a number of rod designations for a wide range of the pumping conditions. MA TROD can design hundreds of sucker rod pumping system alternatives for a given set of conditions. It arranges the output in a table and figures formats so that it can be easily manipulated for the optimization process. Decision making of the selection between the alternatives depends on the available equipment and the required pump displacement.
In order to verify MA TROD, its results were compared with the output of an existing simulator "PUMPMAX" using previously published data. It was found that MA TROD is accurate enough to provide meaningful data. The absolute average errors between the results of the two simulators for the calculated peak polished rod load, polished rod torque, polished rod horse power and pumping displacements are 1.94%, 3.06%, 2.25% and 2.56%, respectively.
Such work is an original contribution to develop a tool for solving the conceptual design problems and design of alternative sucker rod pumping systems.
