Abstract: Based on diversified artificial lifting process and a large amount of oil and gas wells, including the present conditions of deflecting wells, low-yield wells and highwater-cut wells, as well as the technologicaldemandofengineers,thefirstsetoflarge-scaleweb-baseddiagnostic anddecision-making software was successfully developed with our independent intellectual property right. It can satisfy the need for optimization of design, diagnosis of working conditions and management of production for more than 80 percent of China’s oil and gas wells. It can be put on line for data sharing. The latest industrial technology was integrated into this software to create the way to optimize the quantitative lifting method, make a breakthrough in 3D mechanical analysis of wellbore, come up with the design conception on coordination of production, energy consumption and service life and the conception on performance of the equivalent system, and establish the new method for appraisal of the system efficiency. The software reached the international advanced level. With good results of field application and reduction of energy consumption, the system will become the effective tool for optimization of design and management of production.
