This paper predicted the performance of the boosting pump which is the major installation of downhole boost pressure drilling technology and the quantitative relationship between working life, cost and drilling cost by means of cost analysis. It presented that the drilling cost and cycle can be reduced in popularization and application only if the optimum design target is reached by the pump. Initial qualitative, quantitative analysis and comparison were made for booster loop and relevant parameters in terms of boost pressure drilling mechanism, process requirement, optimum design target and so on. The cause of downhole mechanical rupture, seal failure and bad reliability of foreign boosting pump was analyzed. Advances in boosting pump of China were discussed as well. This paper showed that the characteristics of this key technology had paved the way for achievement of the maximum economic benefits.
