Abstract:

In view of the problems of roof bolt downpass difficulty existing in traditional beam pump production with tubingless production system，the stress situation of oil pumping roof bolt of hydraulic feedback pump in the up and downpass is analyzed，and the roof bolt dynamics analysis model of hydraulic feedback pump is set up.Based on the model and optimization design technology of production system，the major influencing factors of system operation including stroke，pump diameter and oil viscosity is analyzed，and the general law of pumping parameter selection of this technology is obtained.The contrasting analysis with traditional pump is carried out through practical example，hydraulic feedback pump stress in roof bolt，torque power of pumping unit and the roof bolt fatigue intensity etc.may all well improve operational mode index.Also，it can improve the economic level of oilfield production.

Key words: production technology, tubingless, hydraulic feedback, mechanic analysis, reservoir development
