The Study Of Xinli And Xinbei Oilfield Extending Maintenance-free Period Technology

Oil maintenance-free period is a measure of an oil field development level of block orflag. Extending oil maintenance-free period, you can reduce the time the maintenance job,while reducing maintenance costs and increase the rate of oil production, reducing cost tonsof crude oil production. Therefore, extended maintenance-free period is every field goal topursue.Xinbei and Xinli oilfield is typical of low-permeability oilfield.Bad geologicalconditions restricts the extend of maintenance periods of the oilfield.According to geological conditions of Xinbei and Xinli oilfield,this paper first analyses thefactors influencing the maintenance-free period. For each the factor, it propses appropriate solutions andpurposeful implementation in some wells. On the technical measures for long-term tracking of oil wellsand analysis of every job well, so find the new legislation and new technology to extend maintenance-freeperiod, to guide the production of oil field.
