Abstract: The first fault block of Yangsanmu Oilfield is typical heavy oil reservoir of unconsolidated sandstone and with bottom water.Located at Yangsanmu Village,the block features in complicated surface conditions,shallow kick-off points and high deviation of new wells.It is difficult to work to match raising technologies due to the complex well structure,easily sanding production,and high speed of bottom-water coning.In order to realize the normal production of highly-deviated wells of Yangsanmu Oilfield,such systematic techniques as selecting raising technologies,optimizing rods,designing pipe strings,selecting optimum working system,and reasonably controlling pressure differential are applied based on analyzing the oil reservoirs and wellbore structures of the oilfield.This is favorable for prolonging the maintenance-period and has brought good production results.It provides good experience for systematic development of other wells and enhances the development of anti-eccentric friction technologies.
