The Technology Research Stable Of Xi Feng Oilfield

Xi Feng oilfield is one of minority of low-permeability which are found in recent years,especially to the increasing and stability of Changqing Oilfield. But in the development ofrecent years, some questions influenced the efficient development of oilfield, like, the speedof capacity dropped quickly, water rised suddenly of part wells, and plugging wells increasedyear after year, so the continuous stability is difficult. The paper analyzed the dynamic variationof capacity, dissected the essential and difficulties of stability,researched the pluggingmechanism of wells,tested13items of technology of stability through combining the reservoircharacteristic of Xi Feng oilfield. Thus evaluated the suitability of7items of technology, andproposed the countermeasure of research ideas and the direction of technology research of XiFeng oilfield in the future.
