摘　　要：通过对牛东卡拉岗组压力等值图的分析发现,卡拉岗组轴部区平均地层压力偏低,翼部区较高,油井附近偏低,水井附近压力较高。从前期五个注水井组取得的初步效果,认为注水开发技术对于牛东火山岩油藏是可行的,注水方向与裂缝方向的关系制约着油井见效见水程度。根据研究结果,提出了下步技术对策,为牛东火山岩油藏高效开发指明了方向。Through analyzing pressure contour diagram of in axial region of Kalagang of oil wells is low, previous five water Kalagang formation, it is found that average formation pressure formation is low, compared the high average pressure in limb, and the pressure in the vicinity compared the high pressure n the vicinity of water producer. Based on the initial effect taken from flooding well groups, it is thought that it is feasible to adopt water flooding in the development of volcanic reservoirs of Niudong. Relationship between waterflood direction and fracture direction constrains the effect and water breakthough of oil wells. According to the findings, next technical countermeasure is proposed, which gives the guidance for the high efficiency development of volcanic reservoir in Niudong.
