费尔干纳盆地东北缘A油田油藏地质特征

Reservoir Geological Characteristics of A oilfield in the Northeastern Margin of Fergana Basin

A油田位于费尔干纳盆地东北缘,紧邻延长石油的3个合作区块。A油田自苏联解体到2002年间一直处于停滞状态,地质资料缺失严重。本文利用苏联老资料和近年的新资料,对A油田的构造、沉积、储层、流体性质、油水关系等进行综合研究,总结A油田的石油富集规律,为邻近的延长石油3个区块下步勘探开发指明了方向。

A oilfield is located in the northeastern margin of the Fergana Basin,and is adjacent to the three cooperative blocks of Yanchang Petroleum.The A oilfield has been stagnated since the disintegration of the Soviet Union until 2002,and the geological data were missed.In this paper,we use the old data of the Soviet Union and new data in recent years to conduct a comprehensive study of the structure,sedimentation,reservoirs,fluid properties,and oil-water relationship,summarizing the enrichment law of oil in the A oilfield.The results indicate the direction of exploration and development for the three adjacent blocks of Yanchang Petroleum.
