安徽油区挖潜潜力分析

Analysis on Tapping the Potential in Anhui Oilfield Region

安徽油区为一系列构造成因的小断块群组成,构造演化与沉积背景特征决定了成藏模式。区内构造破碎,断块面积小,储层“三低”特征明显,挖潜难度大。从油藏成因入手,依据对油气运聚成藏规律的认识和勘探开发实践中取得的实际资料,通过对已发现的含油断块储油丰度与相关地质因素之间的关系分析,从垂向和横向上进一步认识油气分布规律,探索老区挖潜方向,找出可能具有潜在挖潜价值的潜力区,以增强老区增储上产能力。

Anhui Oilfield Region is composed of a series of structural genetic and small fault blocks.Its reservoir-forming modes are determined by structural evolution and depositional background.Within the region the structure is broken,fault block area is small,the reservoir has 'three low characters',and it is hard to tap the potential.To study starting from reservoir genesis,based on studying the reservoir forming laws and the data obtained from oilfield exploration and development,the relation between oil-bearing abundance and identified oil-bearing fault blocks is analyzed for recognizing the oil-gas distribution laws vertically and longitudinally to search for the direction of tapping the potential for the old oil region,find out beneficial areas and enhance the capacity for increasing reserves in the old oil region.
