摘要: 泌阳凹陷安棚深层系储层胶结致密,属于特低孔隙度和特低渗透率储层。储层中天然裂缝较发育,以高角度或垂直裂缝为主,裂缝性质为张性破裂和剪切破裂。采用先进的定向取心和声电成像测井等天然裂缝识别技术,定量确定了裂缝组系产状及分布。通过研究应力场在平面上的变化规律,确定了裂缝在平面上的分布特征。提出了安棚鼻状构造的沉积成因机制,并分析了鼻状构造与裂缝形成的关系。

关键词: 泌阳凹陷, 安棚深层系, 鼻状构造, 沉积成因, 裂缝识别测井, 裂缝分布

Abstract: There developed tight formations and low-porosity and low-permeability reservoirs in Anpeng deep zones of Biyang Depression.The natural fractures were well developed in the reservoir.Lots of fractures are in the form of high degree or vertical type and belong to the extension and shear fractures.The fracture identification technologies such as the oriented core technique and acousto-electric imaging log were used to get the occurrence and distribution of fractures.The analysis on reservoir depositional system indicates the genesis mechanism of Anpeng structural nose and its connection with the generation of reservoir fractures.

Key words: Biyang Depression, Anpeng deep zones, structural nose, depositional genesis, fracture identification log, fracture distribution
