| 摘 要： | 富黄探区西部长6裂缝特征及控制因素研究始终是勘探工作中的难点之一.通过对岩心和薄片中裂缝的观测统计、研究认为:宏观裂缝主要属于不受局部构造控制的区域裂缝,且以张性缝为主,垂直缝约占90％,约50％的裂缝未充填,属于开启缝；微观裂缝多属构造成因,成岩微裂缝较少,大多数微裂缝为有效缝.该区长6储层中微裂缝主要分布在浊积扇扇中边部,表现出较明显的“相控”性.滑塌构造、重力变形构造等的诱发机制可能是形成微裂缝的主要因素之一.岩性为裂缝发育奠定了基础,孔渗性变化对于该区长6储层裂缝发育有明显的控制因素. |

| Abstract: | Observation of core and thin section indicates that fractures in the Chang 6 frac~tred-type reservoir in the west Fuhuang prospecting district, Ordos basin are regional ones not controlled by local structure and most of effective fractures are microfracture. The microfractures are controlled by sedimentary facies and related to lithology, collapse and gravity structure. The fracture development is controlled by porosity and permeability. |
| Keywords: | Chang 6 fractured-type reservoir fracture characteristic Fuhuang prospecting district controlfactor |
