摘　　要：为了最大限度地发挥天然裂缝在油田注水开发中的作用 ,特别是为了有针对性地开展低孔低渗透油气藏的压裂投产工作 ,提高低孔低渗透储层的压裂改造效果 ,有必要认真研究地层天然裂缝的控制因素 ,搞清其分布规律 ,从而趋利避害。基于此 ,以安棚油田深层系特低孔特低渗透油气藏天然裂缝为研究对象 ,对其控制因素进行了较深入的分析 。It’ s all known that natural fissure in the low-porosity-and-permeability-zone pay the fairy important role to the permeability of reservoir.In order to make the best use of the natural fissure in the water-injection-recovery of the oilfield,especially to develop the putting-into-operation work with a clear aim after fracturing in the low-porosity-and-premeability-zone,and to enhance the effect of fracturing in the low porosity and permeability zont ,it’ s necessary to carefully study the controlling factor of natural fissure in the zone,and clearly know the regular patern of the distribution;so as to attend good and avoid harm.Considering of this,we set the natural fissure in the super-low porosity and permeability zoen in the deep interval of Anpeng oilfield as a research object,and made a fairy deep study to the controling factor,we hope through this study to set a reference for other natural fissure controlling factor of all kinds of sand and silt sections.
