| 摘 要： | 将济阳坳陷东营凹陷现河庄油田泥质岩储层的裂缝类型分为6类,研究了泥岩裂缝识别特征,分析了泥岩裂缝的主控因素是构造应力和异常压力,并且还受到沉积相带、储层岩性、岩层厚度等因素影响。现河庄油田泥岩裂缝形成于馆陶组沉积早期,正好与烃源岩大规模生、排烃期相匹配,形成了泥岩裂缝油气藏。

| Abstract: | The fractures of mudstone reservoir at Xianhezhuang ar- ea are classified as 6 types.How to indentify the mudstone fracture is studied,and the key factors to generate the frac- tures are identified as the tectonic stress and abnormal pres- sure.Meanwhile.the fractures are also subject to the sedi- mentary facies,the lithology of reservoir and the thickness of horizon.The fractures at Xianhezhuang area were genera- ted at the early sedimentary stage of Guantao formation when hydrocarbons in source rocks were generated and then expelled,thus bringing about rnudstone fracture hydrocarbon pool. |
