| 摘 要： | 利用测井、钻井、岩芯资料、岩石铸体薄片分析等手段，对西峰油田董志区长8-1储层沉积相、岩石学特征、储层物性特征、裂缝特征等进行深入分析。研究结果显示：沉积相变化迅速是影响该区储层物性变化较大与非均质性强的主要因素：孔隙度较低，属于低孔、低渗储层，优质孔隙少是限制该区产量的主要因素。宏观裂缝较发育，方向为北东75°，对储层有控制作用。

| Abstract: | Logging, drilling, core data, rock cast thin are used on the analysis of the Chang 81 reservoir, sedimenta- ry facies, petrological characteristics, reservoir properties and fracture characteristics in the Dongzhi area, Xifeng Oilfield. Research results show that the sedimentary facies changing rapidly is the main factors affecting the reser- voir properties variation. The pore structure is poor, so it belongs to the low reservoir property type. And also the low quality porosity is the main factors to restrict the oil production in this area. The macro-cracks developed well with 75° NE direction, which controls the reservoir development. |
