川东地区飞仙关储层分类及典型井精细解释

四川盆地东部,下三叠统飞仙关组是勘探的主要目标层,研究认为该层由于沉积期水体深度不同,发育三种不同类型的储层,分别是孔隙型、孔隙—裂缝型及裂缝型,由于储层类型不同,其孔、渗性能和天然气产量差别较大,钻井过程中气显示特征也不尽相同。对川东石柱复向斜建南构造XD1井进行精细解释后,认为该井飞仙关气层为一套不同类型的交互沉积层,需要进行逐层精细解释,才能分段确定储层性质及类型,准确进行分段产能预测。

Feixianguan reservoir of eastern Sichuan and fine interpretation of the typical well

Lower Triassic Feixianguan group is the main exploration target layer,in the Eastern Sichuan Basin,The study suggests that this layer due to deposition of the depth of water,the development of three different types of reservoir are porosity,pore--fractured and fractured,Different types of reservoirs,the large difference between porosity and permeability properties and gas production, drilling gas shows different characteristics.The Chuandong the pillars Synclinorium Jiannan construct XDI well detailed interpretation of that The well Feixianguan gas reservoir for a set of interaction of different types of sedimentary layers,layer by layer of fine interpretation can be segmented to determine the reservoir properties andtype,accurate segmentation and capacity forecasts.
