摘　　要：利用测井、岩心以及薄片等资料,对川东北地区通南巴构造带飞仙关组第三段(简称飞三段)储层的基本特征和控制储层发育的主要因素等进行了研究。研究表明飞三段储层为鲕粒灰岩,储集空间以铸模孔、粒内溶孔和晶间溶孔为主。飞三段整体是致密的,但储层段仍有较高的孔隙度,由于裂缝的存在从而提高了储层段岩石的渗透率。由测井曲线特征分析可知,鲡粒灰岩储层具有相对低的自然伽马、低密度、低速度和相对高的电阻率。储层的发育主要受控于沉积作用、成岩作用及破裂作用等因素。通南巴飞三段储层分为四类,河坝1井飞三段储层属于Ⅰ类和Ⅱ类储层。By using the data of logging curves,cores,the litho-thin sections,the reservoir characteristics and the major control factors influencing its growth of the third member of Feixianguan Formation of Tongnanba Structure in Sichuan Basin were studied.The lithologic character of Ef3 was oosparite.The reservoir space was intragranular pore,moldic pore and intercrystal pore.The third member of Feixianguan Formation was dense,but the reservoir segment was still relatively high porosity,due to the presence of cracks the permeability of reservoir rocks increased.By using logging curve analysis,it is indicated that the reservoir is relatively low natural gamma,small density,low-speed and relatively high resistivity.The key affecting factor of the reservoir is deposition,diagenesis and tectonic action.The Ef3 reservoirs are divided into 4 types,TypeⅠ and Ⅱ are high quality reservoirs.
