| 摘 要： | 作者对环县地区长8油层组进行了详细的物源、沉积微相、砂体展布、物性、储层评价及今构造分析，在此基础上，研究了长8油层组的油气圈闭类型及油气富集规律，认为油气圈闭类型主要为岩性圈闭和构造-岩性圈闭，水下分流河道为油气富集的有利相带。油气富集程度具体受砂厚、孔隙度、渗透率等参数的控制，根据砂厚、孔隙度、渗透率等参数，参考已有的试油数据，将长8油层组的有利区块分为3类，进而对长8油层组优选出3个一类有利区块、2个二类有利区块和2个三类有利区块。

| Abstract: | Based on a detailed analysis on source analysis,sedimentary microfacies,sand body distribution,physical attributes,reservoir and tectonic structure,this paper studies oil & gas traps and hydrocarbon accumulation of Chang-8 formation,indicating that the oil-gas traps are lithologic and structural-lithologic traps,and underwater distibutary channel is the favorable facies.Hydrocarbon accumulation degree is constrained by sand thickness,porosity,infiltration rate,by which can classify Chang-8 formation into three categories in favorable blocks,with three Category I,two Category II and two Category III blocks selected. |
