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.

Key words:  Chang 8 formation, favorable target, Huanxian county, Ordos basin
