鄂尔多斯盆地志丹探区延长组储层特征研究及评价

Reservoirs Characteristics and Evaluation of Yanchang Formation in Zhidan Area, Ordos Basin

  • 摘要: 在大量岩心铸体薄片及物性等资料统计分析的基础上,对志丹探区延长组储层的沉积学、岩石学、物性等特征及孔隙类型和孔隙结构等进行了深入研究,并对储层进行了分类评价。研究结果表明,研究区延长组储集层具有成分成熟度低、结构成熟度高的特点;孔隙类型主要为粒间孔、溶蚀孔等类型,属于中孔、低渗型和中低孔、特低渗型储层。综合多参数评价,研究区延长组中长2和长6油层组分别发育类和类储层,个别地区发育类和类储层。
    Abstract: In this paper,we analyze the data of drilling cores and cast thin sections,study the petrologic characteristics,characteristics of pore and permeability,and the porosity types,and discuss the effect of such factors on oil-bearing layers of Chang-2,Chang-3,Chang-4+5,and Chang-6 in ZHidan area. The resultindicates that the Yanchang reservoir is characterized by low mineral maturity and highst ructure maturity,of which Chang-2,Chang-3,and Chang-4+5 are better than Chang-6 in mineral maturity. The physical property shows that Chang-2 is characterized by middle-sized pores and low permeability while Chang-3,Chang-4+5,and Chang-6 are very low in permeability. Reservoirs are divided in to four types by several parameters,withChang-2 oil-bearing layer containing reservoir type and Chang-6 oil-bearing layers mostly containing reservoir type-Ⅲ.
