摘要:

岩石薄片鉴定、X射线衍射分析和红外光谱分析表明,东营凹陷郑家、王庄地区沙河街组碎屑岩储层中粘土矿物的主要类型为伊利石/蒙皂石无序间层矿物和高岭石,以及少量的伊利石和微量的绿泥石矿物。伊利石/蒙皂石无序间层矿物可进一步分为钙型、钠型和钠—钙过渡型3类,其中对储层伤害最大的为钠型。高岭石矿物以结晶度高者居多,初步分析其为自生成因。结晶度差者为陆源成因或长石蚀变成因。自生高岭石的存在大大改善了储层的物性。

Abstract:

Clay minerals consist mainly of kaolinite and randomly interstratified illite/montmorillonites(S/I) in the clastic reservoir in Shahejie Formation in the Zhengjia-Wangzhuang area in DongYing sag according to thin section, X-ray diffraction, infrared ray spectrum analyses. Still, illite and chlorite exist in a small amount. The results of the study show that S/I can the subdivided into three kinds: calcium type, natrium type and their mixture type, of which the natrium one has the worst influence on reservoirIn this area, the high crystallinity kaolinite is the most, and its most possible origin is authigenic. The low crystallinity kaolinite is allogenic or from feldspar's alteration. And authigenic kaolinite can improve the reservoir physics effectively.

Key words: randomly interstratified illite/montmorillonites, kaolinite, clastic reservoir, formation damage
