摘　　要：海拉尔盆地苏德尔特构造带凝灰质特殊储层表现为强成岩作用下特殊蚀变矿物的混杂共生组合特征,该文重点对其特殊储层成岩蚀变与物性控制进行了分析研究。该区成岩作用的特殊性在于:还原、pH碱性条件、富Fe2+以及富碱金属钠元素的流体环境下的火山凝灰岩以及含火山凝灰质的砂泥岩成岩蚀变,受构造和断裂影响明显,柯绿泥石、钠板石、钠长石化、菱铁矿等混杂共生组合对成岩物性具有很大的控制作用。The special tuff reservoir in Sudeert Structural Belt of Hailaer Basin is featured by the mixed association of special alteration minerals under the effect of strong diagnesis. The diagenetic alteration of the special reservoir and physical controlling of this region are studied in this paper. The diagenetic particularity of this region is listed following： the diagenetic alteration of volcanic tuffaceous sand shale and volcanic tuff, under the fluids environment of reduction, basic pH, and abundance of Fe^2＋ and sodium, has been obviously affected by structures and faults. The mixed paragenetic association of corrensite, allevardite, albitization, siderite and other minerals has strong controlling effect on the diagenetic properties.
