摘　　要：白音查干凹陷锡林好来地区腾格尔组主要发育低渗、特低渗油藏,通过研究岩心、砂岩薄片、铸体薄片、扫描电镜、储层物性等资料,对储层宏观非均质性(层内、层间、平面)进行了分析,研究表明,腾格尔组储集层整体上宏观非均质性较强。利用储层各项参数对其进行了储层综合评价,分析了其对注水开发的影响,并指出剩余油有利挖潜区。The exploration and development of the oil-gas field is affected by the reservoir heterogeneity, so it was quite necessary to study the reservoir heterogeneity and find out the rule of the influence for clarifying the distribution of the remaining oil, taking reasonable measures, enhancing recovery factor and etc. Tengger formation of Xinlinhaolai area in the Baiyinchagan sag is a low to super-low permeability reservoir, according to the core thin section, the rock thin section, scanning electron microscope, reservoir property, and so on. A in-depth research has done on Tengger formation reservoir macroscopic heterogeneity. The results show that the reservoir displays strong macroscopic heterogeneity in the interlamination. By using the parameters of the reservoir, the comprehensive evaluation and classification have been carried out. Research shows that the macroscopic heterogeneity is relatively strong in the area on the whole. At the same time, aiming at the influence of heterogeneity to waterflooding development, the favorable zone of the reservoir evaluation has been put forward.
