摘　　要：探讨鄂尔多斯盆地苏里格地区下古生界储层及气藏控制因素与成藏规律。通过对气田已有的奥陶系钻井资料、测井资料、试气资料以及生产动态资料的综合分析,结合储层特征、顶面构造、沉积相与成岩作用等方面研究,总结归纳出奥陶系马家沟组天然气成藏规律,认为苏里格地区下古生界气藏勘探开发应首先考虑古残丘-古沟槽(洼地)之间的过渡地带,部署井位时应该重点考虑马五14和马五31小层,同时考虑选择鼻翼和鼻隆部位的喀斯特作用强烈发育地带。According to the analysis of the drilling,logging,gas test and productive data,the authors discuss the control factors of the gas reservoir of Paleozoic group.Combined with the reservoir characteristics,superface structures,sedimentary facies and diagenesis,etc.,this paper concludes the accumulation regularity of natural gas pools in Ordovician Majiagou Formation（O1m） of the Sulige area in Ordos basin and an advantageous direction of gas exploration of Ordovician is obtained.During the gas exploration in Paleozoic group,the authors think that the next two points should be considered.Firstly,people should pay attention to the areas between the paleo-hammock and the ancient groove（depression）,and the well locations should be in O1m54-1 and O1m51-3.Secondly,the strong karst actions in the nose alar-like and nose uplift-like areas also should be taken into consideration.
