摘　　要：为明确有利选区目标,加深对美国油气资源现状的认识,在系统收集国内外资料基础上,以油气资源和选区评价为主线,通过地质条件综合分析、油气资源评价分析、含油气地质条件的特殊性等多方面研究,并结合勘探程度、研究区沉积相态及演化特征,对美国八个盆地区相关评价参数赋值,并根据多因素比例指定权重系数,最后对优选目标进行综合打分和排序,从而达到对研究区进行半定量—定量评价。通过资源潜力评价分析,初步认为落基山盆地区和阿拉斯加盆地区为一类盆地区;湾岸区、西德克萨斯和新墨西哥州东南部盆地区、中陆盆地区、阿巴拉契亚盆地区、东内部盆地区为二类盆地区;加利福尼亚盆地区和大西洋沿岸为三类盆地区。To optimize the favorable exploration targets and deepen understanding about the oil and gas resources conditions of America, comprehensive analysis of the geological conditions, oil and gas resource evaluation and particularity in oil and gas geo- logical conditions have been conducted on the basis of the domestic and international data. In addition, combined with the degree of exploration, sedimentary facies and evolution feature, the evaluation parameters have been taken on the eight basins of the United States, and the weighing factors have been assigned according to the proportion of multi-factor. Finally, the exploration targets are optimized and ranked, and semi-quantitative and quantitative evaluation have been finished on the study areas. Through assessment on the potential of HC resources, it is concluded preliminarily that the Rocky Mountain and Alaska are type I areas in oil and gas resources; Gulf Coast area, West Texas and southeastern part of New Mexico State basin, the Mid-Continent basin, Appalachian ba- sin region, the East basin are type Ⅱ areas in oil and gas resources, and California basin and the Atlantic coast are type Ⅲ areas in oil and gas resources.
