摘要： 应用影响因素校正及趋势拟合分析方法，对库车坳陷米斯布拉克地区地球化学背景及化探异常分布特征进行了研究。结果表明，研究区黒英1井—米斯布拉克—卡路康下一线、沙拉依塔木—黑英山乡一线及满族塔木附近化探指标值较高，也是化探异常主要分布区。根据单指标异常级别、组合及配置关系，识别出16个综合异常。根据综合异常所处的构造位置、分布特征及其组合关系，又划分出了5个有利—最有利和有远景的综合异常区，其中，中部环状综合异常区为最有利油气勘探区。

Abstract: By means of influence factors correction and trend fitting analysis methods, this paper studied the characteristics of geochemical background and geochemical anomaly distribution in Meath Braque area in Kuqa depression of Tarim basin. The results show that lines along Heiying?1well?Meath Braque?Carlo Kangxia, Sarah Hitam?Heiyingshan, and near Manchu Tamu have high value of geochemical explorative index, also they are the main distribution areas of geochemical anomaly. According to the anomaly level, combination and configuration relationship of the single geochemical index, it was divided into sixteen comprehensive anomalies. Based on the structural position, distribution and combination relationships of these geochemical anomalies, this area was divided into five comprehensive anomalies regions, among which there are only one most favorable area and two favorable areas. Integrated with the oil and gas geologic conditions in this area, it is suggested that the central annular anomaly zone could be the most favorable area for further petroleum exploration
