| 摘 要： | 焉耆盆地是中国西部众多中新生代小型含煤盆地之一。自 1993年开始进行风险勘探以来 ,钻探目标主要是背斜圈闭 ,主要油气藏类型均为背斜或断背斜型。目前盆地的勘探程度仍较低 ,剩余资源量主要赋存于非背斜圈闭中。随着勘探程度的加深 ,非背斜油气藏将在油田勘探中占据越来越重要的地位。对该盆地非背斜圈闭形成的地质条件进行了系统分析 ,并讨论了盆地内可能存在的非背斜油气藏的成因分类 ,初步预测出本区发育 4大类 11种非背斜圈闭油气藏 ,并讨论了不同类型非背斜圈闭的发育演化史 ,指出了盆地非背斜油气藏的勘探方向。

| Abstract: | Yanqi basin is a coal bearing basin in west China. Since 1993, the drilling targets of this basin have been focused on anticline traps all along. The exploration maturity of this basin is still lower at present, and the petroleum volume mainly remains in the none anticline traps. In this text, the geological factors and the origin of the non anticline traps are discussed in detail. It is considered that four types of non anticline reserviors were developed in Yanqi basin and can be subdivided into 11 subtypes. The evolution histories of each type of non anticline traps are discussed. The exploration directions of the basin are pointed out. |
