摘要
通过对比分析现有研究成果,认为天山内部侏罗系和部分古生代地层是烃源岩发育的主力层位,且具有相对较好的地球化学指标,而各山间盆地之间油气地质基本条件差异大,其主要影响因素包括大地热流特征、强烈的构造变形、新生代以来的构造运动和岩浆岩分布等诸多方面。综合盆地面积、盆地内断裂情况、烃源岩层系和岩浆岩分布等因素,将各盆地划分4类不同级别,其中Ⅰ类盆地为吐哈盆地,Ⅱ类盆地包括伊宁盆地和焉耆盆地,这2类盆地具有常规油气勘探的潜力,Ⅲ类盆地包括精河盆地、小尤尔都斯盆地和大尤尔都斯盆地等,可以考虑进行非常规油气勘探,Ⅳ类盆地包括昭苏盆地、新源盆地和后峡盆地等,该类盆地可以进行各类固体矿产资源的勘探与开发。
By comparing and analyzing the existing research results, it is considered that the Jurassic and some Paleozoic strata in Tianshan are the main strata for source rocks, and have relatively good geochemical indicators, while the basic hydrocarbon geological conditions vary greatly among Intermountain basins, and the main influencing factors can be concluded as: geothermal flow characteristics, strong structural deformation Tectonic movement and magmatic rock distribution since Cenozoic. Based on the factors, such as basin area, faults in the basin, hydrocarbon source rock strata and magmatic rock distribution, the basins are classified into four categories. Among them, class Ⅰ is Turpan-Hami basin, class Ⅱ includes Yining basin and Yanqi Basin, which can have the potential of conventional hydrocarbon exploration, and class Ⅲ includes Jinghe basin, small Youerdus basin and large Youerdus basin, where the unconventional oil and gas exploration can be considered. Class Ⅳ include Zhaosu basin, Xinyuan basin and Houxia basin, which can be used for the exploration and development of various solid mineral resources.
