准噶尔盆地侏罗纪含煤地层沉积有机相研究

准噶尔盆地侏罗纪煤系是一套良好的生油源岩，其生油潜力取决于沉积有机相。笔者依据有机岩石学研究方法，利用显微组分的多种特性，将侏罗纪沉积期划分成高位沼泽、森林沼泽、流水沼泽和开阔水体４种沉积有机相类型，其中森林沼泽有机相和流水沼泽有机相是主要的生烃有机相，森林沼泽有机相是煤成气的主要源区，流水沼泽有机相则是煤成油的主要源区。

THE STUDY ON SEDIMENTARY ORGANIC FACIES OF JURASSIC SERIES IN JUNGGAR BASIN

Jurassic coal measures in Junggar basin are better oil source rocks. The hydrocarbon generation potentical depends on sedimentary organic factes. Because of the characteristics, type and abundance of macerals in source rock and vitrinite reflectance can show oil and gasgenerating conditions and sedimentary environment, so the sedimentary organic factes can be divided based on the maceral dual nature, organic petrology and organic geochemistry. In this paper,Jurassic coal measures are divided into four sedimentary organic factes by means of above method, i. e. high moor organic factes, forest swamp organic factes, running water factes and open water factes, of which forest swamp and running water swamp organic factes are the best hydrocarbon generation organic factes.
