ABSTRACT: The Dongdao Haizi Depression is one of the important oil and hydrocarbon producing depressions in the Junggar basin and the Permian formations are the main hydrocarbon source rocks and the main hydrocarbon producing formations in the Dongdao Haizi Depression. In this paper, through the determination of the TOC and the S1 + S2 of the hydrocarbon source rocks of the lower Urho formation of the Permian, we judge that this hydrocarbon source rock belongs to the better oil-generating category, and through the determination of the microscopic composition of the casein, we find that the organic matter of this source rock is mainly of type II1, and a few of them are of type II2; all of them have reached the mature-high mature stage. The organic matter of the hydrocarbon source rocks was found to be mainly of type II1, with a small part of type II2; the hydrocarbon source rocks of the lower Urho formation have all reached the mature-highly mature stage.
