摘要：方正断陷东部国陷发育两套烃源岩，底部烃源岩为深灰色泥岩夹薄层煤的煤系地层，顶部经源岩为半深湖一深潮相的深灰色泥岩，西部凹陷仅发育底部烃源岩，为煤系泥岩。以测井烃源岩评价为基础，采用地霞相法在平面上追踪和预测了新安村+乌云组烃源岩的分布范围及厚度。烃源岩测井模拟和地震预测表明：底部有效烃源岩厚度较大，普遍大于40m，东西凹陷带都有分布；顶部有效烃源岩厚度为30-60m，主要分布在东部凹陷带的大林子次凹和德善屯次凹。有效烃源岩的分布规律和油气来源研究为油气勘操和石油地质综合研究提供了依据。

Abstract: Two sets of the hydrocarbon source rock are developed in East Sag of Fangzheng Fault Depression: the bottom is the coal-measure strata of the dark gray mudstone commingled with the thin coal seam; the top is the dark gray mudstone with the semi-deep-deep lake facies, while only the hydrocarbon source rock is developed in West Sag, it is the coal-bearing series. On the basis of the evaluation of the hydrocarbon source rocks, with the help of the seismic facies method, the distribution range and thickness of Xin'an Village + Wuyun Formation hydrocarbon source rocks were tracked and predicted on the plane. The well logging modeling and seismic survey showed that the effective hydrocarbon source rocks are pretty thicker: commonly more than 40 m, and moreover distributed in both East and West Sag; the thickness of the top ones is between 30 m to 60 m, mainly distributed in Dalinzi Subsag and Deshantun of the eastem sag belt. The researches on the distribution laws of the effective hydrocarbon source rocks and petroleum sources have provided a certain evidences for the petroleum exploration and geological comprehensive study.
