摘要
西江主涯发育上、下两个构造层，下构造层的恩平组和文昌组是烃源岩发育层段，其中存在的泥底辟构造是下构造层存在大量塑性泥岩的有力证据。通过油－岩对比与成熟度等分析，证明西江主洼具有生油潜力。
The sediments in Xijiang main sag can be divided into upper and lower tectonic layers, in whick the lower one develops source rock of Wenchang and Enping formations.The existence of diapirs implies a large volume mudstone in lower tectonic layer of Xijiang main sag. Xijiang main sag is proved to contain the potential source rock by petroleum-source rock correlation and mature analysis.
