摘　　要：孔古 3井的古生界烃源岩自形成以来经历了复杂的构造 -埋藏史 ,并发生多次生烃演化。基于详细的构造-埋藏史研究 ,并结合磷灰石裂变径迹测试及矿物包裹体分析 ,运用 EASY% Ro 数值模拟技术 ,深入研究了孔古 3井的古生界烃源岩的生烃演化历史 ,阐明了孔古 3井古生界生烃作用发生的构造期次、生烃强度 ,揭示了孔古 3井处古生界烃源岩曾发生过两次重要的生烃作用过程 ,分别发生在海西 -印支期和喜山晚期 ,而主要生烃作用发生在喜山晚期 ,并提出了孔店构造带是有望实现黄骅坳陷深层古生界找油突破的有利地区。After the Paleozoic source rocks formed,it has been undergone a complicated tect onic-burial history in the Konggu-3 well,and has taken place many hydrocarbon -generation evolution.On detailed research of tectonic-burial history,combine d with the apatife fission tracks testing and fluid inclusion analyses,and using the EASY%R_o numerical simulation,the paper reveals the evolution process,the tectonic episodes and the strength of hydrocarbon-generation of Pal eozoic source rocks.It comes to a conclusion that two times hydrocarbon-generat ion processes had taken place since the early Paleozoic formation,and makes an i mportant conclusion that the more hydrocarbon-generation of Paleozoic source ro cks took place in late Cenozoic.Finally,the paper brings forward that the Kongd ian structural belt is an advantage zone for the deep exploration of Paleozoic o il & gas in the Huanghua Depression.
