摘要

Huabei area suffered a sedimentary interruption of about 130 million years during Late Ordovician to Devonian period。 Therefore， whether the Early Palaeozoic carbonate rocks with a stable distribution and a large thickness can secondarily generate hydrocarbon and form primary oil and gas pool is an important issue regarding the prospecting for primary oil and gas pools in the Lower Palaeozoic formations。 Well Konggu 3， located in the northwestern Kongdian anticlinal structural belt， produced oil from the primary Ordovician limestone oil pool reserved in the Ordovician Fengfeng Formation。 The crude oil characteristics and oil-source correlation show that oil source rock are Ordovician limestone。 So it is a primary oil pool with source and reservoir rocks in the same formation。 The studies on the secondary hydrocarbon generation of source rocks and the primary oil of Well Konggu 3 have a great significance to firmly prospect for Lower Palaeozoic primary oil and gas pools in Huabei area。
