句容地区是我国南方中、古生界油气勘探较早发现工业油流的地区之一。句容中、古生界油气勘探相继在白垩系、三叠系和二叠系发现大量不同级别的油气显示,取得了一定的勘探开发成果,但是仍然存在着油气分散、富集性较差等问题。研究认为,该区二叠系泥岩分布面广、质地较纯,有望成为上古生界内幕型圈闭的有效盖层。

Jurong area is one of the areas with earlier commercial oil flows in the Mesozoic-Paleozoic in South China. Different levels of oil-gas discovery have been made in the Cretaceous, Triassic and Permian through oil and gas exploration in Mesozoic-Paleozoic in Jurong area,and good exploration and development results have been obtained. However, problems still exist, such as oil-gas dispersion and poor enrichment. The study concluded that the Permian mudstones distribute widely in this area and the quality is pure, being expected to be the effective seais for the traps within the Upper Paleozoic.
