华北地台北部由于印支运动和燕山运动，地层抬升剥蚀，形成了多个石炭—二叠系残留盆地，其中广泛分布着上石炭统太原组海相烃源岩和奥陶系海相烃源岩。该区石炭—二叠系残留盆地可划分出４种生储盖组合：①上古生界自生自储自盖式成气组合；②下古生界自生自储、上古生界覆盖式成气组合；③古新混生古储中堵式成气组合；④气源岩与储集岩同层的煤层吸附甲烷气成气组合。从盆地边缘到中心、从凸起到深凹陷，具有从煤层甲烷—煤成油—凝析油气—干气气藏完整的气藏分布序列。该区现已发现或探明了长庆气田、苏桥凝析气田以及大城、潘庄、柳林等煤层甲烷气藏。该区石炭—二叠系残留盆地群是寻找大中型气田的有利地区，提出了鄂尔多斯、冀中东北部、冀南、沁水、黄骅、济阳、东濮等区的勘探目标与方向。
Due to the Indo-Chinese Movement and the Yanshan movement in the northern part of North China Platform, there are a number of Permo-Permian residual basins formed by uplift and denudation of the strata. Marine hydrocarbon source rocks and Ordovician marine hydrocarbon sources of the Upper Carboniferous Taiyuan Formation are widely distributed rock. There are four kinds of reservoir-cap assemblages in the Permo-Permian remnant basin: ① Upper Paleozoic self-generative self-captive gas-forming combination; ② Lower Paleozoic self-generative self-storage, Upper Paleozoic overlying gas-forming combination ; ③ paleo-old mixed paleo-reservoir blockage gas combination; ④ gas source rock and reservoir rocks in the same layer of methane adsorption methane gas into the gas combination. From the edge of the basin to the center, from the convex to the deep depression, there is a complete gas reservoir distribution sequence from the coal seam methane-coal oil-condensate gas-dry gas reservoir. The area has been discovered or proved Changqing Gas Field, Suqiao condensate gas field and the city, Panzhuang, Liulin and other coal bed methane gas reservoir. The Permo-Carboniferous residual basin group is a favorable area for finding large and medium-sized gas fields, and proposed exploration targets and directions in Erdos, northeastern Hebei, Hebei, Qinshui, Huanghua, Jiyang and Dongpu areas.
