本文从区域古地温演化的角度出发,探讨了华北盆地北部下古生界的含油远景。分析的基础主要建立在作者编制的古地温演化图之上。制图的方法引用了电子计算机;利用等值线扫描数字化处理基础图件,编成下古生界古地温演化图。根据古地温演化的特点,并考虑其它与油气有关的地质因素,作者对下古生界五套生储盖组合分别进行评价;同时指出在华北盆地北部寻找下古生界原生油气藏的有利地区。
Based on the regional paleogeothermal evolution, this paper discusses the oil prospects of the Lower Paleozoic in northern North China Basin. The basis of the analysis is mainly based on the ancient geothermal evolution map compiled by the author. Drawing method refers to the electronic computer; using contour scan digitization of basic map, compiled into the paleo-Paleozoic paleo-geothermal evolution map. Based on the characteristics of palaeogeothermal evolution and other geological factors related to oil and gas, the authors evaluated the five sets of reservoir-cap assemblages in the Lower Paleozoic, respectively, and pointed out that the favorable areas of the Lower Paleozoic in the northern Huabei Basin .
