一、前言世界若干地区有关二叠纪非(虫莛)有孔虫(下简称有孔虫)的研究已有百余年的历史,但至今大多限于化石形态、构造及分类上的研究。近年来,海相二叠纪含油、气层的发现,其中富含的有孔虫化石越来越引起人们的注意,特别是有孔虫的生态以及迄今尚未详细研究的二叠纪各时期有孔虫组合特征,均有必要深入进行综合分析,以适应当前石油地质科学发展的需要。我国华南地区海相二叠系的分布极广,并含十分丰富的有孔虫,是研究二叠纪有孔虫
I. Preface The research on permian foraminifera (Permian foraminifera) in some areas of the world has been more than one hundred years, but most of the studies have been done on the morphology, structure and classification of fossil. In recent years, the discovery of marine Permian oil and gas reservoirs, in which the foraminifera rich in fossils have attracted more and more attention, especially the ecology of foraminifera and the Permian periods which have not been studied in detail The characteristics of the combination of boreholes, are necessary for in-depth comprehensive analysis to meet the current needs of the scientific development of petroleum geology. The distribution of marine Permian in southern China is very wide and contains abundant foraminifera. It is a study of Permian foraminifera
