—、序言 江汉平原位于湖北省中南部和湖南省北部,包括云梦泽、江汉冲积平原及洞庭湖平原等地面积约6万平方公里。 这个地区经前人研究无论是从构造观点或是沉积观点来看,都是有希望含油的地区。加上平原外围及内部已发现了十数起油气苗,因此更有必要布置勘探工作。但是,该区大地构造复杂,平原区又几乎全为第四纪沉积所复盖,因此究竟有无希望储油,首先应借助于物探工作加以探明。
-, Preface Jianghan Plain is located in central and southern Hubei Province and northern Hunan Province, including Yunmengze, Jianghan alluvial plain and Dongting Lake plain covers an area of about 60,000 square kilometers. This area has been a promising oil-rich area by its predecessors, both from a tectonic point of view and from a sedimentary point of view. Together with the discovery of dozens of oil and gas spheres in the outer and inner parts of the plain, exploration work is even more necessary. However, due to the complex structure of the earth and the almost complete deposition of the Quaternary sediments in the plain area, whether or not oil is hopelessly stored should first be proved by means of geophysical prospecting.
