大港滩海地区沙一段下部储层中方解石脉的成因
摘要
Abstract
The genesis of the calcite vein in the studied reservoir is discussed based on the analysis of carbon and oxygen isotope composition data of 12 calcite vein samples and geological background in Dagang beach area. The result shows that the calcite resource in the area exists in two different environments. There is a close relationship between the isotope composition of the calcite vein in mic-ritic limestone or calcareous sandstone in the studied area and that in continental sedimentary carbonate in Bohai Bay area,which shows that there is definite relation between their sources,or the calcite vein in two areas is all from sedimentary carbonate. The carbon in the calcite vein in fine sandstone or calcareous sandstone is not directly from the continental sedimentary carbonate at least,and the forma' tion of the calcite vein is related to the activity of thermal fluid.关键词
