| 摘 要： | 对大港滩海地区沙一段下部储层中方解石脉的12个碳、氧同位素数据进行了分析,并结合工作区地质背景,探讨了该区方解石脉的成因问题.结果表明:大港滩海地区沙一段下部储层中方解石脉存在于2种不同的环境当中.泥晶灰岩或灰质砂岩中的方解石脉的同位素组成与渤海湾地区陆相沉积碳酸盐具有强烈的渊源关系,即方解石脉的物质组成来自沉积碳酸盐;细砂岩或钙质砂岩中的方解石脉的碳至少不是直接来自于陆相沉积的碳酸盐岩,该种方解石脉的形成与热流体活动有关.

| 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 micritic limestone or calcareous sandstone in the studied area and that in continental sedimentary carbonate in Bohai Bay a... |
