摘要
地球物理测井可以直接服务于全球变化的方面有:地球物理测井矿物分析(粘土矿物分析计算、碳酸盐含量分析计算、反射光谱计算分析)、地球物理测井岩性分析(粗细成分含量分析计算、平均粒度、层里—纹理类型、岩石孔隙度、渗透率)、磁性地层测井分析(磁测试对比或计算后为全球变化问题间接服务的有:同位素地层分析、旋回与层序地层划分、地层水化学成分分析;在以DSDP/ODP(深海钻探/大洋钻探),ELDP(欧洲湖泊钻探计划),以及大陆钻探计划中,全球变化是其最基本的科学目标.地球物理测井也是必测的录井项目.另外,地球物理测井与层序地层学相接合。
Well log could be directly used in Global change analysis in the following:Minerals analysis (clay contents,supply,refection spectra analysis of rocks),Lithology analysis (coarse and fine contents,average coarseness,layers and laminas,porosity and permeability),magnetic stratigraphy (susceptibility and plaeomagnetics),microbiology (their activity and diversity) etc. It could serve for global change research by correlating with other methods of isotopic stratigraphy,(cycle) sequence stratigraphy,rock water analysis etc. The global change is one of the main scientific goals in DSDP/ODP,ELDP,CDP and well logging had been the basic measurements in these projects. Another important fields of well logging in global change is the study of raising Tibet by the DSDP/ODP geophysical logging or surrounded basins.
