测井技术的应用及其在科学钻探研究中的意义

测井技术是从上世纪20年代发展起来,60年代渐趋成熟,现已被广泛应用于油田、煤田等地质勘探工作中.上世纪开始的DSDP(深海钻探)、ODP(大洋钻探)I、CDP(国际大陆科学钻探计划)、KTB(德国的大陆科学钻探计划)等项目采用测井曲线研究古环境、古气候,确定地层性质等方面取得了进展,极大的拓展了地球物理测井在地质上的应用范围,使测井技术由油气、煤炭测井的地层分析上升到测井地质的成因研究,也渗透到提取古气候信息的领域上.我们在柴达木盆地盐湖科学钻探工程中也采用了测井技术,旨在通过与岩芯多指标对比分析,探索应用其指示意义测井技术在石油、盐类资源普查及古环境研究中.

Application of the welllogging technology and the significance in the scientific drilling

Well logging technology had developed in the 1920s,and grew up in the 1960s.It is now widely applied to the geological reconnaissance of the oil field and coalfield etc.This technology has been adopted by the ODP,ICDP,DSDP and KTB,and has taken a development in studying the paleoenvironment and paleoclimate,ascertaining the property of the stratum and so on,which has greatly extended the geologic application area of physical geography well logging,which has made well logging technology rise from the stratum analysis of oil and coal well logging to the study for the cause of well logging geological formation,which also has infiltrated into the field of distilling paleoenvironment and paleoclimate information.We also use the well logging technology in the Chaidamu basin saltlake drilling project,we will draw a comparison between the well logging curve and the index of rock cores,expecting to find the significance of the well logging technology in searching resource and paleoenvironment study.
