在煤田地质勘探中,测井资料作为钻探资料的补充和验证,已成为煤田地质勘探必不可少的重要手段。较之数字测井以前,伪造测井资料几乎是不可能的,因此,测井曲线是鉴别地质资料可靠程度的重要依据。但目前流行的部分数字测井系统存在着严重缺陷,伪造测井曲线易如反掌,致使极少数煤田地质勘查队伍出现伪造测井曲线的现象,导致煤田地质勘查资料严重失实。伪造测井曲线的主要技术手段是依靠软件对部分测井数据进行复制,伪造的测进曲线有三种特征:重复性、矛盾性和不协调性,该特征是识别伪造曲线的主要标志。在实际工作中,可先查看测井记录是否为明码记录,然后再依据伪造测井曲线特征对测井资料进行识别,必要时可索取原始测井记录曲线予以核对。
In coalfield geological exploration, logging data as a supplement and verification of drilling data has become an indispensable means of coalfield geological exploration. Forging log data is almost impossible before digital logging. Therefore, logging data is an important basis for identifying the reliability of geologic data. However, there are serious flaws in some popular digital logging systems. Forging logging curves is easy, leading to the phenomenon of fake logging curves in a few coalfield geological prospecting teams. As a result, the geological prospecting data in coalfields are seriously inaccurate. The main technical means of forging logging curves is to copy part of logging data by software. There are three characteristics of counterfeit testing curves: repeatability, contradiction and incongruity, which is the main symbol of identifying counterfeit curves. In practice, you can check whether logging records are plain records and then identify logging data according to the characteristics of forged logging curves. If necessary, obtain the original logging records for verification.
