基于岩心刻度的测井地质分析方法
|
摘要
怎样挖掘测井曲线隐含的巨量有用信息,一直为地质家关注,在岩心中提取地质信息,并建立它与测井曲线的刻度关系,可能是一条有效途径.但这一思路在测井技术中缺少尝试,究其原因在于,测井技术手段是以地球物理为基础.该思维方法赋予"岩心刻度"测井技术的思路是,应用数理统计的方法建立测井资料与岩心分析数据之间的关系,为孔隙度、渗透率及饱和度等参数建模提供依据.该方法有助于测井解释模型的建立,但对于复杂致密储层研究,仍存在明显不足:一是缺乏地质背景解读的测井评价技术本身就不完美;二是现代油气勘探开发目标的复杂化和隐蔽性,迫使地质家急需分析和判断的证据.本文针对上述问题,提出基于岩心刻度的测井地质分析方法,该方法以地质事件为基本单元,以连续岩心中可实证的地质事件识别为依据,以地质原理和成因关系分析为认识基础,刻度测井曲线响应,达到利用测井曲线辨认地质事件的目的.文中以风暴岩、冲刷面、不同河道识别以及水进事件等地质事件的岩心刻度测井分析为案例,介绍了本方法的具体应用.
Geologists pay attention to how to dig massive information which hidden in well logs. Extracting geological information from the drill core and building the calibration relationship with well logs maybe became an effective way.However,this idea in logging technology lack of trying. Well logging technology based on geophysics. When it study the relationship with drill core,the train of think is using the method of mathematical statistics. This approach helps the establishment of the logging interpretation model and provides basis for the parameters such as porosity,permeability and saturation modeling. However,there is insufficient when it comes to complex compact reservoir.There are two reasons. First,the well logging evaluation technology which lacks of geological background reading is imperfect. Second,the target now is more complex and private. Geologists are in badly need of evidence to analyze and judge. Based on these questions,the paper propose a logging-geology method based on core calibration. The method takes the geological events as the basic unit,puts the geological events which can be confirmed by serial cores as the gist,calibrates the response of well logging and finally achieves the purpose of using well logs to identify the geological events. The paper enumerated some cases such as tempestite,scour surface,the identifying of different river way and water-transgression events to introduce the application of the method.
