页岩油气勘探中的录井技术选择

The Logging Technology Selection in Shale Oil-Gas Exploration

介绍了美国富气页岩的主要特点,对常规地质、气测、地化、定量荧光、核磁共振、XRF元素录井等相关录井技术在泥页岩油气选区(选层)评价、泥页岩层流体性质解释评价中的录井技术作用进行了细致的分析。结合AS1井应用实例,认为目前录井技术基本上能够满足页岩油气勘探评价需要。同时,依据现有录井技术能力,还对页岩含气量测试、天然气组分稳定碳同位素分析、核磁共振分析等问题提出了相应的建议。

The article introduces the main characteristics of USA gas-rich shale and gives a detailed analysis of the effect of the relevant logging technologies such as conventional geological log,gas logging,geochemical log,quantitative fluorescent log,nuclear magnetic resonance log,XRF element log upon shale oil-gas selected block(selected bed) evaluation and shale bed fluid property explanation and evaluation.Combining with the application example of AS1 well,it considers that current logging technology can basically meet the needs of shale oil-gas exploration evaluation.At the same time,in the light of present existing logging technological ability,it puts forward relevant suggestions being aimed at the problems in the aspects such as shale gas content measurement,natural gas constituent stable carbon isotope analysis,nuclear magnetic resonance analysis.
