摘要
相较于传统的模拟测井技术,数字测井技术在复杂地质条件下的数据采集及处理方面具有显著优势,是未来煤田测井技术发展的重要方向之一。本文以沁水煤田某生产井为研究对象,基于矿区前期的地质勘探资料,应用PSJ-2A型数字测井仪器和ClogPro V2.0数据处理软件对该井进行裸眼井测井和固井质量检查测井。首先,根据测井目的分析数字测井项目及测井解释模型;其次,结合岩、煤层定性和定厚解释原则形成测井综合解释成果;最终,测井成果显示,1#煤层厚度为6.52 m,底板深度为631.67 m,其渗透性较差、隔水性较好,具备良好的煤层气存储条件,且该生产井固井质量合格。
Compared with traditional analog logging technology,digital logging technology has significant advantages in data acquisition and processing under complex geological conditions,and is one of the important directions for the future development of coalfield logging technology.This paper takes a production well in Qinshui coalfield as the research object.Based on the previous geological exploration data from mining area,the PSJ-2A digital logging instrument and ClogPro V2.0 data processing software were used to perform open-hole logging and cementing quality inspection logging on the well.Firstly,the digital logging project and interpretation model were analyzed based on the logging purpose;Secondly,comprehensive logging interpretation results were formed by integrating qualitative and quantitative interpretation principles for rock and coal seams;Finally,the logging results indicated that the No.1 coal seam has a thickness of 6.52 meters and a floor depth of 631.67 meters,characterized by poor permeability and good water isolation,which provide favorable conditions for coalbed methane storage.Moreover,the cementing quality of the production well was found to be satisfactory.
