摘要
依据山东济宁何岗煤田自然伽马、人工伽马、视电阻率及声波时差等测井参数的响应特征及规律性,对该区新补勘的9个孔进行了测井资料分析与综合对比,并通过划分标志层及补充勘探6号孔与9号孔的层位对比,有效排除了局部沉积环境变化对地层划分的干扰,确认补充勘探6号孔位于断层上,段层落差约为59.82m。该测井解释结果与地质资料基本吻合。
Based on response characteristics and regularity of log parameters of gamma-ray,gamma-gamma,apparent resistivity and sonic differential time in the Hegang coalfield,Shandong,analyzed and comprehensively correlated 9 boreholes in supplementary exploration in the area.Through index bed defining and Nos.6 and 9 boreholes＇ strata correlation,effectively eliminated strata division interference from topical sedimentary environment changes.Confirmed No.6 borehole is located on a fault with throw 59.82m.The logging interpreted results are basically tally with geological information.
