摘　　要：安深1井是一口以寻找页岩气为主要目的的风险探井,本井钻探结果证实本区页岩发育、页岩层段气测异常明显,录井资料、实验室分析化验资料、现代测井技术解释均证实本井页岩孔隙度、粉砂质含量、有机质类型、丰度均与美国富气页岩具有相似的特征;现代测井技术的计算数据表明本井页岩层中赋存着丰富的吸附气、游离气。运用C1/ΣC-C2/C3气测解释图版、皮克斯勒气测图版、气测曲线"幅差形态法"对安深1井页岩层段进行解释,经地层压裂试油证实,这些解释评价结果是可信的。Anshen 1well is adventurous prospecting well which seeks for shale rock gas.Well drilling confirmed shale rock developed in the study area,shale rock layer gas logging indicates abnormally.Mud logging data,analytical lab data,modern logging interpretation all confirmed the porosity,the powder sand content,organic matter type and abundance of this shale rock all are similar to America gas-rich shale rock.Calculation data of modern logging technology indicates rich absorption gas and free gas exist in the shale rock.In this article,the well development degree,shale rock layer gas logging abnormal indication have been introduced firstly,then the evaluation basis of shale(mud) rock hydrocarbon by using gas logging has been elaborated.Based on this,the interpretation of Anshen 1 well shale rock layer by applying C1/ΣC-C2/C3 gas logging interpretation chart version,Picxler gas logging chart,gas logging curve have been introduced.Confirmed by formation fracturing oil testing,these interpretation evaluation results are credible.
