摘　　要：随着四川盆地勘探工作向埋藏深、构造复杂区块推进,钻井现场通过采用白油基钻井液以提高钻井效率和保护环境。实践表明白油基钻井液的使用会干扰气测录井数据,影响对储集层流体性质的判断,为此深入研究分析了白油基钻井液对气测录井数据的影响,并从气测色谱仪、白油性质、井底温度和钻井条件等方面分析了白油基钻井液气测数据特征的成因,以期为油基钻井液条件下的气测录井解释提供参考依据。As the exploration in Sichuan Basin advances to blocks with deep buried and complex structures,the white oil-based drilling fluid has been used on drilling sites for drilling efficiency improvement and environmental protection.Practice has shown that the use of white oil-based drilling fluid will interfere with gas logging data and affect the identification of reservoir fluid properties.To this end,the influence of white oil-based drilling fluid on gas logging data was deeply studied and analyzed,and the origin of gas logging data characteristics of white oil-based drilling fluid was analyzed in terms of gas chromatography,white oil properties,bottom hole temperature and drilling conditions to provide reference for the gas logging interpretation under the oil-based drilling fluid.
