摘　　要：依托昌页参1井现场解析实验数据及气测录井数据,探讨了页岩开采量与钻探工艺参数的相关性,页岩气钻探工艺参数主要包括钻压、钻时及钻井液性能指标。研究表明:页岩开采量与钻压呈中等正相关;页岩开采量与钻时呈弱正相关;钻井液性能指标中,页岩开采量与钻井液密度呈弱正相关,页岩开采量与钻井液温度和电导率均无相关关系;钻压、钻时和钻井液密度是影响页岩开采量的主控因素,故在勘探中可适当增加上述参数,以提高页岩开采量。In order to discuss the relationship between the indices of drilling process and shale gas content,the data of the scene analytical experiment and gas logging of Canyi well in Changye have been studied in this paper.The indicators of drilling technology of shale gas mainly include drilling pressure,drilling time and the indicators of drilling fluid properties.The result indicates that the relationship between drilling pressure and shale gas content is moderately positive;the relationship between drilling time and shale gas content is lowly positive;in the indicators of drilling fluid properties,the relationship between density and shale gas content is lowly positive;the shale gas content is not related with temperature and conductivity.Drilling pressure,drilling time and density of drilling fluid are main factors on impact of shale gas content,so we can improve the shale gas content by increasing these indicators in shale gas exploration.
