摘　　要：页岩气属于人工改造型气藏,地质、工程和工艺因素会影响其测试产量。利用涪陵页岩气田海量数据样本,采用灰色关联度分析方法,分析不同的地质因素对水平井测试产量的影响。研究表明,影响涪陵页岩气田水平井测试产量的地质因素包括页岩品质、物性、含气性和地层压力等,其表征分别是有机碳含量、密度、电阻率和压力系数,其中压力系数是主控因素;地质因素之间不是孤立的,而是密切相关、互相耦合的整体。Shale gas is a kind of artificial reformed gas reservoir.Geological,engineering and technological factors can affect the test production of shale gas.Based on the massive data samples of Fuling shale gas field,the influence of different geological factors on the test production of horizontal wells is analyzed with grey correlation analysis method.The research show that the geological factors related to the test production of horizontal wells in Fuling shale gas field include shale quality,physical property,gas bearing property and formation pressure,which are characterized by organic carbon content,density,resistivity and pressure coefficient,among which the pressure coefficient is the main control factor.Geological factors are not isolated,but closely related and coupled as a whole.
