摘　　要：为了实现长水平段页岩气井有效穿越优质"甜点"段,基于工区内首口页岩气参数井录井、测井及岩心资料分析,找出了目的层段内的"甜点"段、优质"甜点"段及最优"甜点"段,给出了"甜点"段、"甜点"段上方的标志层及进入标志层的随钻录井和自然伽马曲线变化特征,形成了标志层确定方法。应用试验16口井,成功率100%,优质"甜点"段钻遇率98.5%,应用效果良好。In order to realize the long horizontal effectively through quality ＂ dessert＂ section in shale gas well,based on analyzing data of logging,mud longing and core in the first export of shale gas parameter well,the ＂ dessert＂ section in target layer,high-quality ＂ dessert＂ section and the optimal ＂ dessert＂ section and giving the ＂ dessert＂ section,marker layer upside on ＂ dessert＂ and the curve variation characteristics while the bit enter the mark layer logging were find out.Finally a mark layer determination method was formed.At present,16 wells has been tested,the success rate is 100%.The high-quality ＂ dessert＂ section drilling rate is 98.5%,the application effect is excellent.
