Research On Speed Raising Technology Of Shale Gas In PingQiao Block Silurian Formation

Fuling shale gas field is the first field that has been commercially explorated in China.In November 2013 SINOPEC designed exploration plan for fuling shale gas field.In December 2015,Fuling gas field successfully completed production target and start the second stage of exploration of the field.The second stage has areas including JiangDong,PingQiao,BaiTao,BaiMa,ZiLiChang.PingQiao block is located in ChongQing wulong,covers an area of 102.9km2.This paper is mainly aimed at PingQiao blocks in the analysis of engineering geological characteristics of PingQiao blocks and the basis of drilling data,conclude the main problem in PingQiao ZhiLiu formation is high arasiveness.Using well logging data and acoustic data,this paper analysis properties of the formation.According to the drilling bit that used in the first stage,this paper improved the structure of the KSD bit.The improved bit cooperate with the PDM speed up the exploration and development of shale gas in deep reservoir.
