川东鄂西某页岩气井录测井解释评价研究

页岩气储集层的勘探开发最早始于美国，目前已成为国内非常规气藏勘探开发的重点和热点。2010年来，江汉油田分公司在川东鄂西石柱复向斜某构造钻探了中国石化集团的首口页岩气探井，解释评价研究人员应用气测录井、X射线荧光录井（XRF）等录井方法，结合交叉偶极子声波测井、微电阻率成像测井（FMS）等测井方法，利用多种录、测井解释评价图板，在侏罗系下统自流井组东岳庙段解释了2层总厚度为50m的页岩气储集层，其中井段598.0～646．0m页岩气储集层经射孔及压裂作业，喜获工业气流。通过该井的解释评价，形成了有效的页岩气储集层的解释评价方法和初步判别标准，对国内页岩气储集层的勘探开发具有一定的指导作用。

The study for the interpretation and evaluation of mud logging and well logging for a shale gas well in Eastern Sichuan-Western Hubei area

The exploration and development of shale gas reservoir first started in the United States.At present,it has become the focus and the hot spot of domestic unconventional gas exploration and development.At the end of 2010,Jianghan Oilfield Company drilled a shale gas exploration well in a pillar synclinorium structure of Eastern Sichuan-Western Hubei area,which is the first shale gas exploration well for Sinopec Group.By using gas logging and X-ray fluorescence(XRF) logging methods,combining with cross-dipole Sonic logging,micro-resistivity imaging logging(FMS) method and using a variety of mud logging and well logging interpretation and evaluation charts,the researchers interpreted 2 layers of total thickness 50m shale gas reservoir in artesian well group,Dongyuemiao interval,the Jurassic.The well interval 598.0 ~ 646.0m shale gas reservoir awarded the industrial gas flow through the perforation and fracturing operations.By the interpretation and evaluation of the well,the effective interpretation and evaluation methods and preliminary criterion for shale gas reservoir were formed,which would play a guiding role in the exploration and development for domestic shale gas reservoir.
