摘要
Abstract
Based on the research results of deep coalbed methane exploration in China,and the analysis data of drilling,seismic and coal core experiments in the Xung-Yi exploration area in the southern Ordos Ba-sin,the key factors of deep Carboniferous Taiyuan Formation,such as coal seam distribution,coal rock and coal quality,reservoir conditions,preservation conditions and gas bearing properties are analyzed,and then the reservoir-forming conditions and exploration potential of coalbed methane in Taiyuan Formation are evaluated.The results show that the coal seam of Taiyuan Formation in the Xen-Yi exploration area has the advantages of large thickness,stable transverse distribution,high coal rank,medium ash content and good gas bearing.The coal bed methane resources of Taiyuan Formation are 1 754×108 m3,which has a good exploration potential.The coal seam is developed in the middle and eastern part of the Xun-Yi exploration area,with high gas content,undeveloped faults and relatively shallow buried depth,which is a favorable ar-ea for coalbed methane exploration.On the basis of the selection of favorable areas,the review of old coal-bed methane wells has been carried out,and the PZ2 well has been selected to carry out the gas test of Taiyuan Formation coal seam by fracturing,which has a good reference for further exploration in this area.关键词
