Abstract
In order to further improve the development effect of coalbed methane wells,a variety of seismic attributes of the target coal seam are extracted,and production distribution samples of developed wells are established.On this basis,through the fitting analysis of all seismic attributes and yield samples,the index weight method is used to calculate that the cumulative contribution rate of coherence and root mean square amplitude to yield is more than 85%,so the two seismic attributes of coherence and root mean square amplitude are selected.Finally,through the fitting correlation coefficient between the two attributes and the yield,the compre-hensive attribute prediction formula was established,and the favorable development units were divided.The correlation between forecast results and developed well production is enhanced.The results show that development units can be accurately divided through well data and seismic attribute optimization technology.关键词
