Identification technology of coalbed methane horizontal well while drilling based on multi-information integration

According to the lhit and shorage of a single data source applied to the measurement and identifcation of thecoalbed methane horizontal well while drilng the paper provided that he measurement and dentification tfchnology was the key to ealize the geological seeing during the drlling construction process of thecoalbed methane horizontal ell and was the power suport of the drlin bt to be succssilly expanded in the target stata.with a ful iliration on the advantages ofthe muiti-nformation integration technology to pro.ess difrent information sources.based on theBP neural network as the inte ration agrfthm,the comprehensive lo:ging data and the elements measuring technology while drling were inegrated.The element measuring instrument whileadrling matc hed to the mut-information integation technology was optimized.An onine plan of the measuring instruction whiedriling was designed a technical prcedure torealize the identificatin funcion whie&rilling was determined and an identification networs of the maulit-information integration was establis ed.An acual appication of the identfration netwvork whie diling o a well in Qinshui Basin based on the multi-information integration showed that the accurate identfication results were accurately obtained.
