Logging technology application of Tun-1 well in Luoyang basin

With the successful experience in Ordos basin,commercial gas has been obtained from Tun-1 well by fracturing technique after completion.Through basic analysis of hydrocarbon-generating conditions,hydrocarbon resources and reservoir types,problems existing in the identification of hydrocarbon show,cracks and development degree while drilling and logging have been provided.Aiming at these problems,in combination with the geological conditions of the area,detailed analysis on the choice of conventional logging technology and hydrocarbon layers interpretation and evaluation has been carried out.
