Quick borehole data deciphering based on stratum tagging

Raw borehole data have to be deciphered to carry out auto-modeling from boreholes.To overcome the disadvantages in the existing borehole deciphering methods,such as inefficiency and fallibility,a quick borehole deciphering method based on stratum tagging is proposed.It generates and tags each geological surface of the resulted model in manner of sinking the bedding surface,and automatically assigns the number of the surface to the dividing points on each borehole.During the deciphering process,the sinking and confirmation of the bedding surface can be controlled easily by decipherers.The interaction between the human and computers makes it easy to bring expertise into the deciphering process.The deciphering software developed with the method supplies an intuitionistic interactive tool in the three-dimensional scene,which helps decipherers to carry out deciphering quickly and accurately.Successful application to real borehole deciphering has demonstrated its ability to solve complicated problems in engineering practice.
