Well-logging Rretreatment Based-on Agent

By right of well-logging graph, this thesis mainly researched digitalization tracing and correcting technology . The study can realize well-loggin digitizing store and Intranet data-manipulation based on Agent technology. One data operation user interface was then set up to realize data distributed management of well-logging data.LAG was used to compress well-logging data, which has the merits of relatively high compressed efficiency, quite simple algorithm and the extremely succinct code. The curve-segment can further compress the process of data disposal and solve the problems of the crossing lines and adhesive points at the time of tracing. According to the characteristics of the log-well graph, the correcting arithmetic based on coordinate gridding was proposed, which rectified perfectly the distortion of curve graph. The curve information database was then set up and online manipulation was realized by the assist of Agent technology.This thesis includes five chapters. The first chapter firstly introduced the current situations and necessary reasons of this study. The second one mainly presented the algorithm of curve tracing, described in detail the realiaztion of the LAG data structure and curve-segment ,and then the select of this segment during curve tracing. The third chapter was about curve correction. Possible errors encountered during curve tracing were classified, which was followed by the corresponding correcting algorithms. According to the characters of well-logging , the coordinate gridding correcting method was provided. Chapter four handles for data manipulation based on Agent data, which described the realization of online data manipulation of well-logging by the resort of Agent technology. The last one includes system realization and work summary. The basic constitutes of the whole system were published in this chapter. Summary of the study work followed by future study object were the end of this thesis.
